Brief in counters: by David Coster

2022-04-15

David Coster, Director of Advanced Stone & Masonry Supplies, which sells Stain Proof and Tenax products, talks to Sam Hotten of Stone Sense, the business he started last year in Oldbury, West Midlands.

David: Congratulations on starting your own business last year. Tell us about it.

Sam: With my experience in the market for the past 15 years I thought it was probably about time that, rather than working for other people, I should set up my own business, looking at getting into the retail side to be more customer focussed, working with kitchen retailers... and online, which has become quite popular as a result of Covid.

We’re looking to focus on the Midlands, where I have worked for a long time, although online you have to think nationally, and if a particular project came up that was interesting, we would look at that. We will see where the enquiries come from and where we can find our niche.

David: Do you prefer quartz, ceramic (sintered / porcelain) or natural stone?

Sam: There’s three answers to that. Easiest is doing shed loads of white quartz. It’s all going to be the same so you can produce it quickly and make most money out of it. That’s what I would do if I was the only fabricator in the UK. But it’s also the most competitive, so from a Stone Sense perspective we’re aiming to focus on ceramic, porcelain and sintered stone. I think it offers a lot of opportunity as a new material in the market because many fabricators who are used to quartz say it’s not their preference.

I think a lot of fabricators out there would say if they’re going to work porcelain their preference would be to establish a separate factory, which would be the factory we have opened because we wanted to process porcelain. I think it’s going to form a large part of the market.

On the other hand, if you ask me what I’m going to have in my kitchen at home I’m probably going to say natural stone – quartzite or marble, something like that, which is coming back because you can’t recreate the beauty of it perfectly artificially. Having been in the industry for 15 years you just love the natural element of the product.

Do you take work straight off the machines or hand finish?

I’ll try to do as much as we can on the machines because you have that level of consistency, as long as you have the operators who understand what you can and can’t do – and that changes with the material because you can’t fabricate everything in the same way. We have a five axes waterjet so we can cut any material. But a key investment was the edge polisher. It’s not our most expensive machine but it is important to the business because it reduces the number of people you need for hand finishing.

Health & safety is an issue, so cutting down on employees makes sense.

Machines don’t have as many sick days and holidays. You don’t get the problem of something like Covid with machines. I suppose the thing I have learnt is to put the maximum effort into things you can control, and you can control machines. But don’t get me wrong, my company is built on having a team mentality.

You started your business during the pandemic and with Brexit still being completed. Did they change your plans?

The market got bigger! Everyone is busy. I have worked in the industry quite a long time and in that time technology has changed a lot. We can’t have price increases because we all do the same job and sell the same products. Prices have come down and you have to use the technology available to compete. But your product is not now seen as unaffordable by as many people and the market is bigger as a result, because people want a surface that lasts longer and looks better aesthetically. The benefit of a growing market is that if you have 1% of it, that 1% is getting bigger.

In one of the businesses I was with previously I sat down with an investment fund and they asked me about the size of the market we were in. I quoted stone sales, but they said surely everyone has a kitchen and every kitchen has a worktop. They said: ‘That’s your market, is it not?’

Do you have any more investments planned?

We have made a large investment in machines. From day one we wanted to be on a level with top end fabricators and you can’t be that without top end machines. We have set the business up to be sure we are not having to make any more investments immediately.

Climate change is a big issue. Do you have plans for Net Zero in 2050?

We don’t have a formal plan. Our suppliers are market leaders and they do have plans in place. One problem with this industry is that everything goes in the skip. At home we are very careful about separating out waste for recycling.

Are you finding it hard to recruit skilled people?

Templating and fitting. There’s an issue: kitchen companies want you to employ the fitters you use, and over time we plan to have our own fitters. One of the things we intend to do with our first fitting team is have them also working in the factory, so they make it and fit it. They need to understand the project.

The kitchen showroom is right in saying they know if I employ the fitters they will do a better job than if I sub-contract the work. But the problem we have as fabricators is that the best fitters are self-employed because they used to be employed, until they realised they could earn more on their own. There isn’t that level of expertise available because the market has got so much bigger.

We say fitting should not require a lot of expertise if the templating is carried out properly. To me, templating is so important its untrue. We outsource templaters and give them a tick sheet. You have to cover every item because the templates are going on to the machines. They have to be right. They use Prodim or laser digital templaters, whichever is right for the job. If the templating is accurate and the machining is accurate the job of the installers should be straight forward. Are we short of expertise? We need people who can follow a process. Is that what’s missing?

Have you invested a lot in computer programs for the office?

I use Moraware, which is fairly standard for fabricators. It’s crucial in terms of production, stock system, scheduling system. We put a lot of time into setting up the systems so we were ready to go.

How do you see the market developing?

It’s more competitive, but it’s got bigger, so there’s more opportunity.

You need more investment to get started these days but it’s got easier because you’re just buying machines. You can replace 20 years of skill and knowledge with a machine. When I first came into this industry the big thing was that we had a CNC router – and we would tell everyone we had one. Now everyone has a CNC and everyone needs work to put on the machines. I need my factory to be busy as well and we’re trying to think of where the areas are that we can make more money by being more proactive.

We’re trying to specialise in porcelain and sintered stone and are talking to other fabricators to see if we can be their supply-only company for porcelain worktops, charging them a price that gives them a margin.

Quartzite is also just as much of a pain to fabricate and I could do that as well. In fact, plenty of those who have only been in the industry for five years or so have probably never even worked granite. All they know is quartz. They think granite is stupidly heavy. You say: yes, that’s what we used to use. People will pick it up by the cut-out!

If the niche for us becomes sintered and natural stone, great. I don’t have 10 people in the office quoting to pick up the volume work, so I have to look for niches, and providing something special for the kitchen market that customers are prepared to pay for.

TOOLS: Sweat those assets

2022-04-14

The competences needed in the stone industry are becoming as much about computer and IT skills as they are about traditional trade skills. Improving productivity is not exactly a new idea, but tools are now available to make it easier to achieve – and those tools are digital.

There are new tools making their way into the workshops of the stone industry. They are certainly not the traditional tools of the trade, but companies are rapidly discovering their benefits.

Reducing down-time, improving machine wear and taking the guesswork out of colour-matching are three ways fabricators are investing in technology to get more out of their existing resources.

That was the message members of the Worktop Fabricators Federation (WFF) took from a demonstration day on 8 March organised by WFF sponsors LPE Group, which supplies the stone industry with machinery, tools and equipment, and hosted by manufacturer Zoller at its premises in Derbyshire. LPE sells the Smile tool pre-setters Zoller makes.

WFF at Zoller

Zoller Sales Manager Andy Dyche demonstrating the Zoller Smile to members of the WFF.

Zoller demonstrated its Smile Compact and Pilot machines for measuring and pre-setting CNC tools – both in theory and in warts-and-all practice, thanks to some real-life cutting and polishing tool heads brought in by the attendees from WFF members Natural Stone Surfaces.

The aim of the machines was explained by Zoller sales manager Andy Dyche. He said checking tools are within acceptable gauge and adjusting CNCs to allow for observable differential wear on each tool in a set is bound to result in longer machine and tool life, not so much requirement for cautious ‘touching-on’, and repeatable operations.

The Zoller Smile’s high-level accuracy and repeatability is due to its CNC spindle and auto-focus. It is easy to operate for the professional presetting and measuring of cutting tools, and thanks to its robust construction performs comfortably on the shop-floor.

Zoller Smile

The Zoller Smile tool pre-setter.

The Smile’s variable control unit, ergonomic, single-handed operating handle and freely accessible tool clamp make working more comfortable. Tool readings are transmitted directly to machines seamlessly. 

“The difficulty is that unless you are measuring in the first place, it’s hard to attribute costs, parts or downtime just to tool-setting,” said Andy. “Most foremen and machine operators can’t do that with certainty. But they do understand the costs of re-work. And they certainly understand that if we can prevent one spindle-collision the machine will have paid for itself.”

Zoller reckons busy worktop fabricators who incorporate regular tool-measuring into their tool-room rou-tines should expect to be able to recover the £12,000+ cost of a machine within 12 months.

Also on display – and backed with a similar pay-back claim in terms of reduced re-work and better use of off-cuts – was LPE’s X-Rite portable spectrophotometer.

James Weston and Director Dave Roy from Natural Stone Surfaces, also based in Derbyshire, spoke about the benefits of their X-Rite spectrophotometer during the Stone Digital online conference in February (click here for a report from Stone Digital).

James said then: “This colour checking technology is now digitally advancing the matching of materials during selection and manufacturing.”

Previously, deciding whether the colour of different batches of material matched was often a question of who was looking and under what lighting conditions. It frequently involved some level of discussion and sometimes disagreement.

The X-Rite hand-held spectrophotometer had done away with any debate, and acceptable levels of variation between batches was now determined in advance and ascertained instantly. It had reduced waste by allowing more offcuts to prove acceptable for subsequent jobs and avoided any awkwardness on-site when fitting worktops that clearly do not match.

Some of Natural Stone Surfaces’ suppliers have even started using spectrophotometers to check slabs from different batches to make sure they are colour-matched before delivering them, which has reduced the amount of handling at the Natural Stone Surfaces factory and contributed to the company’s ‘lean systems’ manufacturing.

James Weston was also at the WFF Zoller event, this time with his colleague Chris Hill,  and they again shared their experiences of how this device has taken the guesswork out of materials-matching at the company. He said it is particularly useful on white and marble-effect quartz.

He said the improvements brought about by the spectrophotometers the company uses meant “they paid for themselves within six months by taking the guesswork – and the heavy lifting – out of selecting material to complete jobs”.

LPE is offering WFF members exclusive price deals on Zoller and X-rite machines, providing another reason to join the organisation, if you have not already done so. For information about the WFF contact General Secretary Chris Pateman at administrator@worktopfabricators.org. 

Another new piece of technology that should be available by the end of May or early June is a machine to measure, in real time, levels of respirable crystalline silica (RCS) dust in the atmosphere. It is being introduced by Stone Industry Group (SiG).

Trolex for measuring levels of RCS

The Trolex Air XS for measuring levels of respirable crystalline silica in the air.

The device is called Trolex Air XS, and is said to be more than twice as accurate as the X-Ray diffraction units currently used to measure RCS levels, as well as giving instant readings, which you don’t get with X-Ray diffraction.

The unit was introduced to members of the Worktop Fabricators Federation (WFF) at their meeting at machinery company Intermac’s premises in Northamptonshire last year, when volunteers were recruited to carry out field trials. The development of the unit by British company Trolex is now almost complete. It will be sold to the stone industry by SiG in the UK and also in America and Europe.

It was introduced to the Americans at StonExpo/Marmomac in February, part of the International Surfaces Event in Las Vegas. And it won the ‘Best of Technology 2022’ award at the exhibition.

Among those manning the exhibition stand in Las Vegas was Ash Butler, who has now joined SiG and will be selling the Trolex Air XS in the UK.

SiG wins Best in Show Award at Surfaces in America

SiG Director Simon Bradbury (second left), SiG Inc President Jerry Van Der Bass and Ash Butler (right), who has recently joined SiG and will be selling the Trolex Air XS in the UK, receiving the ‘Best of Technology Award’ at the International Surfaces Event in Las Vegas in February. Ash said the Air XS received the award because the judges could see where the industry is going in terms of the need for proactive dust monitoring. He says the UK is only a few years behind the US.

In the USA the permitted workplace exposure level to RCS is half the current level in the UK, although the All-Party Parliamentary Group for Respiratory Health (APPG) said in its 2020 report, Silica – the next asbestos? that the UK level should be reduced to the American level, although the Group is currently reviewing its recommendations in the report.

In the British sandstone industry the risks of breathing RCS are taken seriously and people are routinely protected by substantial PPE, including positive pressure helmets – and SiG says it is also introducing a positive pressure helmet to its range.

SiG Director Simon Bradbury discovered the positive pressure helmet he is introducing during Covid. It was developed during the coronavirus pandemic to protect key workers from the Covid-19 virus. It is effective but lightweight for comfortable use over sustained periods.

At worktop fabricators in the UK, protection often involves a mask over the mouth and nose that might or might not fit properly and be worn regularly by the operator.

Even when worked wet, RCS will float in air-born water droplets that can be inhaled. Health & Safety Executive (HSE) tests have shown air-born levels of RCS can exceed legal exposure limits outside as well as inside CNC machine enclosures. Using angle grinders/polishers, wet as well as dry, also produces RCS levels in the air well above legal limits.

“In the USA fabricators are putting warning stickers on slabs saying there’s an inherent risk of silicosis from handling and cutting this material,” says SiG Director Simon Bradbury. In the UK the HSE is getting ever more vigilant about dust in general and RCS in particular because silicosis is second only to asbestos as the cause of lung disease in construction.

The Trolex Air XS is mobile, so can be used to test the RCS levels in different areas of a factory. It has a price tag of just under £10,000, but Ash Butler says if companies look on it as an investment to protect their employees, and themselves from injury claims, it does not seem too high a price to pay.

Flexijet and Optimo from Stonegate

Stonegate continues to innovate with the Flexijet digital templater and Optimo tool set-up service.

Optimo from Stonegate

From Stonegate there is Optimo, a service for measuring CNC profiling tools using the Zares II 3D optical measuring device created by MainAxis. Combined with the expertise of Stonegate’s CNC Technicians, Stonegate says this creates the ultimate system of tool setting.

OPTIMO

Developed over three years using Stonegate’s experience and relationships with both CNC manufacturers and customers, as well as the hands-on experience of its technical team, Optimo is a service that has proven to significantly improve productivity.

With technology used by opticians, Optimo measures CNC profiling tools to five micron accuracy (0.005mm) through a full 360º.

The benefits of this level of accuracy include:

  • Reduced set up time – it takes approximately 15 minutes instead of a laborious four hours.
  • Human error is almost eliminated. The operator copies measurements supplied by Stonegate into the CNC operating system. This also reduces the number of tools accidentally damaged during set up.
  • Increased tool speed by a stated 30%, although in practice Stonegate has found many businesses do even better than that.
  • Longer tool life. The tooling only works as hard as it needs to and it’s right first time.
  • A final polish straight off the CNC with no need for hand finishing.

Stonegate now also offers Optimo Rental for practically plug and play tooling set-up. There’s a one-off standard charge for up to 10 linear metres with a charge per metre thereafter. Customers can have the edge profiling of their choice at a set rate, with all tools supplied in a handy travel case, ensuring they are in pristine condition when they arrive.

Carl Hazell, Director at Stonegate Tooling, says: “Feedback so far on the Optimo service as a whole has been extremely positive, with customers saving hundreds of pounds in set-up time.” He says initial trials on the Optimo rental service have also proved popular.

Flexijet from Stonegate

Flexijet templating from Stonegate.

FLEXIJET

Stonegate has become the accredited UK distributor for Flexijet, for easy and precise measurement of countertops and other surfaces.

Here’s what Flexijet offers:

  • Instant auto-levelling. Flexijet has an internal tilt sensor, so setup is quick.
  • Integrated shock sensor. If the device is knocked, a warning appears on the touch display and in the software.
  • Error elimination. Measure complex angles and shapes with no possibility of wrong or forgotten dimensions.
  • Remote control for complete flexibility.
  • Built-in camera for site photos and a voice recorder.
  • Full 3D image of the template you are creating.

Since becoming the accredited UK distributor of Flexijet, Stonegate says feedback has been exceptional, due to the accuracy and ease of use of the equipment.

Stonegate also offers a wider service of analysis and reporting on both Flexijet and Optimo.

A Qualified Workforce: by Mark Priestman

2022-04-14

Mark Priestman is a Director of a training consultancy whose mantra is: Qualify the Workforce! Here he offers some guidance on NVQs and CSCS cards.

Qualifying a workforce is accomplished through a range of methods:

  • Training programmes
  • Apprenticeships
  • Mentoring
  • Access to gaining experience
  • Qualifications
  • Continuous professional development (CPD).

Many in the workforce are skilled but don’t have a certificate to authenticate their skills. Without a qualification they can’t get a CSCS skilled worker card and it can be harder to get employment.

I’ve spoken at length previously about apprenticeships and specialist applied skills programmes, but thought I should now address the needs of experienced workers who are as yet uncertificated, perhaps because they never got around to it, or because CSCS cards were not previously required as often as they are now, or because they had a card through grandfather rights that have now been withdrawn.

On-site assessment, otherwise know as OSAT, is a method of assessing experienced workers for their NVQ.

Most of the learning requirement is stripped away and the person has instead to build a portfolio of evidence of their skills, and submit to a site visit and a recorded professional discussion.

What occupational areas are available as NVQs? Well, I can tell you those my own business offers.

For managers, there are Level 6 NVQ diplomas in:

  • Site Management – Building & Civil Engineer
  • Site Management – Conservation
  • Contracts Manager

For supervisory occupations, Level 3 NVQ diplomas in:

  • Occupational Work Supervision
  • Contracting Operations
  • For advanced craftsmen and women, Level 3 NVQ diplomas in:
  • Banker Mason

For heritage skilled workers, Level 3 NVQ diplomas in:

  • Heritage Skills Façade Preservation
  • Heritage Skills Mason

For natural stone and façade preservation operatives, Level 2 NVQ certificates/diplomas in:

  • Façade Cleaner
  • Façade Restorer
  • Façade Cleaner & Restorer
  • Stonemason Banker
  • Stonemason Cladder
  • Stonemason Cutter
  • Stonemason External Fixer
  • Stonemason Internal Fixer
  • Modular Pavement Installer

So, what is involved for the learner and their employer in being on an OSAT NVQ programme?

Generally speaking, assessment is less scary in practice than it is when contemplating it.

Additionally, fees for assessment have generally not risen in recent years to assist with the economy, Covid, Brexit and now the fall out from the war between Russia and Ukraine.

To keep assessment fees down, providers like ourselves are doing more on Zoom and via the telephone, and leaving site visits for the essential observation element of assessment. Additionally, learners (or their employers) are encouraged to upload evidence digitally to shared folders, further streamlining the assessment process.

A candidate will be asked to collect video and photo evidence of their activity at work and provide work diaries and copies of any certificates already achieved related to the NVQ occupation.

Following a desk assessment of all this evidence the assessor will contact the learner and arrange to observe them at work and carry out a recorded discussion.

Once the assessor is satisfied the learner has met the national occupational standards for the NVQ, they will submit a claim, which will result in internal and external quality assurance of the portfolio evidence and the assessor’s claim.

Where successful (and so far all our claims have been) an NVQ certificate is issued by the awarding body and sent to the learner.

On the basis of this NVQ certificate, the individual can apply for the appropriate CSCS card after successfully completing the relevant CSCS touchscreen test. While the card needs renewing every five years, which means another touch-screen test, the NVQ is a qualification that lasts a lifetime.

If you can’t find the right construction NVQ for you, get in touch with me on the phone number or email above and I will be happy to help.

Company fined after wall collapse leads to child’s toe being amputated

2022-04-12

Gurmit Properties Ltd has been fined £22,500 and ordered to pay £11,998.80 costs for safety breaches after a substantial part of a wall at a construction site in West Yorkshire collapsed, injuring a child and leading to the amputation of her toe.

The company appeared before Leeds Magistrates’ Court on 12 April. The court heard that Gurmit Properties Ltd (GPL) was the owner of the site in Barnsley Road, South Elmsall when the wall collapsed.

The company had previously received a large delivery of aggregate, which was deposited on land next to the construction site. Officials from the local council attended the site and ordered the material to be removed. GPL brought the materials on to its site, storing it behind the wall that collapsed.

On 7 February 2018 an eight-year old child and her mother were walking along Harrow Street, adjacent to GPL’s construction site, when the wall collapsed. The child was hit by debris and sustained injuries that included crush injuries to her foot that resulted in the amputation of her big toe on that foot.

An investigation by the Health & Safety Executive (HSE) found that GPL had not assessed the structural integrity of the wall to ensure it was safe to be used as either a secure boundary for the site or as a retaining wall for storing materials. When the materials were stored against the wall it failed, leading to the collapse and the injuries to the child.

GPL were a client and a contractor within the meaning of the Construction (Design & Management) Regulations 2015, and failed in their duty to ensure that the wall was either safe for use as a secure site boundary or as a retaining wall for storing materials.

Gurmit Properties Ltd, based in Albion Street, Castleford, West Yorkshire, pleaded guilty to breaching Section 3 (1) of the Health & Safety at Work etc Act 1974.

After the hearing, HSE inspector Chris Tilley commented: “The company should have appointed a competent person to carry out an assessment of the wall at the start of the project to establish whether it was safe to use as a boundary wall, and then carried out a similar assessment when the wall was used as a retaining wall for storing materials.

“This incident could have been avoided by simply carrying out correct control measures and adopting safe working practices.

“Companies should be aware that HSE will not hesitate to take appropriate enforcement action against those that fall below the required standards.”

HiMacs in Paradise

2022-04-11

The bar pictured above is at the Paradise Now restaurant / bar / bistro / club in the MedienHafen district of Düsseldorf, Germany. The bar is made from solid surfaces from HiMacs.

Paradise Now is owned by restaurateur Walid El Sheikh. The 1,000m2 interiors of the new venue were the work of Moritz von Schrötter and Charles Bals from design agency Parasol Island.

High ceilings, bright colours and carefully positioned lighting create a relaxed ambiance, the prevailing whites of the base startled by splashes of colour, with organic shapes, wicker furniture and plants completing a tropical interior.

The feature you can’t miss is the 16m-long bar with its spectacular custom-made counter.

HiMac Arctic White was used for the work surface at the back of the counter, while Ispani from the LX Hausys Marmo collection, with its randomly veined look of marble and also from HiMacs, was used for the countertop, front and sides.

LX Hausys is the new name given to LG Hausys, the maker of HiMacs, last year following the sale of the company to the Korean LX Group.

When the bar is lit up, the marbling of the solid surface material shines through even more. Wall panels in backlit HiMacs, with insets at different depths, cover 10m of the wall behind the bar, visually striking but also practical as shelves for glasses and bar utensils.

The fabricator Karl Heller GmbH from Düsseldorf was responsible for the customisation of the spectacular counter.

Walid El Sheikh first came across HiMacs solid surfaces in a hotel bathroom. He says he was “immediately taken by the unique look and feel of the solid surface material”, so wanted it in his new venue. And it is ideal for this high-traffic use because HiMacs is durable, stain-resistant and easy to clean.

Heatpumps: The sustainable alternative to gas

2022-04-11

The government has set a target of at least 600,000 heat pump installations a year by 2028. Heat pumps work best with underfloor heating and underfloor heating works best in association with the thermal mass of natural stone tiles. Could this be the start of a new stone sector specialisation?

It is vital that the Government should meet its target to deliver a minimum of 600,000 heat pumps a year by 2028 or there will be a great risk it will fall off course in delivering Net Zero by 2050.

So said the Business, Energy & Industrial Strategy (BEIS) Select Committee of MPs in its seventh report on decarbonising homes, published in January this year.

It complained that the Government has not outlined in its delayed Heat & Buildings Strategy its plans for how it will meet its heat pump target or what contingencies are in place if the target is missed.

In the Heat & Buildings Strategy the government has introduced a grant of £5,000 for householders and landlords towards the cost of installing air source heat pumps (£6,000 for ground source heat pumps) to replace gas boilers in existing properties in England and Wales starting from April.

The grant is not available for new builds, but gas boilers are banned in new builds from 2025 (which the BEIS Select Committee wants brought forward to next year) and builders will have to include heat pumps, or some other low carbon alternative to gas boilers, in new properties in order to make them carbon neutral ready. Many are already including heat pumps in order to make properties easier to sell.

It might not be pretty but it could help save the planet.

Boosting demand

The grants to help with retro-fitting heat pumps in existing properties come with a budget of £450million over three years. So that’s a maximum of 90,000 properties that can benefit, while the Office for National Statistics says there are 27.8million households in the UK, 85% of which use gas boilers for heating and hot water.

The grants will be distributed to the  companies that install heat pumps. They will apply for the grant on behalf of their customer and the grant will be discounted from the total price the homeowner pays.

If you can see a potential problem with that you are not alone. Government subsidies often simply increase the price of the goods being subsidised, even if for no other reason than demand increases. And the government does intend the grants for heat pumps should boost demand for them.

However, with air-source heat pumps (which are the cheapest kind available and what the vast majority of people choose) typically costing £10,000 to £20,000 for most homes, and ground source heat pump installations at between £13,000 and £35,000, critics say the grants will be an inadequate incentive for most people.

The result will be that the money will go only to those who could have afforded them without the incentive, perhaps particularly private landlords (the grants are not available for social housing).

Some argue that more efficient, larger scale underground heatpump systems covering all the houses in a development, for example, should be the longer term aim.

They would have to be maintained by an energy supplier who would charge the householders a fee, in the same way as gas suppliers do now, which creates a market solution and spreads the cost of energy supply over an individual householder’s lifetime in a familiar fashion.

The government has stressed that households will not be forced to remove existing gas heating systems, although they will be unable to replace them with the same systems when the sale of gas boilers is banned all together –whenever that might be.

No more boilers?

The independent Climate Change Committee (CCC), a statutory body established under the Climate Change Act 2008 to advise the government, says it should be no later than 2033. The government has said it will introduce a ban in 2035, but there has been a lot of opposition to that and it looks as if the date might be put back to 2040.

Such vacillation does nothing to encourage householders to get on and make the change. Some even express doubts that a change will ever be necessary as hydrogen could be used to burn in boilers, at first as a mix with natural gas to reduce CO2 emissions and eventually just pure hydrogen.

If hydrogen could be economically split from water, burning it in a boiler would simply turn it back into water. The technology already exists, although a step change in hydrogen production would be required to make it viable to supply through the mains. Nevertheless, some think it makes installing a heat pump look like a white elephant – although rapidly rising gas prices might prove to be an incentive to install heat pumps for those who can afford them.

Many in the construction industry say a concise roadmap to phase out the sale of gas boilers by 2035 would have been much more effective than a limited number of £5,000 (or £6,000) grants, especially if such a roadmap was accompanied by significant funding, such as the £2billion allocated to the failed Green Homes Grant before it was withdrawn with 95% of it unclaimed.

The BEIS Select Committee seems to agree. In its seventh report it opined: “The Government should work with industry, consumers, and affected workers to produce an effective road map detailing how the transition to low carbon heating will take place, and to include what this will mean for different households in different parts of the country and for workers whose jobs might be affected in existing carbon intensive parts of the heating sector. We recommend this is done at local level in partnership with local government. The long overdue Heat & Buildings Strategy published in October 2021 failed to provide sufficient policy detail or clarity on delivery.”

So far, the installation of heat pumps, nearly all of them air source versions, has been limited. In 2019, 34,896 hydronic heat pumps (which transfer heat using circulating water in the same way as a gas boiler heats water circulating in radiators) were sold in the UK. That number includes hybrids, which include an alternative heating source such as a gas boiler, because heat pumps are not usually capable of providing both heat and hot water at the same time, so an alternative system is used to provide hot water from the taps.

There are £6,000 grants available to help pay for the installation of ground source heat pumps, which typically cost between £13,000 and £35,000.

Not enough installations

In its 2021 Progress Report to Parliament, the CCC stated that “despite a small improvement in the rates of heat pump installation, these remain far below the levels that are necessary”.

It noted that annual heat pump installations in homes had risen marginally to 36,000 in 2020, driven mainly by an increase in retrofit installations of just under 23,000.

It is also starting to become clear that retrofitted heat pumps are not living up to householders’ expectations of their heating, and some of those who have had heat pumps installed, who tend to be at the wealthier end of income brackets, are also subsequently having new gas boilers installed to keep their homes cosy.

One of the problems is that heat pumps are being installed to work with existing central heating systems that have wall-mounted radiators. A gas boiler would be expected to heat those radiators to 70-80ºC in order to keep a room at a comfortable 21ºC. Heat pumps deliver water to the radiators normally at no more than 40-50ºC. That’s the sort of water temperature range most people would shower in.

To produce water temperatures of 50°C, the Coefficient of Performance (COP) of a heat pump is approximately three (so for every one unit of electricity used to power the heat pump, it produces three units of heat). As radiators are typically sized for a flow temperature of 71–82ºC, those in most houses would be undersized for use with heatpumps.

To achieve the same level of heating as a gas boiler achieves in existing properties will normally mean improving insulation and increasing the size of radiators or replacing the radiators with underfloor heating or, in smaller properties, air-to-air blowers.

Most people installing heat pumps do not make sufficient provision for increasing insulation and do not replace the radiators. They would not, in many cases, want to increase the wall area taken up by the radiators or the thickness of them in order to achieve the levels of heating they enjoyed with a gas boiler.

Consequently, they find the heating inadequate, leading to the subsequent installation of another source of heating, usually a gas boiler. Not ideal when the aim is to reduce CO2 missions.

Householders who have had heat pumps installed and found them inadequate also tend to talk about it. Word quickly spreads, which is not good news for the government’s 600,000 unit-a-year target for 2028.

The issues of insulation, radiator size, and alternatives such as underfloor heating are not often subjects raised by companies installing heat pumps. They tend to want to install the unit as quickly as possible and get on to the next job. Some even disingenuously advise against having underfloor heating for no other reason than they don’t want to get involved with installing it, they don’t know how to do it, and/or they don’t want to frighten the customer with the extra cost involved.

Ireland commits €8billion

In Ireland, the government announced in February its plans to provide funding of €8billion that is intended to pay for energy upgrades to 500,000 homes by 2030. Heat pumps will play their part.

The commitment is spread over eight years in order to give companies involved in the sector the confidence to invest, expand and create more high quality jobs without fearing that the bottom will suddenly fall out of the energy upgrade market.

Speaking at the launch of what is called the National Home Energy Upgrade Scheme, Taoiseach Micheál Martin said: “Today, the government is committing to support people in making their homes warmer and less expensive to heat, while also tackling our climate change crisis.

“The Irish people responded collectively, and with a sense of purpose, to the pandemic by helping protect the most vulnerable in our society. The climate crisis is just as critical for our children and future generations, as well as people at risk of fuel poverty now.

“This government’s commitment to reaching our climate ambitions is clear, and today is another step along that journey.”

Ireland has already seen the benefits of the multiplier effect of injections of investment in infrastructure from its membership of the European Union and it believes €8billion now will achieve a similar significant multiplier effect, supporting the development of associated supply chains and a transition to a carbon neutral society without anybody being left out in the cold.

Key measures in the Home Energy Upgrade Scheme include grants of up to 50% of the cost of a typical ‘deep retrofit’ for most people, but also free upgrades for those at risk of energy poverty.

There are grants of 80% of the cost of attic and cavity wall insulation to reduce, as a matter of urgency, the country’s energy use –  part of the government’s response to the latest shock of rising energy prices.

The Home Energy Upgrade Scheme is also offering a start-to-finish project management service, including access to financing.

Carbon tax funding

The schemes is being administered by the Sustainable Energy Authority of Ireland (SEAI). The increased grant supports and the significant ramping up of free energy upgrades for those at risk of energy poverty is supported by ring-fenced funding from the carbon tax.

This year, €267million has been allocated for SEAI residential and community schemes. This will support about 27,000 home energy upgrades, taking some 8,600 homes (twice as many as last year) up to a Building Energy Rating of B2 (which can involve photovoltaic [solar] panels and heat pumps). B2 is generally considered the benchmark for an excellent performance in a home built before 2006. The budget will also facilitate 4,800 free energy upgrades for those at risk of energy poverty.

Polycor continues expansion by adding another Indiana limestone company

2022-04-10

Polycor Inc in Canada, which merged with Indiana Limestone (ILCO) in 2018 and took over another American Indiana limestone company, Elliott Stone Company Inc, based in Bedford, Indiana, in 2019, has now reached an agreement to acquire Evans Limestone in Indiana.

Patrick Perus, CEO of Polycor Inc, says: “The acquisition of Evans Limestone continues our history of strategic growth. This acquisition expands Polycor’s access to the highest quality natural stone products while also expanding our geographic footprint.

“This is truly another exciting time for us as we continue our commitments to providing leadership in the industry and to providing premier products to our customers. We are very excited to welcome the Evans Limestone products and stone experts into the Polycor family.”

Evans Limestone’s roots date back three generations and over the years it has built a reputation for expertise in producing high quality products for smaller, high profile architectural applications that include the Tuscaloosa Federal Building and Courthouse, the Pennsylvania Judicial Center, and the United States Holocaust Memorial.

Stephen Evans, the President of Evans Limestone, says: “Across generations of time in this industry we have developed a reputation for hard work and exceptional products. We are very pleased to be joining the Polycor family.

“Polycor’s vision and values are directly in line with Evans Limestone’s, and we look forward to bringing our history and expertise to the world’s leading natural stone quarrier. Together, we will continue to do great things for our customers and for our employees.”

Polycor’s quarries include four in Burgundy, France, previously operated by Rocamat that it bought in 2018. The stone from them includes the celebrated Massangis stone, as well as Rocherons, Charmot, Comblanchien, Lens and Valanger. These stones can be seen in France on such famous structures as the Louvre, the Louis Vuitton Foundation and at the base of the Eiffel Tower.

They have also made their way to the UK and the fact that Polycor would like to sell more in the UK is clear from it having joined Stone Federation Great Britain.

Founded in Québec City, Canada, in 1987, Polycor company employs more than 1,300

people and owns more than 50 quarries and 20 manufacturing plants in North America and Europe, laying claim to be the largest dimensional stone company in North America. It has committed to being carbon neutral by the end of 2025.

The acquisition of Evans Limestone, a member of the American Building Stone Institute and the Indiana Limestone Institute, adds another quarry and some 30 employees to Polycor.

Power-up interior walls with TheWall

2022-04-09

Imagine walls with built in powered strips for holding devices such as phone chargers, lighting or even a television screen that can be moved to wherever you want to position them.

That is the brainchild of Johannes Falk and he is looking for worktop fabricators in the UK to supply such systems.

Under the trademark of TheWall, based in Germany, he supplies the patented, ready to go ‘plug and play’ frame and all the accessories that can fit into it. The fabricator adds the decorative surface and fits it.

Johannes believes it is a way of adding value to splashbacks and wall linings in kitchens, bathrooms, offices, bedrooms and living areas. It has already caught the imagination of kitchen companies including the new owners of Lechner in Germany and Dekker in The Netherlands.

Now TheWall is coming to the UK, where the company is being represented by Philip Winter, who has previously worked with Italian Luxury Surfaces / Stone Italiana and before that was the UK MD of a German kitchen company.

In the UK, the worktop market is more fragmented than in some mainland European countries and Johannes hopes to work with a number of first rate regional companies being identified by Philip Winter.

Johannes wants to limit the number of fabricators involved because he wants to be sure of the quality of the work, as TheWall products are up-market and poor workmanship would compromise that position.

Johannes says the idea for TheWall came to him from Vitra rail lighting used by shops. They lack the aesthetics to be used in kitchens, bathrooms or living areas, but a trip to a lighting company in Austria resulted in the development of a powered rail with lighting that could be moved to any position on the rail and just clipped in place for up or down lighting.

That was the start of TheWall. Since then Johannes has developed a whole range of quality products, powered and not powered, that just clip into a frame. “We want to bring hundreds of interesting items to TheWall,” says Johannes. The accessories are bought online only from the-wall-shop.com.

Johannes says he once worked for Apple, where he learnt that what people want most are products they can unwrap and use straight away, and that is what TheWall offers.

He says it is totally safe, and even if fingers or anything else are poked into the gap that the accessories fit into it is not possible to get an electric shock.

Philip Winter says: “It's an innovative, flexible rail system that brings functionality to 'inert' splash-backs and wall installations. The finished products are delivered as 'plug and play' ready to install units, including all electrical connections. The precision alu-frame creates a very stable platform for 6mm ceramics.”

He says once the surface has been added to the frame it becomes exceptionally robust.

The frame and electrics do add to the thickness of the installation and 46mm clearance is required.
