At the heart of the transformation was the replacement of over 10,000 m² of out-dated wired glass, bringing the hospital in line with the highest industry standards, while achieving a state-of-the-art, contemporary aesthetic.
As part of the renovation, the decision was made to replace all existing wired safety glass with new, transparent glazing solutions from fire safety glass manufacturer Pyroguard, to ensure that the hospital adhered to current industry standards. This upgrade also addressed long-standing challenges with maintaining accurate product data records for the glass partitions and doors, many of which had been extended or replaced over the years without clear traceability.

At the 2025 Steel Window Association awards, the Supplier of the Year was named as Joseph Ash Galvanizing of Medway in Kent.
Dan Lyons Commercial Sales Manager and Sacha Aarons Sales Account Manager, share insights into the company and the successful relationship with Steel Window Association members.
What is the story behind Joseph Ash?
Joseph Ash founded Joseph Ash Ltd in 1857, and the company has grown significantly with nine UK galvanizing sites trusted to protect the UK’s steel against corrosion.
Joseph Ash Medway (Medway Galvanising Company Ltd) was acquired by Joseph Ash Ltd in 2013, and is home to our one stop shop facility, providing shot blasting, galvanizing, and powder coating all in one place.
How long have you been working with SWA members – which ones specifically?
As a company, we have been working with the association’s members closely for over ten years.
What products, services/processes do you supply Steel Window Association members? What benefits do your services/processes add to the SWA members finished windows and doors?
Our main service across the Joseph Ash Group is hot dip galvanizing, a reliable and proven solution for protecting steel fabrications against corrosion. The enhanced protection against corrosion provided by galvanizing helps to extend steel’s lifespan and reduce its whole-life cost.
Galvanized steel requires little to no maintenance and can last for over 60 years, with documented cases of galvanized coatings exceeding 100 years.
At Joseph Ash Medway, we also have a specialist powder coating facility where both raw and galvanised steel is coated, and we are proud to offer up to 35 years’ warranty on powder coating.

In residential architecture, glazing is often viewed through a binary lens: transparent glass for views and natural light, and opaque materials like concrete or brick for insulation and privacy. But what if there were a third option—one that offered the best of both worlds?
Solera Reserve™, the newest innovation from industry veteran Solera®, brings this vision to life. Drawing on over 30 years of commercial success, the brand is now redefining what’s possible in high-end residential design with translucent glazing units that deliver aesthetics, comfort, and performance—without compromise.
Architects and builders have long understood the tension between openness and livability. Large, clear panes create striking façades and connect residents to nature—but they also invite in solar heat, glare, and reduce privacy. To mitigate this, blinds are installed, which defeat the purpose of transparent glass.
The result is a frustrating cycle: light or comfort, views or privacy, aesthetics or performance. Solera Reserve™ breaks this cycle by delivering uniform, glare-free daylight through high-performance translucent glass panels.
At the core of Solera Reserve™ is patented honeycomb technology housed within double- or tripleglazed units. These assemblies diffuse sunlight deep into interiors, reduce glare, eliminate hot spots, and lower HVAC reliance. With insulation values as high as R25 and acoustic ratings of STC 48, Solera Reserve™ performs well beyond its visual appeal.
The system is meant to be used strategically. Vision glass frames key views, while Solera’s translucent panels support those views— above, beside, or below—ensuring consistent light and thermal comfort without blocking the scenery.
Solera Reserve™ isn’t just a smart building material; it’s a wellness tool. Studies have shown that fullspectrum daylight enhances cognitive performance, reduces hospital stays, and boosts retail sales. In residential spaces, this means better sleep, fewer artificial lighting needs, and more enjoyable living environments.
Moreover, Solera Reserve™ outperforms legacy translucent materials. Fiber-reinforced plastic (FRP) panels, while once popular, are plastic-based, susceptible to UV damage, and often need replacing within two decades. Etched and white laminated glass, though durable, offer low diffusion and insufficient thermal performance.
Solera Reserve™ addresses all these shortcomings—and does so in a way that respects both form and function.
The design flexibility of Solera® is key. Every unit is custom-fabricated, allowing architects and homeowners to define everything from size and shape to glass type, color, and frit patterns. Whether you’re creating a statement wall or a serene living space, Solera®delivers beauty and performance that lasts the lifetime of the building.
Now available through a handpicked network of design-forward dealers, Solera Reserve™ is not a mass-market solution—it’s a tailored offering for projects that demand more.
In an era when performance must coexist with sustainability and design integrity, Solera Reserve™ offers a compelling solution for homes that aim higher.

Independent trade aluminium fabricator Fentrade has recently completed the manufacture and supply of thermally broken Kestrel products for a newbuild facility for Carpigiani UK, a leading importer and stockist of commercial ice cream machines for international fast-food brands.
The newbuild unit, located in Gloucester, will help Carpigiani expand its operational capacity, providing both increased storage space for product and additional office facilities for its growing team.
Working closely with the installer, Fentrade supplied thermally broken Kestrel commercial doors and screens in RAL 7016 Anthracite Grey, meeting the client’s specification for enhanced energy performance. The products were manufactured within the agreed timescale and delivered directly to site to align with the project’s installation schedule.
Chris Reeks, Managing Director at Fentrade, commented: “Thermal performance is now a key consideration on virtually every commercial project. Our thermally broken profiles from Kestrel provide excellent thermal efficiency, which is vital for newbuilds focused on sustainability and long-term energy savings.”
This latest contract reflects the wider upturn in commercial activity that Fentrade is experiencing. Chris continued: “We’re seeing a steady stream of enquiries for projects such as school refurbishments, commercial warehousing, community buildings and office expansions. Our commercial sales are up significantly year on year, which highlights both the market confidence and our ability to deliver to specification and schedule.”
Chris also highlighted shifting customer demands in the commercial sector, noting: “We’re seeing growing interest in colour variation beyond standard greys, as well as more technical hardware specifications. Specifiers are looking for smarter, more secure solutions and want the flexibility to tailor hardware to individual use cases.”
ODL Europe has reported a growing number of fabricators and installers choosing its Capstoneengineered GRP door slabs for their proven resistance against bowing, twisting and distorting, especially in high temperatures.
Suzanne Nicholl, Head of Sales and Marketing at ODL Europe, explains: “As soon as the summer heat hits, we hear the same thing from installers – frustration with alternative composite doors that become ‘bent like a banana’. The callbacks and reputational damage that follows is costly. With ODL Europe’s door slabs, those concerns are eliminated thanks to our product’s inherent structural stability.”
She continues: “Some assume LVL thickness alone determines whether a door will stay flat, but that’s only part of the equation. The real difference likes in the door skin. Doors that warp often have a similar internal construction, but inferior GRP skin composition. Ours are manufactured using high-glass-content GRP SMC skins, pressed to exacting standards for superior performance.”
ODL Europe’s composite door slabs feature 2mm thick impact-resistant GRP skins available in both TrueGrain woodgrain and smooth finishes. These skins are bonded to a high specification subframe made from water-resistant pure PVC polymer and reinforced with high-density LVL (minimum 570 kg/m³). The entire structure is assembled with advanced urethane resin adhesives to ensure complete stability and product longevity.
Each slab is manufactured by Capstone Engineering Ltd, one of the world’s largest GRP door producers and exclusively supplied in the UK through ODL Europe. With over 750,000 doors installed annually worldwide, Capstone sets the standard for GRP durability and performance.
The range includes over 30 door styles, both glazed and unglazed, with several designs unique to ODL Europe. Whether fabricators and installers need traditional, contemporary or modern door aesthetics, the collection is developed to reflect current design trends and give customers a clear point of differentiation.
Leading independent trade fabricator Modplan has further expanded its portfolio with the introduction of the new OMNIA system. Liam Isaac, Head of Sales and Marketing at Modplan, said: “VEKA OMNIA is a pioneering suite of double flush windows and doors, designed to meet increasing demand for flush aesthetics. We showcased the system at the FIT Show this year, and the interest it generated confirmed its standout appeal.”
The OMNIA system delivers a compelling combination of features that distinguish it from standard market offerings. At the core of its design is a zero sight-line mullion, which creates a clean, expansive appearance. For a minimalist finish, windows can also be manufactured using invisible mullions, maintaining the simplicity of the profile.
While OMNIA is compatible with standard VEKA beading, it also offers classic putty and rebated glazing bead options, ideal for heritage or traditionally styled installations. Installers can also benefit from mechanical jointing compatibility, including both Timberweld® and the patented ProJoin Gen 2 technologies.
The system includes a co-extruded PCE gasket within the profile rebate, eliminating the need for manual gasket fitting. This detail creates a subtle shadow line for a seamless finish.
To complement its elegant design, OMNIA supports premium-quality hardware, and a wide range of foil finishes and textured colour options provides further design flexibility.
Naturally, the system meets and exceeds all current building regulations. It also features a click and connect rider block that helps to improve security.
Modplan is manufacturing the full OMNIA suite, which includes casement windows, tilt & turn windows, French doors and residential doors, from its impressive Newport fabrication facilities.
In addition to OMNIA’s design and performance credentials, installers benefit from Modplan’s trusted support package. This includes a reliable in-house delivery service using Modplan’s own fleet, with order tracking available at every stage. The company also offers customised marketing support to help customers drive sales and gain a competitive advantage along with full product training.
Window Warehouse, a leading trade supplier of quality windows and doors, proudly offers DoorCo’s composite doors range. These are manufactured in-house, combining the composite slab with their VEKA outer frame. The style, strength, and security of these doors are built using high-performance materials that are ideal for modern living.
DoorCo composite doors are known for their durability, energy efficiency, and low maintenance. Each door features thermally efficient foam, a multi-point locking system, and Kubu Smart Security integrated, ensuring long-term performance and superior home protection. The doors are tested to PAS 24 security standards and meet current Building Regulations. At Window Warehouse, the manufacturing process takes place at their Portsmouth-based factory, using precision engineering and high-quality components. This ensures every DoorCo door is made to exact customer specifications, with consistent quality and exceptional lead times.

Window Warehouse’s partnership with DoorCo means trade customers benefit from market-leading innovation, including the popular DoorCo Monza II and Links ranges. These designs cater to both new builds and heritage properties, offering strong kerb appeal and long-term reliability.
With competitive pricing, fast lead times, and free delivery, Window Warehouse makes it easy for its customers to offer premium composite doors that meet homeowner expectations.

Hardware supplier VBH has reported an upsurge in enquiries for its greenteQ Invicta Non-Crop outward opening window shootbolt.
As the name suggests, there is no cropping required with the product. The fabricator fits the central gearbox, then, as VBH put it, “they simply drop the correct shootbolt extensions into place before fitting the steel cover plate to hold everything in place before fixing. No marking or cropping is required.”
VBH advise that this non-crop method massively speeds up the fitting time against standard shootbolts, is less messy, and means that the fabricator has no steel offcuts to dispose of.
The extensions feature mushroom bolt / shootbolt combination locking points. These, along with two additional mushroom cams on the gearbox for the centre of the window provide excellent levels of adjustment as well as correct compression along the complete length of the sash.
Gary Gleeson, marketing manager at VBH, says “Invicta Non-Crop is the pinnacle of our Invicta range of shootbolts.
“Being a Q-secure approved product, it offers excellent levels of security and is exceptionally smooth for the end user to operate. But of course, its major selling point is the speed and simplicity of the fitting process, which provide the potential for huge savings in fabrication time. This seems to be resonating with many fabricators just now as, after all, time is money.”
Invicta Non-Crop is available to suit both single sash windows and double sash French casements and is supplied with a comprehensive 10-year greenteQ performance guarantee.
To find out more about greenteQ Invicta Non Crop shootbolts, or any other hardware in the VBH range, contact the company on 01634 263263 or via email at sales@vbhgb.com.
Kenricks has announced that Universal Composite Doors, one of the UK’s leading composite door specialists, has officially signed up as the latest partner for its AK Touch Secure™ smart door lock.
Renowned for delivering exceptional quality and service, Universal Composite Doors has supplied over 30,000 doors across the UK, backed by a 10-year product guarantee. With one of the largest and most competitive ranges in the country, the partnership with AK Touch Secure™ marks a strategic move to further enhance their customer offering.
The AK Touch Secure™ combines cutting-edge smart technology with uncompromising security, offering a seamless upgrade for both new and existing door installations. Designed to work with Kenrick’s 3 Star cylinder, it can be fitted in under three minutes, a major advantage for retrofit projects. This quick and easy installation process was particularly appealing to Universal, whose extensive customer base can now upgrade existing doors with smart functionality.
Dean Human, Technical Manager at Universal Composite Doors, said: “We’ve been looking for a smart locking solution that is both innovative and practical. AK Touch Secure™ ticks all the boxes. Its retrofit capability is a game changer. It allows us to offer our existing customers a smart, secure upgrade with minimum disruption.”

A traditional key override ensures total peace of mind. Through the app, users can also remotely lock and unlock the door, monitor access logs and grant temporary or scheduled access, ideal for holiday lets or service access.
Andy Meakin, National Sales and Marketing Manager at Kenricks, said: “Universal Composite Doors is a highly respected name in the industry. We are delighted to welcome them as a partner of AK Touch Secure™. Their confidence in the product’s retrofit capability and the added value it brings highlights the versatility and strength of this next-generation smart door lock.”
Coventry-based Blinds in Glass Group Ltd has switched on its £75,000 brand new standard toughened glass IGU production facility, and has manufactured 103 units in its first week already. This investment has allowed BiGG to add to its existing range of products which includes integral blinds, glass roofs and composite doors.
BiGG managing director Ian Woolley is focusing purely on producing a quality IGU, eliminating product performance issues that were increasingly causing his customers problems. While many IGU manufacturers compete solely on price –and thereby compromising quality – Ian perceived a real hunger from window companies wanting to buck the trend and concentrate on quality first and foremost, with price reflecting that quality. As a result, he created an IGU brand that stuck to its guns on performance, even if that meant being more expensive.
“We deliver to window companies all over the country, and everywhere we were being told the same story – that they were being let down consistently by their standard IGU supplier,” said Ian Woolley. “Whether it was the level of service, substandard product or scratched glazing, poor IGU supply was negatively impacting their business. The conversations grew into an almost club like environment, in which discussions evolved into what we saw as a gaping opportunity to put together a solution – one that would give our customers that reassurance and reliability that was sorely missing. It is from this that the IGu Club arose, driven by a universal change needed for standard IGUs.”
The new 3000 square foot production facility has been opened at the company’s main head office near Coventry. The company’s commercial focus is on supplying its customers who understand the importance of striving for quality in the supply chain, rather than dealing with the constant headaches caused by substandard products. To this end, BiGG focuses on existing customers who are part of its IGu Club.

How long has the company been a member of the Steel Window Association? And why?
My membership goes back to the early 00’s, when I was actively involved with the Product Development Group. In the early days, my attendance helped me to realise and establish the future hardware requirements for steel windows and doors.

AMC Hospital, which is the largest healthcare facility in the Netherlands, has undergone a major renovation, which has modernised the 1,000-bed facility with a clear focus on enhancing the safety and well-being of staff and patients.
At the heart of the transformation was the replacement of over 10,000 m² of out-dated wired glass, bringing the hospital in line with the highest industry standards, while achieving a state-of-the-art, contemporary aesthetic.
As part of the renovation, the decision was made to replace all existing wired safety glass with new, transparent glazing solutions from fire safety glass manufacturer Pyroguard, to ensure that the hospital adhered to current industry standards. This upgrade also addressed long-standing challenges with maintaining accurate product data records for the glass partitions and doors, many of which had been extended or replaced over the years without clear traceability. By upgrading the glass throughout the facility, AMC Hospital not only enhanced its aesthetic appeal and improved safety standards but also ensured data consistency across the entire site.
MedicomZes, a specialist in hospital construction and renovations, was entrusted with overseeing the project, while Glasdesign were appointed to fabricate and install the glazing systems. Given the scale and complexity of the project –set within a sensitive healthcare environment – MedicomZes approached Pyroguard as a trusted manufacturer with the capability of providing the required quantities of fire-resistant glass, whilst also meeting the hospital’s stringent safety, design and performance standards.
Stefan van Gerven, Pyroguard’s Regional Sales Director, said: “During initial discussions, concerns arose about the compatibility of the existing timber frames with the new fire safety glass and the corresponding load requirements. We collaborated closely with Peutz, a specialist consultant, to test the existing frames as part of a complete system. This is where our extensive library of technical data proved instrumental, as we were able to confirm that the original timber could be retained, with the findings forming a key part of the renovation plans.
“Considering the scale of the project and the volume of glass required, we also recommended a sampling exercise to evaluate the potential glass types that could meet the specified criteria.
