SAFETY BULLETIN: THE ROOFLIGHT ASSOCIATION AND FASET

Rooflight Safety Nets

BE AWARE OF LIMITATIONS AND POTENTIAL DANGERS

A new safety bulletin outlining the potential risks of using rooflight safety nets has been jointly published by The Rooflight Association and FASET, the Fall Arrest Safety Equipment Training association.

Safety netting has played an important role in the construction industry for many years. Usage of nets conforming to BS EN 12631 in underslung applications is supported by FASET as well as HSE (Health & Safety Executive)and ACR (Advisory Committee for Roofsafety).

However, more recently, The Rooflight Association has expressed concern regarding netting products which are being offered for use over rooflights, as a means of fall arrest in the event of a person falling onto a rooflight which may be classed as ‘fragile roof’. Some manufacturers’ installation instructions show nets being secured over out-of-plane rooflights by means of a ratchet strap to the upstand, or freestanding unfixed and unsecured temporary framework.

www.daylightingmag.co.uk

Mark Wilcox, Safety Representative for The Rooflight Association, said: “These practices are potentially a danger to life. Typical rooflight upstands are not designed, tested or attached to the roof in such way as to be able to provide reliable anchorage for a safety net or safey line of any kind.”

Anchorage points for roofwork safety nets must comply with the requirements of BS EN 12632 and BS 8411, and safety lines must comply with BS EN 795 and should be clearly labelled as such.

Rooflights are rarely designed and tested to be used as anchorage points so should not be used for this purpose.

FASET Managing Director Tony Seddon, summed up: “This is an important safety issue which needs to be urgently addressed.

Our ongoing collaboration with The Rooflight Association has resulted in the publication of this succinct bulletin, which provides a clear explanation of the potential dangers to avoid – to help keep roof workers safe.”

The bulletin, entitled Rooflight Safety Nets: be aware of limitations and potential dangers, can be downloaded free of charge from: The Rooflight Association https://rooflightassociation.org/ wp-content/uploads/2024/01/ RA_FASET_SAFETY_BULLETIN_ FALL_ARREST-.pdf FASET https://www.faset.org.uk/ guidance/safety-netting/

EDITOR'S COMMENT

A fast-moving industry

STAYING AHEAD OF THE STANDARDS & LEGISLATION GAME...

The pace of change across the whole construction sector seems to accelerate year-on-year – and the legislators charged with setting standards and parameters are faced with an increasingly difficult job, as technologies evolve and can render standards obsolete in what seems like the blink of an eye.

This in turn places a constant pressure on product manufacturers, designers and specifiers to stay ahead of the game to maintain compliance with increasingly complex and frequently changing standards. The varying requirements of national legislatures add to that pressure.

These issues have come into sharper focus for me recently, through my close involvement with The Rooflight Association – the trade association representing the UK’s rooflight industry.

I see at first hand, the sheer volume of work undertaken by RA and no doubt other trade associations, to provide impartial advice and technical knowledge, to inform legislation and support those subject to it.

This issue of Daylighting Magazine is a case in point, with two articles from The Rooflight Association addressing very different topics affected by complex legislation and its interpretation – or misinformation in some cases.

The first covers the subject of false manufacturer claims in marketing materials, which could lead to non-compliance, or compromised performance or safety. The second highlights a new document issued jointly by RA and FASET, the Fall Arrest Safety Equipment Training organisation, to warn against improper use of safety nets for working at height and giving guidance on safety compliance.

Glazing Vision, another regular contributor to this magazine has also provided an excellent editorial covering the forthcoming Future Homes Standard: another piece of legislation that all in our industry will need to familiarise themselves with.

You’ll also find the usual mix of news, case studies and regular features. I hope you’ll find it an enjoyable, informative read.

If you have any issues you’d like to raise or draw attention to in a future issue of Daylighting Magazine, please email me: paul@daylightingmag.co.uk

False manufacturer claims

PUT MORE THAN JUST COMPLIANCE AT RISK

The Rooflight Association publishes freely available, impartial guidance on rooflight related topics, on its website, including these Quickguides covering thermal regulations for the devolved nations of the UK.

The Rooflight Association is the UK’s trade association representing all aspects of the rooflight supply chain and as such, supports the provision of clear and factual product information to enable the specification of safe and functional solutions.

The tragedy of the Grenfell Tower fire in 2017 and the subsequent enquiry into its causes, as well as other disastrous or potentially disastrous practices such as the widespread use of RAAC in public buildings, have brought into sharp focus the need for clarity and transparency in construction product marketing.

It’s understandable that manufacturers in competitive markets will always seek to present their products in the best light, in respect of compliance – whether with fire or safety regulations, or standards relating to energy performance, structure, longevity or other requirements. However, a line needs to be drawn when through ignorance or deliberate falsehood, manufacturers stray into making false claims.

www.daylightingmag.co.uk

Rooflight upstands & Part L compliance: a recent example Jeremy Dunn, who sits on The Rooflight Association’s Technical Committee, states an example relating to rooflights: He said: “A recent article in Daylighting Magazine presented a manufacturer’s rooflight upstands as being Part L compliant when they are not. It stated that ‘While Part L doesn’t explicitly mandate insulated upstands for rooflights, it does set requirements for the thermal performance of rooflights themselves’. This statement is totally incorrect, as the latest version of Part L, dated 2021, does explicitly require upstands that are not supplied as part of the rooflight to achieve a u-value of 0.35 W/ m2K – see note 7 to Table 4.1 and note 12 to Table 4.2 in Approved Document L1 2021 or note 13 to Table 4.1 in Approved Document L2 2021. This was one of the big

changes regarding rooflights in the latest version of Part L. It’s just one example of a claim which could lead to non-compliant specification, or worse.

In addition to the incorrect guidance regarding Building Regulations, when checked, the manufacturer’s own data sheet showed that the products being referred to did not pin fact achieve the u-value required for upstands and thus the claims they were part L compliant was a false claim’.”

Supporting effective, transparent communication How the rooflight industry presents its product specification information, is a subject that The Rooflight Association places high on its agenda. As a member organisation of The Construction Products Association (CPA), The Rooflight Association supports the aims Winter 2024

IN PROFILE: THE ROOFLIGHT ASSOCIATION

and initiatives of the Code for Construction Product Information (CCPI). This was initiated by the CPA as a direct response to Dame Judith Hackitt’s review of Building Regulations and Fire Safety set up in the wake of the Grenfell Tower tragedy.

To address the findings of her report, the Construction Products Association established its Marketing Integrity Group (CPA MIG) in 2018. A team of marketing and technical experts was brought together, which represented many different types of building materials and experience, as well as representation from government, and some trade bodies.

Leading contractors, developers and housebuilders have recently stepped up to support the CCPI and signed a pledge to work with their strategic suppliers and manufacturers to drive CCPI conformance and raise standards in the industry, as CCPI Demand-Side Supporters.

Issue 38

Best practice starts with clarity and competency Rooflight Association Chairman Ian Weakford contributes to a working stream seeking to develop a construction product competency standard, through the CPA’s Working Group 12, that feeds into its Competency Steering Group.

He said: “The provision of factual, unbiased and clear information about construction products goes hand-in hand with the need for defined competency standards in their specification and installation.

These are key drivers behind much of our work at the Association, through our own and external Working Groups and our member organisations”.

Following its re-brand and reorganisation last year, The Rooflight Association (formerly NARM) represents the UK’s rooflight industry as a whole and welcomes membership applications from contractors, installers, specifiers and consultants, as well as manufacturers of rooflights and associated products. Its mission is to support best practice and to ensure growth and sustainability in all sectors of the industry.

Constructing a

SUSTAINABLE FUTURE

In November, Hambleside Danelaw were privileged to partner with Euroclad Group and Tata Steel Colorcoat in hosting ‘Constructing a Sustainable Future: Industrial & Logistics Buildings Roadshow’.

The aim of the all-day event at the iconic, world class conference facility at Silverstone Race Circuit was to develop the discourse surrounding sustainability in the built environment with a particular focus on buildings in the industrial and logistics sector.

The event featured two guest speakers; first was Tim Ward, CEO from Chetwoods Architects.

Tim focused on ‘Regenerative Design’, homing in on steel and refurbishment. He highlighted challenges such as the disconnect between supply and demand – in particular the fact that, while there are a large number of architects eager to use reclaimed steel, the steel from deconstructed buildings

www.daylightingmag.co.uk

is only available for a short period of time prior to entering the metal recycling stream. He raised the issue that the industry needs to develop a network with clear communication to ensure this steel is reused.

Justin Searle, Technology Director from SPECIFIC, delivered the second guest presentation, ‘Renewable Technology and Integration’, which offered an indepth breakdown of refurbishment options – considering installation of heat pumps and photovoltaic panels. Justin also emphasised the need for data-driven results, focusing on performance monitoring while evaluating previous project solutions.

Alongside these two excellent guest speakers, chairperson Paul Hanratty introduced Gary Southgate, Rhian Blake, and Dave Taylor.

Gary Southgate, Business Development and Specifications Manager for the Zenon GRP rooflight division of Hambleside Danelaw, delivered ‘Sustainability from Natural Daylight in the Built Environment’.

The many recognised benefits of natural daylight and how it can be used effectively in buildings, particularly those in the warehouse and logistics sector, are often overlooked. Gary’s presentation highlighted the importance of the key specification characteristics of rooflight assemblies and how these can affect and reduce the building’s operational and embodied carbon emissions.

Winter 2024

IN PROFILE: HAMBLESIDE DANELAW

Rhian Blake, National Business Development Manager at Euroclad, engaged the audience with the aptly titled ‘Building a Better Future Together’. Speaking about Euroclad’s ‘Planet Passionate Programme’, Rhian identified the Group’s carbon reduction targets through which they have already achieved so much. From plans to fit all three production units with PV panels, to focusing on renewable energy contracts; Euroclad’s ambitions for a sustainable future are clear to see.

The final partner presentation was by Dave Taylor, Business Development Manager for Tata Steel Colorcoat. Dave gave the audience a comprehensive insight into ‘Lowering the Embodied Carbon in Steel Intensive Buildings’.

The methods of decarbonising this energy intensive material were most informative.

Issue 38

Throughout the event, the clear message was that ‘together we make the difference’.

As well as a fantastic lunch, delegates had the opportunity to take in the sights and sounds of the Silverstone racetrack (during a test day, no less!). A panel discussion brought the event to a close.

Hambleside Danelaw had a very rewarding day, with some interesting ideas and forthcoming developments. Working in an industry as collaborative as this one is a privilege – the future of sustainable construction looks bright! (With diffused natural daylight of course!).

CASE STUDY: HOWELLS PATENT GLAZING

IMPROVING

THE ENERGY EFFICIENCY OF OLD BUILDINGS

How do you improve the energy efficiency of an old building?

Building condition has a significant impact on energy bills, carbon emissions, and occupier comfort. Damp and ill-fitting windows and doors, for example, can really affect thermal performance.

10

While regular maintenance and repairs can help optimise building performance and stave off invasive and expensive repair and conservation work, there are some building characteristics which present obvious potential for greater improvement.

In our 50+ years’ experience, we have encountered several worthwhile solutions – insert sympathetic and appropriate double glazed units or add secondary glazing. With old buildings however, it is often not as simple as this, and a bespoke solution is required.

Most sloping glazing and old roof lanterns and lights are single glazed, for example. Not only is it easier to shatter a single pane of glass but single glazing can cause issues with heat loss and condensation which leads to increased energy costs.

Guidance from Historic England In a document produced by Historic England entitled Energy Efficiency and Historic Buildings – how to improve energy efficiency, replacement glazing is categorised as a ‘red’ action to improve thermal performance – it is a high-risk and high-cost option and careful consideration is needed.

www.daylightingmag.co.uk

‘Single glazing can be replaced with double glazing, but unlike secondary glazing, this will not directly reduce draughts or heat transfer through the frames, it can, however, be combined with draughtproofing.’

Historic England also highlights that ‘metal frames are cold bridges and are especially likely to attract condensation if reglazed with insulated glass units.’

The key consideration is whether the glazing makes an important contribution to the significance of the historic building. ‘…usually very Winter 2024

CASE STUDY: HOWELLS PATENT GLAZING

neglected windows can be brought back into condition relatively easily and upgraded with systems such as secondary glazing’.

Bridlington Town Hall This was the approach we adopted for the Grade 2 listed Bridlington Town Hall. We completed three glazing areas, including two pyramid rooflights designed to sit over a pair of original domed lanterns.

The new rooflights provide valuable protection for the glass domes.

Tested for both weathertightness (BS 6375 Part 1) and Resistance to snow and permanent load (EN 14351) they are a far more robust solution than secondary glazing.

They are fitted with 28mm double glazed units which aids thermal performance but by sitting these within a modern aluminium structure – using our thermally broken HG2 and HG3 self-supporting patent glazing system, we can avoid cold bridging and support the overall energy efficiency of the building.

Skill and Experience Working with historic buildings requires skill, patience, and often, lateral thinking. There is rarely an off-the-shelf solution. It is why we are chosen to work with organisations like English Heritage, National Trust, and custodians of some of Britain’s most spectacular and historically important buildings to design and install bespoke roof glazing solutions.

The company was started by Walter Howells more than 50 years ago, since then we have gained a reputation for delivering high quality products and service. We provide a supply only and a supply and install service. Often, those

clients working on historic buildings choose the latter as they trust in the skill and expertise of our fitters and know that we will deliver the very best possible job.

Our experience isn’t just in the design and fitting, it’s also our awareness of the risks associated with old buildings. Most notably, asbestos. In old roof glazing systems, the grease cords within the gaskets may contain asbestos and these need to be independently tested. Our installers have asbestos awareness and unlicensed removal training. If when tested (which is often done independently through a local testing site) the asbestos falls below a certain grade our installers can remove it. www.howellsglazing.co.uk

How rooflight specification can help deliver the

FUTURE HOMES STANDARD EARLIER

High-quality residential developments are no longer defined only by their location and standard of finish. Stunning architecture, luxurious interiors and high-end amenities are still expected, of course, but there is something else to add into the mix: sustainability.

A new home or high-rise development doesn’t have to be labelled as an “eco home” to be part of the sustainability conversation. Whether driven by the client, the architect, or the two working in collaboration, better standards of energy efficiency and comfort, along with healthier interiors, are now normal aspirations.

The blank canvas of a new project offers the opportunity to deliver much more than the minimum standards required by building regulations. Project teams now routinely look to the promised Future Homes Standard – not due to be implemented until 2025 – as a benchmark for performance.

12

www.daylightingmag.co.uk

As a component of the building envelope that must balance energy efficiency with providing natural light and views out, rooflight specification plays a big part in whether that benchmark is achieved. Future Homes Standard will mean healthier homes. This is good news – but why wait – Rooflights can support healthier home specification today.

What is the Future Homes Standard?

The Future Homes Standard is the name given to proposed changes to the Building Regulations in England, expected to take effect in 2025.

It is not one single standard or document, but the combined result of updates to Part L (conservation of fuel and power), Part F (ventilation)

and Part O (overheating), as part of the wider Building Regulations.

The current stated intention of the ‘Future Homes Standard’ is for new residential properties to deliver an average reduction in carbon emissions of 75-80% compared to Part L 2013. Thanks to such significantly better performance, homes should not require energy efficiency retrofit measures in future.

The eventual decarbonisation of grid electricity will account for the remaining operational emissions, meaning new-build homes will play their part in helping the country to meet its legally binding net zero carbon targets.

Winter 2024

IN PROFILE: GLAZING VISION LTD

Do we know the actual requirements of the Future Homes Standard?

The short answer to this question is: no.

As of October 2023, we only know the intended implementation date, and the desired reduction in carbon emissions that the Building Regulation changes should deliver.

A consultation on the technical detail of the changes is imminent – in theory.

Earlier government timetables identified 2023 as the date for seeking the construction industry’s views. But will that timetable be met? We are writing this at a time when the Prime Minister has rolled back several policies aimed at delivering net zero.

Measures critical to meeting 2050’s target have been delayed, severely denting business planning and generating a lot of uncertainty at a time when certainty is needed.

So far there is no indication of a change to the Future Homes Standard timetable, but would any of us be surprised if it was subject to a delay?

How can projects be built to the Future Homes Standard today?

Until it is consulted on and agreed, we don’t know the precise technical detail of the Future Homes Standard. However, there are two key elements that make it possible to deliver a new residential development today and claim alignment with it.

The first is the knowledge of the intended carbon reductions.

A development can be assessed against the version of SAP used by the current Part L 2021, with improvements made to the specification such even greater carbon reductions are demonstrated.

The second element is Part L 2021 itself. The government introduced Part L 2021 with the specific intention of it acting as a Issue 38

stepping stone to the Future Homes Standard. It lays the groundwork for increased uptake of heat pumps, and the general electrification of properties, alongside much better building fabric standards.

These will all be features of the eventual Future Homes Standard.

Specifying rooflights to deliver Future Homes Standard levels of performance Despite uncertainty around broader government policy, businesses are pushing ahead with their plans to help deliver net zero.

The construction industry is no different, and projects are routinely looking to achieve performance above and beyond Part L 2021.

Part of that is sensible risk management. Planning a project now to current regulations, only to find it then needs to meet the Future Homes Standard in just a few years, would require substantial changes to the specification.

Much better to work to that specification now and create healthier, more comfortable and more energy efficient homes.

High standards of building fabric performance, supported by low U-values and correct installation, are essential for meeting current or future regulations. Rooflights are part of the building fabric, so choosing high-quality components from a reliable manufacturer is essential.

Rooflights have always played an important role in homes.

They can provide a level and quality of daylight that facade glazing alone struggles to replicate.

Better levels of natural light are good for the health and wellbeing of building occupants and can reduce reliance on artificial lighting – thereby saving energy.

With greater focus on sustainability, installed rooflights must deliver the right thermal transmittance (U-value), solar transmittance (g-value) and, where required, ventilation to support the overall energy efficiency and comfort goals.

That is true whether choosing from an existing range or having bespoke items created to fit a particular architectural vision.

Rooflights also must be capable of being installed within the surrounding roof, without creating a break in the thermal envelope and causing significant thermal bridging. Thermal bridging heat losses risk undoing all the intended performance goals for the dwelling as a whole.

And with overheating now a part of the Building Regulations, rooflights can play an even greater role.

Alongside delivering daylit interiors, impressive views and desirable architecture, they can be positioned to limit solar gains. Their potential to provide natural ventilation might also be an answer in situations – such as high-rise developments – where achieving cross-ventilation through a property is not possible.

ISO Chemie’s WINFRAMER specified for

MK RESIDENTIAL WINDOW UPGRADE

ISO Chemie’s WINFRAMER thermal insulating and load bearing bracket support system has been specified for a housing refurbishment programme in Milton Keynes.

ISO Chemie’s thermal insulating and load bearing bracket support system has been specified for a major South East housing refurbishment programme.

The move sees dozens of WINFRAMER units being retrofitted

by Sandy-based Potton Windows on pre-fabricated residential properties on a Milton Keynes housing estate over the next two years as part of a window upgrade investment project. The use of WINFRAMER will help to provide improved standards of thermal insulation, eventually bringing the properties up to zero carbon ready standards and delivering energy efficiencies for home owners together with longterm cost savings.

16

The Potton Windows Milton Keynes project comes as a wider Government strategy continues to push to reduce carbon levels in housing that has single skin, cavity or non-cavity walls - these buildings have a reputation for losing considerable amounts of energy, heat and sound.

Passivhaus certified and fire rated to up to 30 minutes, WINFRAMER is a prefabricated installation frame, manufactured to accommodate cavities up to 250mm that allows windows to be supported independently from the face of the wall regardless of any external cladding being in place.

Tom Ray, contracts manager at Potton Windows, which manufactured and installed the original windows back in the late 1980s and is now replacing them supported by ISO Chemie’s sealing technology, said: “As window system designers and developers, we are always looking at smarter ways to deliver low carbon units.

ISO Chemie’s fit and forget products offer solutions for effective window sealing, delivering measurable airtight, acoustic and thermal sealing benefits in the process.”

Quick and easy to install, the product’s application alongside the new window units is already reaping benefits for some homeowners, who are seeing a reduction in their heating usage with ‘huge’ energy cost savings.

Andy Swift, country director at ISO-Chemie, said: “As new building regulations continue to bite, property owners and window contractors require smarter ways to deliver refurb projects through sustainable technologies.

www.daylightingmag.co.uk

By working in partnership with ourselves, we are helping Potton create high-performance windows with a highly efficient installation.”

The composite WINFRAMER brackets can bear heavy windows loads, including bi-fold doors, to provide a reliable, strong and highperformance support frame.

Installation is quick with windows attached directly and secured mechanically using either standard fixing screws or fixing lugs in the usual manner.

A hinged insulation core combines with the composite wood structural bracket to become an integral part of the overall wall structure, providing compliance with window energy saving regulations (EnEV) and the RAL quality assurance association.

ISO-Chemie is one of Europe’s main producers of impregnated foam sealants.

CASE STUDY: WHITESALES

Birmingham Museum and Art Gallery Project: Birmingham Museum and Art Gallery Client: ISG (Contractors) & Birmingham Museum and Art Gallery Scope of project: Replacement of original timber rooflights in a Grade II* listed building overlooking the city’s landmark Chamberlain and Victoria Squares.

One bespoke Monopitch rooflight with vertical front face and sides set at 350mm two bespoke lantern rooflights with sides set at 440mm and 450mm.

The Challenge Built in 1865, the Birmingham Museum and Art Gallery has long housed treasures from the likes of Edward Burne-Jones, William Morris and Dante Gabriel Rossetti and has an unrivalled 2,000 piece Pre-Raphaelite collection. However, it closed in November 2022 for essential maintenance which included electrical work, upgrading of the heating, lift replacement and roof repairs.

New rooflights are a key element in those roof repairs, so the challenge for Whitesales was to supply and install high performance, energyefficient replacements for the timber originals which satisfied the constraints of the Grade II* listing and met the requirements of the City Council’s conservation office.

Once the design and specification had been agreed for the historic building, the rooflights also had to be fabricated and safely delivered to site in manageable-sized elements because access in and around the city centre site was difficult.

Issue 38

The Solution Whitesales worked closely with contractors ISG on the specification and design of the new aluminium rooflights. We visited the site for a survey, attended design meetings and delivered a sample to the site so that everyone on the client team was happy with what we were supplying in terms of both performance and aesthetics.

The finished rooflights are all bespoke. One is a 2610mm x 1260mm Monopitch rooflight with vertical face and sides set at 350mm. The other two are lantern rooflights of 2400mm x 2000mm and 3730mm x 1650mm with verticals of 450mm and 440mm.

They are all finished in an anthracite grey on the exterior and white on the interior and are all CWCT TN92 Class 2 non-fragile to ensure the safety of anyone walking on the roof.

The Benefits Whitesales has a long standing relationship with ISG, based on the quality of the work we have carried out on previous. For ISG’s Trainee Construction Manager Ryan Linnecor, Whitesales impressed with our knowledge and experience on heritage schemes.

He commented: “Whitesales had a clear understanding of the Grade II* listed scheme and the constraints that presented. They impressed us once again with their approach on how to undertake the work sympathetically and the finished installation is of a very high quality.”

The clients at the Museum have already commented on how the new rooflights are bringing new natural light into previously dull areas of the building, something which will be appreciated by visitors when the Museum and Gallery starts to reopen in 2024.

DAYLIGHTING ICONS

The Hearst Tower, Manhattan, New York In this regular feature we indulge ourselves and our readers with images of daylighting projects throughout the years that simply deserve a double page photograph...

When Norman Foster’s Hearst Tower was completed in 2006, it became the first office tower in New York City to be certified LEED Gold by the U.S. Green Building Council for both its core and shell as well as its interior fit out. It gained this distinction in part, for its use of daylighting controls.

Of the tower's 46 floors, two employ daylight dimming systems at all perimeter spaces. The rest of the office floors were outfitted with daylight switching systems on the east face, where there is a 5-foot-wide circulation corridor abutted by open workstations.

Unlike dimming systems, which use sensors to adjust electric light levels in balance with the amount of natural ambient light, switching systems keep the electric lights off when sunlight is present, and turn them on when sunlight disappears.

We saw an opportunity to work more closely with the Association’s manufacturer members and to gain deeper insights into the many factors which affect and influence our industry.”

Ian Weakford, Chairman of The Rooflight Association, said: “It’s great to have a forward-looking business like GeoRoof as a new member company – we’re delighted to welcome them and look forward to working together.

Previously, as NARM (the National Association of Rooflight Manufacturers), our membership was limited to manufacturers only.

We now welcome applications from contractors, installers, specifiers and consultants, as well as manufacturers of rooflights and associated products – to provide a united voice for the whole rooflighting industry”.

Rooflight Association member companies undergo a detailed audit prior to acceptance, to ensure quality and compliance with relevant standards & legislation.

Both Karl Grandfield and Piers Whites from the Whitesales’ Fenestration Sales team will be getting behind the wheel. Karl said: “The Truck will massively enhance the customer experience – it’s not just about taking the ‘products to the prospects’, it’s also a good way for us to deliver face to face demos and training.

Featuring fully assembled versions of both the Whitesales em.glaze flat glass electric rooflight and the em.glaze Skyvu lantern, the truck gives customers the chance to get really hands on with the products and see the quality and operation for themselves.
