Thorn luminaires help revolutionise facilities at a Samuel Ward Academy in Suffolk

,

Working on a brief to deliver a first-class facility for the pupils and teachers, Thorn Lighting has supplied both internal and external illumination for the £10 million education block that has revolutionised facilities at a Samuel Ward Academy in Suffolk. The luminaires were chosen to enhance the overall appearance of the state-of-the-art facility and create flexible and adaptable 21st Century learning environment for pupils, whilst providing a low maintenance, energy efficient solution.

The three-storey building replaced the school’s single-storey blocks A and B, which sat at the front of the building and, in addition to classrooms, the block houses the library, the SEN (special educational needs) resource base, specialist music and art rooms and media suites. Funding for the work came from the Government’s Priority School Build Programme with the building providing high standards in terms of natural daylighting, acoustic performance and the internal environment.

 

Thorn’s Arena LED luminaires illuminate the classrooms throughout the building. Their excellent light quality and sound absorbing features minimise the sound reverberation in the classrooms. Modern concrete walls, hard flooring and large amounts of glass all reflect (rather than absorb) sound. The echo effect created in this way can make it difficult to hear the teacher speak, causing students to raise the noise level even further by chatting amongst themselves. The innovative Arena LED minimises this.

Arena is a direct/indirect luminaire that gives the Academy a modern visual appearance. The fitting is available with a wide range of control options and has been designed for flexibility, offering a choice of infills to adapt the length of the system to match all classroom layouts, Arena is fully compliant with BB93 for optimum classroom performance, utilising high-efficiency LEDs to slash energy consumption.

Thorn’s Piazza robust IP65, wall mounted luminaires have been used for the illumination of the exterior of the building. Piazza has unique photometrics with 3 metre forward light throw and 12 metre spacing that also provides a very low upward light throw with less than 2.5% ULOR. Piazza delivers excellent 116 lm/W efficiency with simple installation.

INSTANT HOT WATER WITH ARISTON’s AURES SLIM MULTI

,

ARISTON’S AURES SLIM MULTI PROVIDES ELECTRIC HOT WATER IN AN INSTANT

The Aures Slim Multi instantaneous electric water heater from Ariston is the ideal alternative to electric storage water heaters, as it requires no time at all to heat up. Water does not need to be stored – instead, it is warmed up immediately when it comes into contact with a powerful heating element as it flows through the unit, resulting in unlimited availability on demand. As a result, the Aures Slim Multi can be installed throughout a home or property close to point of use.

 Capable of producing hot water to serve multiple taps and showers (one outlet at a time – not simultaneously), the Aures Slim Multi is a wall-mounted unit perfectly suited to applications such as kitchens and bathrooms. It also has an ‘A’ class ErP energy rating, making it the most efficient method of providing water at the point of use. There is no energy loss as a result of water being heated instantaneously, while there is no need to maintain a pre-set temperature when not in use. Units are also easy to install and maintain, requiring only a connection to the water supply and a fused spur.

A front facing 4-step dial and LED indication ensures ease of operation, while allowing the power to be set to the desired level for optimal comfort. The LED indicators highlight the selected power level: ‘low’ (4.5kW), ‘medium’ (5kW) or ‘high’ (9.5kW). The Aures Slim Multi is also equipped with a flow sensor system, which initiates instantaneous water heating when an outlet is opened.

 

 

Other advantages include the plentiful, continuous delivery of hot water not being limited by the capacity of a tank, while small dimensions save valuable wall space – as well as eliminate the need for a storage cylinder. This makes the Aures Slim Multi the perfect water heating option for installation in small, narrow spaces, such as under a kitchen sink. As a result, the unit is suitable for applications including utility rooms, garages and conservatories.

Commenting on the instantaneous electric water heater, Victoria Gutierrez, Marketing Manager at Ariston, said: “Our Aures Slim Multi is proving extremely popular in projects where there is no mains gas supply or hot water storage facility present. Their high-quality construction, aesthetic appeal and level of performance, coupled with their space and energy saving credentials, ensure they are a fantastic means of supplying outlets with instant hot water.”

All internal components can be accessed from the front of the unit for easy maintenance, while a double thermal cut-out ensures safety and added peace of mind. Every Aures Slim Multi electric instantaneous water heater is also supplied with a two-year warranty as standard.

Roofspace Solutions’ i-House helps Lovell build better

,

Roofspace Solutions’ innovative off-site manufacturing (OSM) product i-HouseTM – which guarantees a waterproof dwelling in five days – is being implemented in a Lovell Homes site in Norwich. The result is a 35% timesaving compared to traditional building methods.

 Leading partnerships housing expert, Lovell Homes, prides itself on transforming communities across the UK. As part of its commitment to innovative residential construction and regeneration projects, it chose to embrace i-HouseTM OSM technology by Roofspace Solutions during the building of its latest development.

Crown Meadows in Norwich comprises two, three- and four-bedroom homes. Construction began in June 2020 and is planned to complete in two years – or possibly sooner as Roofspace Solutions’ i-House can create a watertight standard house shell in under a week, while combining quality, speed and safety.

In addition to speed, Lovell Homes specified i-House in 15 of the 69 Crown Meadows plots as part of its aim to reduce waste and dust, while also minimising the risk of accidents.

 

 A new way of working

The i-House uses a bigger and lighter variant of the aircrete block, which are lifted by crane and assembled in a similar sequence to a timber frame build. This results in a much faster construction process than a traditional build.

Intended for domestic property construction of up to three storeys, i-House consists of inner leaves of external cavity walls, separating walls, floors, lintels, cavity closures, insulation and roof trusses, with the inclusion of soffit and fascia for the internal skin of the property.

Roofspace Solutions is working alongside supplier H+H to design and produce the large-scale Celcon Elements, which are manufactured from the same material as the aircrete blocks. This gives them the same advantages, such as outstanding thermal performance and reduced heat loss at thermal bridges.

Manufactured with a width of 600mm and a thickness of 100mm, Elements are designed to be craned into place onto a bed of mortar on standard foundations. Blocks are joined using thin-joint mortar with 2mm (3mm) joints, providing an extremely airtight finish.

The fact that the solution is manufactured off-site, and larger elements are constructed prior to being delivered to the site in Norwich, means less waste and dust is created for workers. This results in a safer and cleaner working environment. Furthermore, workers on site are not exposed to chemicals.

Crucially, as the homes are watertight in under a week, it has increased Lovell Homes’ construction programme, allowing internal trades to begin their work sooner than with a traditional build.

With the additional consideration of building during the time of Covid-19, the OSM solutions enhance Lovell Homes’ stringent social distancing protocols. At the Crown Meadows site, approximately four builders will be able to build six houses in four weeks, with i-House increasing the output per person.

The i-House package also includes floor cassettes and JJI-Joists provided by Pasquill, sister company of Roofspace Solutions, due consistency of quality and supply and a nationwide delivery service. A total of 60 cassettes will be provided to the same 15 OSM plots on the Crown Meadows development, with each home’s first floor containing an average of 3-4 cassettes.

The Pasquill cassettes, which are made with chipboard and softwood, are ideal components to work alongside the i-House as they facilitate faster timescales and dramatically speed up the erection process. This increasingly popular method allows the contractors to install the floors in one day with little on-site work required.

The cassettes are also installed with Pasquill’s JJI-Joists, also known as I-beams, to create ‘quiet’ floor solutions and consistent dimensions provide extra stability. They do not need insulation to gain compliance with Building Regulation Part E (sound) when installed at 400mm centres and above. They are lightweight, stable, easy to run services through and cost effective.

 

 

Building better results

Paul Terry, Managing Director of Roofspace Solutions, said: “The construction industry is facing many challenges. The only way we will be able to ‘build back better’ and meet government and industry targets for housebuilding is by working together and embracing new technologies.

“The Crown Meadows development is coming along well, and we’re glad that Lovell Homes is already experiencing the time-saving benefits from i-House and Celcon Elements. We’re enjoying working on this project with a developer who has such high standards and look forward to seeing the site completed.”

Chris Gray, Senior Construction Site Manager at Lovell Homes, said: “I believe Crown Meadows will be a much quicker build, from start to finish. Of course, it’s difficult to compare like-for-like, but recently a plot went from being a concrete pad to us laying the roof tiles within two weeks – everything fits like a Lego set!

“Based on the success so far, it’s now our ambition to bring in the development a few months ahead of schedule. For the construction industry, it’s another tool to help us get the job done well and meet the demand for housing – while reducing waste and accidents on site.

“The fact it allows us to make a property watertight so quickly has immediate benefits, such as completing the show home quicker, allowing us to drum up local homebuyer interest sooner. Overall, I think this is a flexible solution that would have really useful applications during the winter or further north, where it typically rains more.”

Roofspace Solutions has been part of the Saint-Gobain Group since 2018, as part of its Off-Site Solutions division.

Don’t let water be the ‘log jam’ in housing developments

,

Modern Methods of Construction have been highlighted by Robert Jenrick, Secretary of State as the way forward to help resolve the housing crisis and urged Housing Associations and Local Councils to embrace new technology and methods of working.  However, the log jam to completion of new build projects can be connection of the water supply.  Surface mounted meters allowing ‘plug and play’ style installation can be the solution.

The recent change in lifestyle forced upon us by the COVID 19 pandemic has identified the importance of home and local community environment. In the Secretary of State’s speech to the Chartered Institute of Housing, 10th September 2020, Robert Jenrick, highlighted the impact the period of lockdown had on those with poor housing and the homeless.
The slow-down in new home build that resulted from the COVID 19 restrictions needs to be reversed and Jenrick has made MMC ‘central to the delivery of the new Affordable Homes Programme’ and set a minimum target for the use of MMC1.  His aim is for ‘…the UK to be a leader in MMC, driving new jobs, better skills, as well as faster delivery of homes, and those homes, in turn, being better quality and more energy efficient, with all of the benefits of society and social justice that comes with that.’1
Jenrick urged rapid progress on Social and Affordable Housing.  However, utility connections can often be the weakest link in the improved efficiency the MMC provides.
Water supply is perhaps the most important item within the critical path of construction and is probably the most difficult to achieve. Imagine a situation where your services can be fully installed prior to moving on site, with surface mounted meters allowing ‘plug and play’ style installation.

With Groundbreaker water management system, you have exactly that ‘plug and play’ option – no need to imagine.
The only system of its type, it is designed to be installed at any time during the construction period.  Fully compliant with Water Regulations, it provides an accessible, safe and secure location for the water meter and controls to a specific property.
The concept is simple.  Water services are connected to an externally mounted, pre-installed water service control.  The pre-installation and certification of plumbing can facilitate early approval of water services to a plot.  This allows flexibility in the management and scheduling of a connection to the water mains supply.
There is no need for boundary boxes or meter housings in the footpath, and this simplification of the connection allows for improved efficiency and reduces the time required for highway closures.  An added benefit of removing meter housing from the footpath is that there is no disruption to the footpath, so no reinstatement costs.
Using Technology to Future Proof Housing stock
It is good to see that Jenrick has recognised the need to embrace new technology, to future proof housing stock. Utility companies have not been slow in recognising the benefits of a ‘Smart Home’.  The ability to interrogate and manage energy usage at any given time of day or night has been recognised as an effective way for householders to reduce usage and manage costs
Gas and electricity meters located on external building walls have enabled easy upgrades and introduction of countrywide ‘Smart Meter’ programmes.  However, the traditional location of a water meter in a metal-covered hole in the public highway is not conducive to this new way of thinking. A ‘Smart Water Meter’ located in such a situation is exceedingly poor in transmitting a signal even to a local pick up. With Groundbreaker water management system, ‘Smart Water Meter’ technology can be easily installed, as it is introduced across the UK.  Recent field trials of Groundbreaker have proven that the range of such meters can be over 3Km (2 miles) allowing for remote access and the ability to mange the carbon footprint.

Modular construction is the future – but is it missing something?

,

Nick Gander, founder of Energy Carbon, explains why low-carbon far-infrared heating perfectly complements sustainable modular construction.

When it comes to housing, the UK has its work cut out.

It’s estimated the country needs to be building nearly 350,000 homes every year to meet rising demand – which is a huge step up from where we are at the moment.
We need more housing, more quickly – and that requires the construction sector to become a lot more productive.  But if that wasn’t challenging enough, we have to achieve all that while drastically reducing the built environment’s ecological impact too – both in terms of the construction process, and buildings’ carbon footprints over their lifetime.  That might sound like an impossible square to circle, especially given the rapidly shortening time we have to do it in. It’s only thirty years until 2050, by which time the UK’s committed to reaching net zero.  But it’s possible we’ve been looking the solution in the face for decades and not realised it.

Modular construction
Modular construction is nothing new. Millions of British people, in fact, grew up in prefabricated housing built after the Second World War.
But thanks to enormous advances in technology, modern modular buildings are a world away from the flimsy prefabs of the past – and offer a quicker, cheaper and much more sustainable alternative to conventional brick-built construction.
Modular construction is green because it tends to produce much less waste, and also because whole buildings can be disassembled and used again if necessary.
However, many modular buildings still aren’t as green as they could be – and that’s because very often how they’re heated gets overlooked.
How green are the green alternatives?
If you take a sustainably-constructed building, then fit it with a heating system that’s not environmentally friendly, you’ve not got a sustainable building any more.
In the decade ahead, we’re likely to see a drastic reduction in the use of worst-offending power sources like coal, oil and gas, and the old-fashioned heating systems that use them.
However, some alternatives that look very green on the surface aren’t anywhere near as sustainable as they seem once you start digging a little deeper.
Air-source heat pump technology is often presented as the future of heating, but it’s got significant downsides – they’re very expensive, require specialist technicians to install and maintain, have short lifespans, and in some cases the refrigerant they use can itself contribute to global warming.

 

 

Far-infrared
A much better solution – and one that’s very in keeping with the speed and ease of modular construction – is far-infrared.
Infrared radiation is produced by the sun. It’s measured in microns, with ‘near’ infrared sitting between 0.76 and 1.56 microns, ‘mid’ infrared measuring between 1.5 and 4 microns, and anything above 4 microns classed as far-infrared.
Between 8 and 10 microns, to be precise, is the most beneficial to the human body – and it’s exactly this sort of infra-red radiation that the products we supply at Energy Carbon provide.
Fit it … Forget it
Traditional heating systems work on a convection system. Radiators or electric storage heaters draw cold air from the floor, and heat it so that it rises to the ceiling, where it cools, falls to the floor and the process continues in a loop – which can result in poor air quality, as dust particles rise.
Convection can be slow, expensive, and, often, totally ineffective – all you have to do is open the front door, and the heat escapes, taking you right back to square one.  This mix of hot and cold air can also create moisture that causes mould and mildew, and, more importantly, health issues for occupants.
Far-infrared heating is different. Far-infrared does not create moisture as it is not heating the air. The radiant heat warms objects in the room instead of the air itself.
The objects in turn release their own heat, and the room is kept at a far more even, comfortable temperature. With no convection roll, you get a dramatic drop in the amount of dust particles and or mould, which can alleviate allergen-induced asthma.
Additionally, occupants ‘feel’ the energy themselves, much the same as they feel the warmth from the sun. This feeling of warmth allows the heating to run at around 1-2 degrees lower than conventional heating, thus saving further energy.
The far-infrared solution Energy Carbon provides was originally developed by students at the University of Stuttgart.
They had worked for six years trying to create an energy-efficient heating system which was effective, easy to install, and completely safe.
Using industry waste materials, the students engineered a far-infrared heating system which is sustainable, had great carbon-reducing credentials, and produced radiant heat which could travel up to three and a half metres.
The technology is now widely used across Germany, and over 100,000 linear metres of it have been fitted to date.

What’s more, where alternatives need extra skilled trades and engineers to install and maintain, our heating products are incredibly simple to install into the walls or ceilings of a room, using existing trades and requiring no ongoing yearly maintenance.
Fit it … Forget it.

In short, we think far-infrared is the future of heating in modular construction – and if you’d like to learn more, get in touch with Energy Carbon today.

MTX fast-track ward project in Hereford

After declaring the UK government’s intention to deliver ‘Project Speed’, including a £3billion capital investment into the NHS, healthcare construction company MTX, welcomed the Prime Minister to their latest £12million, 72 bed, fast-track ward project at Hereford County Hospital.

The Prime Minister visited the construction site, keen to see for himself the, now close to completion, ward project aimed to deliver the NHS a total of 72 extra beds across 3 state-of-the-art wards, all in just 11 months.
All part of the government initiative to ‘to build better, to build greener, to build faster’ the new ward extension is being delivered using MTX’s fast-track construction methods that reduce the build time by up to 50%.
Talking on the PM’s twitter feed whilst on site, Boris described the project as “the beginnings of a new series of wards for Hereford County Hospital…. The first of the 20 new hospital upgrades that this government has embarked on….The beginning of a record programme of investment in our NHS’.

 

David Hartley, Managing Director of MTX – “The site team were excited to welcome the PM to our latest project and talk him through the clear benefits of these rapid construction methods. For this project, the building is largely built off-site in a factory, then transported and craned into position. This not only means we can deliver buildings much faster, but we can produce 60% less waste, ensure safer construction sites and all to the same standard and quality as a traditionally built hospital’.
With the Government’s ‘Project Speed’ well underway, described as “the most radical reforms of our planning system since the end of the second world war”, there is also attempts to offset the economic impact of the Coronavirus Pandemic, and the MTX offsite method of construction is leading the way to delivering on Boris’s promises.
MTX are a privately owned, Cheshire based, Healthcare Construction company specialising in the use of innovative, modern methods of construction to deliver fast-track building projects, throughout the UK. With more than 30 years healthcare experience, MTX believe using fast-track methods of construction is the best way to minimise the time spent on site, causing less noise and disruption, whilst still delivering a high quality, energy efficient solution.

Digitalisation as an Enabler to Scale & Leverage Productivity

,

The landscape of the UK’s offsite sector has become increasingly populated over the last few years with many new entrants – mostly concentrated on residential development – joining a host of longer-established players. These new entrants are embracing business models based on the manufacture of volumetric modular residential product, rather than other forms of offsite solution such as panellised product. The investment profile of these new entrants suggests that the success or otherwise of their business models directly relates to an ability to operate at scale and achieve high levels of productivity. A recent report1 has highlighted that investment in technology as well as facilities and equipment is key to securing such lofty ambition, particularly emphasising the importance of digitalisation of both product and process.

Building Information Modelling or Digital Engineering

Digitalisation and the power of data-centricity across the wider construction industry is somewhat misunderstood. Most often, parties tend to think that the creation of 3-D models using common software platforms in order that information can be easily shared and the likes of clash detection carried out constitutes all that is required for the building of an information model. Indeed, over the last 10-15 years, new roles such as BIM Manager and BIM Coordinator have emerged across the industry which tend to reflect this limited understanding. Yet the creation of a geometric digital twin in a virtual modelling environment does not really constitute the building of an information model that digitally captures both the product and the process needed to be executed to create the physical entity.
The newer entrants to offsite who are focused on the manufacture of volumetric modular product for the residential sector appear to lack understanding of digitalisation and the power of data-centricity. For such manufacturing-based enterprises, it is not to say that their utilisation of sophisticated software to foster collaborative working to help the efficient development of a geometric digital twin is not beneficial, rather that in itself it is not adequate for the purpose of facilitating scalability and high levels of productivity.
So, returning to the report1 referred to previously, the digitalisation (or digital engineering) of product and process implies a more wide ranging set of activities than just the collaborative development of a geometric digital twin. Whether these enterprises have implemented rigid manufacturing workflow to support the production of a limited range of standard product, or a more flexible manufacturing workflow to support production of mass-customised products, a data-centric logic which facilitates control of the value chain and supports data-driven decision making is a pre-requisite to success. Plainly, an expansive notion of digitalisation and the power of data-centricity reflects something more than the simple idea of building information modelling, and whilst not widely appreciated it really does hold the key to an enterprise realising scale and high levels of productivity.

Data as the New Oil
In order to comprehend the power of data-centricity, enterprises must secure a deep understanding of what data it needs and how it must flow to efficiently operate, and also how data should be authored, configured, manipulated and managed. Most enterprises do not invest the time and effort to secure the necessary insight regarding data creation and flow. Without this understanding, they are unable to determine the nature of the technology platform needed to support the effective digital engineering of product and process. As a result, they typically default to a technology strategy incorporating a set of software packages which cannot be fully integrated, and so ultimately thwart the enterprise’s ability to exploit the power of data. Furthermore, these enterprises tend to recruit resource into their businesses which reflect the conventional skill sets mentioned earlier, which further limits the enterprise’s potential digital engineering and data-centricity prowess.
Of course, for those construction and offsite enterprises who have made relatively low levels of investment to help harness data, such a technology strategy might not be overly constraining because their direct competition might operate in a similar way realising similar mediocre levels of performance. However, for those newer enterprises that will be manufacturing volumetric modular product for the residential sector and who possess an appetite to operate at scale and leverage productivity, it is likely these will encounter serious challenges and such a technology strategy will ultimately prove to represent a weak link.
As was the case when oil was first discovered, the true power of data is still largely unknown. This is not necessarily a criticism, rather just a statement of reality; and if something does not appear to be a problem then resource is not usually allocated to resolving it. And yet, for a manufacturing-based enterprise that wants to operate at scale and with high levels of productivity, a data-centric focus is imperative.
Accordingly, whilst there is additional investment involved in acquiring the necessary talent into a business and affording the same the time to evolve the appropriate process logic and identify the associated technology platform to fully secure control of the value chain and facilitate data-driven decision making, the long-term benefits are enormous. This requirement for investment can be perceived as a leap of faith compared to capital expenditure on machinery, because the power of data-centricity is not readily understood, and often technology projects fail to get delivered. Nonetheless, the infographic on the left contains some examples of the sort of automated data capture / flow that are required in an enterprise that aspires to be a profitable, high-volume manufacturer of volumetric modular product for the residential sector.

The Need for Discretisation of Data
The power of data-centricity can only be realised if an enterprise has a true, granular understanding of what data is important, what format it needs to be presented in, which resource needs what portions, and what point in time it requires to be created. An enterprise must seek to understand what data it needs and how it must flow to efficiently operate, and crucially how the same should be authored, configured, manipulated and managed. It is only when an enterprise develops a profound insight that it can also start to consider how the authoring, configuring, manipulating and managing of data can be automated. Indeed, for those newer entrants to the offsite sector who want to operate at scale and achieve high levels of productivity, one option often used to compensate for not comprehending the power of data-centricity is to simply employ more resource. Given the fragmented, skills-scarce climate that such businesses might currently be operating in, this sort of compensatory mechanism ultimately remains a limiting factor to achieving scale and high levels of productivity. The rationale behind this is straightforward enough: the skill sets of many of the sorts of people operating across the construction and offsite sectors are not sufficiently broad to properly understand the full idea that lies behind digitalisation. Whilst some of these enterprises might have a fairly advanced understanding of what to build, they are characteristically lacking in terms of their understanding of how something should be built.
The true power of data-centricity can only be realised if data is discretised, that is the packets  of data that are shared between two actors (e.g., from person-to-person, or person-to-machine) only contain information that is relevant to that particular transaction. Any exchange of data which involves surplus, superfluous, imprecise or erroneous information only gives rise to inefficient working because process time is wasted stripping out the unnecessary components of the communication and validating that the remainder is adequate and accurate to facilitate processing. Furthermore, it is crucial to comprehend the importance of data purity and data integrity, so it is essential to create process logic that affords management and maintenance of data sets to avert risk of data pollution. Where data is discretised, such process logic is easier to identify and implement because the size of data packets can be configured to be easier to handle.  So, any offsite providers that can secure control of the value chain and facilitate data-driven decisions is likely to become a sector lead. To summarise, the value to any enterprise of acquiring a granular understanding of the power of data-centricity, including what data is important and how it must flow, is the essence of digitalisation and it is this knowledge that will enable scale and realisation of high levels of productivity.

Fixing solution for externally insulated walls

ETA-approved EJOT Iso-Corner provides assured fixing solution for externally insulated walls

EJOT has secured ETA (European Technical Assessment) approval for its Iso-Corner load-bearing bracket, an engineered fastening element for medium to heavy weight building elements – planned or unplanned – in ETICS and other external wall insulation applications.

The newly awarded ETA confirms the engineered value of EJOT Iso-Corner which is moulded from high density polyurethane foam and can be easily cut on site with an electric saw to sit flush with the external insulation face. This combination of structural strength and adaptability provides a dependable supporting bracket option offering a cantilever arm to length of between 80mm and 300mm.
It is ideally suited to specifiers and installers who need to attach building elements to a façade that is to be treated with an ETICS – external thermal insulation composite systems – or other external wall insulation solution. These could include elements such as railings and Juliet balconies, which require a secure attachment to the load-bearing external wall, the substrate.
Consider the make-up of an external wall insulation system. The insulation is typically attached to the wall structure, treated with coatings and mesh, and finished in the chosen render, brick-slips or other external treatment. The main depth of the system is the insulation board, and whilst this should generally be very securely fixed to the building substrate, it will not have the necessary structural strength to allow for load bearing attachments.
Any attempt to achieve a secure fix by driving through to the original building substrate could compromise the thermal insulation level. Unless a fixing is used that incorporates insulating materials as part of its design, the thermal barrier will be broken, and cold bridging will result. This is one of the criteria of PAS 2035, where it needs to be demonstrated that any cold bridging effects have been designed out of the chosen energy efficiency measure.
Iso-Corner is part of a range of ETICS mounting elements from EJOT designed to achieve safe, secure and long-term fastening solutions in refurbishment projects, including:

•  Iso-Spiral Anchor, a spiral-shaped plastic assembly anchor complete with sealing washer and integrated threaded sleeve which provides a fastening solution for lightweight elements in ETICS facades, such as house numbers and external lights.
•  Iso-Dart – a fastening system comprising of a façade anchor with plastic installation bush, complete with sealing washer, which accepts common coarse threaded screws for securely attaching light to medium loads.
•  Iso-Bloc – an easy-to-cut block moulded from high density EPS, which is particularly suitable as a backing to allow for thermal bridge-free attachments in ETICS applications.

 

As a global leader in construction fastening solutions, the EJOT UK team offers a wealth of technical support and specialist guidance to specifiers and installers to ensure they achieve the right result when mounting to ETICS facades.
For technical support and to find out more about the range of innovative EJOT fastener solutions visit the website, call 01977 687040 – or contact Mark Newell, Sales Engineer for ETICS fastening products at EJOT UK: m.newell@ejot.co.uk

Improving Indoor Air Quality

The global pandemic has forced us all to pay more attention to the air around us, whether in our home, office or outside. Maintaining high standards of indoor air quality (IAQ) is not only important to limit the potential spread of infectious diseases but also to prevent the build-up of indoor air pollutants, such as volatile organic compounds (VOCs), which can significantly impact the health of occupants. One of the simplest and most effective ways to achieve this is by specifying materials which are recognised as low emitters of VOCs under schemes such as the Eurofins Indoor Air Comfort standard.

Understanding VOCs
VOCs can be emitted by a number of materials found in a typical indoor environment, including everything from cleaning products to carpets and paints. The compounds are described as ‘volatile’ as they have a fairly low boiling point. This causes their molecules to become more active at room temperature, allowing them to spread into the surrounding air.
The compounds have been linked with a variety of health issues. Depending on the length and concentration of exposure, these can vary from relatively minor issues – such as dizziness and shortness of breath – to serious impacts including damage to internal organs and the central nervous system.
Whilst an effective ventilation strategy can help to reduce VOC concentrations, it is generally recommended that the first step should be to use materials which are identified as low emitters. The Eurofins Indoor Air Comfort (IAC) programme helps specifiers to quickly and easily identify products which meet these requirements.
Eurofins IAC
The Eurofins IAC has been created to harmonise the criteria within the various VOC emissions standards across Europe. It is split into two levels:
Standard Certification – Identifying that the product complies with minimum mandatory VOC emissions standards within European countries including France, Germany and Italy.
Gold Certification – This recognises the product is also compliant with many of the most demanding voluntary performance standards and can be recognised as being an outstanding material according to the VOC Indoor Air Quality emissions regulations. Eurofins IAC Gold certified products meet the compliance requirements for specifying low-VOC emission solutions within BREEAM, Well Building, LEED and SKA Rating.
In order to achieve Eurofins IAC Gold certification, production facilities are first assessed by an independent inspector who has been approved by Eurofins. The assessor looks at all factors which may affect emissions from the product, such as archival changes in a product’s formulation. During the inspection, samples of products are taken for emissions testing.
Once emissions testing is completed, the results are then sent to the manufacturer along with a detailed report from the inspection, allowing corrective action to be taken where necessary. If the test results suggest compliance and no issues are raised in the inspection report, then the product is issued with certification.

 

Critically, Eurofins requires manufacturers to engage in a process of continuous testing and auditing. Recently certified products are subjected to emission testing and production site inspections every year to ensure low emissions. As a result, installers and specifiers can have confidence that the performance and quality of certified products will be maintained over time.
A growing number of construction products are now certified under the Eurofins IAC Gold programme including Kingspan Kooltherm Pipe Insulation. In addition, work is also under way to consider VOC emissions within the harmonised European Standards for the CE Marking of products.
A healthier future
As we move towards a net zero carbon built environment, our buildings are set to become increasingly airtight. For this reason, the need to control VOC concentrations and to maintain high levels of IAQ is only expected to grow in the coming years. By specifying products which are low emitters, it should be possible to create healthier environments for occupants to live and work.
