"glazing"

With views overlooking central Manchester from several floors up, the designers for this workspace have utilised glazed partitions throughout to maximise the transfer of light and make the most of the stunning backdrop offered by the city skyline.London Wall was approached to provide a glass moving wall system that could seamlessly integrate in to the overall design of the space by matching the proposed glass partitions, while offering space flexibility.Our Type G200 system was the perfect choice, with a crittal effect indention to the static panels on show elsewhere within the space. The glazed panels can quickly and easily be stacked, allowing staff the choice between a single, large open plan space or two smaller spaces.When the panels are in use, the two spaces both remain easily accessible thanks to a lockable pass door. Type G200’s impressive acoustic performance ensures that sound transfer between the two spaces is kept to a minimum, therefore reducing noise distraction and increasing privacy.

The IQL in the International Quarter (TIQ) is London’s most dynamic and innovative business neighbourhood. A destination where people and organisations come together to encourage creativity, promote curiosity and embrace change for good. The TIQ area covers fully occupied buildings and have glazed-in DucoWall 20V louvres installed, combining intensive ventilation with an aesthetically pleasing design.

Meeting a quartet of criteria, Kawneer’s AA®110 SSG (Structurally Silicone Glazed) and AA®100 capped aluminium curtain walling almost completely wraps the new £25 million Citylabs 2.0 development within the Oxford Road Corridor innovation district in Manchester, at the gateway to Europe’s largest clinical-academic campus.

EH Smith worked with CZWG Architects to develop a bespoke mauve coloured ceramic rainscreen. We are able to match any RAL colour in glazed tiles, so the exact colour that was desired was achieved.We were also able to work with the specialist contractors on the project to design a bespoke engineered support system to accommodate the unique geometry of the façade.

Grimsby based fabricators Fabrique Specialist Glazing were a perfect choice to complete all the fenestration needs for a brand new Holiday Inn Express in Grimsby Town Centre. Fabrique approached their aluminium supplier Kestrel Aluminium Systems to assist them with the project and the two companies worked in partnership for the entire project, from product specification to delivery.

MODERN COASTAL ARCHITECTURE CREATED USING TECHNAL SYSTEMSLayered recessed glazed facades, created using TECHNAL aluminium systems, maximise occupant views and deliver a sleek seafront architectural focus for new, luxury apartments overlooking the beach at Gorey in Jersey.Designed by Jersey-based Morris Architects, the development called The Beach comprises six apartments across four floors with undercroft car parking. Constructed by main contractor, Camerons, the glazing package was coordinated by installer Style Windows who worked with fabricator Bonam and Berry Ltd to develop the specification. “Using layered glazed balconies and recessed facades, the building takes on a stylish streamlined appearance. A sweeping corner provides an open, translucent structure, which minimises impact on the adjacent cottages and the beach. Secondary vertical columns have been used to help articulate the horizontal curved form of the balconies.”Ricardo Marques, architectMaximising the beautiful view for the building’s occupants using minimal profiles was a priority for the design team, without compromising the façade’s weather performance at this exposed location. This was achieved using a range of aluminium systems from the extensive TECHNAL range.  For easy access to the balcony area on the seaside elevation, the TECHNAL C160S Lift & Slide aluminium door system has been installed to each level, combining minimal sightlines and high thermal performance with a user-friendly slide action that glides, effortlessly. One of the door sets is an impressive 4.5m wide x 2.4m high, comprising only two panes, both of which are sliding. "Coastal developments always require a diligent approach to glazing specification. The architect had a clear vision for the building and the facade required a precision specification to achieve the right balance between aesthetic and performance in relation to the building's exposed location. Whilst installing beach-side was challenging, the finished facade looks impressive."Dave Sutcliffe, Style WindowsTo achieve the curved glazed corners at each storey level, TECHNAL Elegance 52 ST Curtain Walling has been fabricated to the specified quadrant, with an external radius of 1.9m, resulting in an impressive glass arc width of almost 3m. Combined with the 2.4m floor to ceiling height, the Elegance 52 ST system has allowed for a truly breathtaking sweeping curve to the building. Internally, the mullion of the curtain walling aligns perfectly with the adjacent Lift & Slide doors, giving the façade an elegant, continuous flow across the elevation."This is the beauty of TECHNAL systems. Even with the high wind loads of this exposed location, we have been able to create a sleek facade solution."Ricardo Marques, architectOther TECHNAL systems used on the project include four single doors and one double-set from the Dualframe Dualsecure 75mm range as well as its STII Doors to the entrance and escape doors. A selection of Dualframe 75mm SI windows in top hung, side hung and pivot configurations have also been installed throughout the building.Taking advantage of the dual colour facility and to combat the extreme weather conditions of this coastal location, externally the systems are anodised to Anolok™ Umber 543 in contrast with the white rendered walls. Internally, a white powder coat finish has been used to maintain the light bright design inside the apartments.To the north facing elevation, standard low-e toughened glass was specified with the rest glazed using solar control glass."Bonam and Berry has supplied TECHNAL architectural aluminium products continuously for over 40 years, and uses the complete range of systems for residential, commercial, educational and all public and private sector applications."Andrew Spencer, Commercial Director at Bonam & Berry

The Ashington Leisure Centre is a community and leisure facility that sets a high benchmark and precedent for design excellence, marking the beginning of a regeneration for the town centre. Externally the building stands with civic pride facing the town centre. The scale of the large volumes: the triple height entrance foyer and pool elevation are fenestrated with tall glazed panels bringing elegance and emphasis to the entrance area.

Bruyn’s Court is an architecturally innovative scheme comprising 25 apartments for over-55s wishing to downsize to a property which can also adapt to changing physical needs. The development, which features VELFAC glazing and doors throughout, was described by RIBA as ‘a positive landmark with the potential to kick-start a new era for the locale’, and won a RIBA National Award in 2016.

Working in close co-operation with the building envelope and façade contractor Colorminium, Metalline have produced a range of bespoke 3D twisted fins that will when complete take centre stage on the exterior of the redeveloped Minories Hotel in the City of London. This stunning feature was the brainchild of ACME architects who in collaboration with The Murphy Façade studio have designed a series of full storey aluminium fins that clad the existing precast frame and create a bridge between that and the unitised glazing. Fabricated offsite at Metalline’s state of the art manufacturing facility in Cannock, these 42 metre height fins were produced in 3.5 metre lengths with a depth of over 800mm. Manufactured in 2 parts, each element was assembled using a combination of aluminium stud welding and bonding techniques developed by Metalline. The fins were then fitted to the glazed panels using an aluminium bracket support system to ensure structural integrity. Finished in dark and light bronze PPC to mimic an anodised effect, the fins will create shading for the hotel’s occupants as well as an iconic architectural vista for this stand out landmark project.

Completed in 2020, One Braham, designed by Wilkinson Eyre, delivers 18 storeys of Grade A office accommodation aimed at tech, telecoms and media clients.The 20,000m² fully-glazed unitised facade, installed by Focchi Spa, combines AGC Stopray Vision-50 and Stopray Smart energy efficient coatings together with vertical brise-soleil on the east, south and west facades.

Installing a lift in a top floor apartment must not compromise the stability of the building. The installation of residential lift Cibes A5000 has minimal structural impact and requires very little construction work compared to a conventional lift. The lift shaft of the Cibes A5000 can be glazed on all sides, including the machinery side. Glass looks fantastic and preserves the light and airiness of the space.

Local aluminium fabricators and installers Atcost Windows of Llanelli won the contract to supply and fit all the glazing products throughout the building. Kestrel’s curtain walling was specified to create an impressive frontage to the building and maximise natural light to the common areas and meeting rooms.

Energy Efficient Heritage Windows for a Victorian RetrofitThe retrofit of Mews House, a low-energy Victorian listed mews property in West London, showcases how heritage windows can be utilised in a retrofit project to enhance energy efficiency while preserving the building's character and historical features.A Conservation Area GemBuilt in 1878 as a traditional carriage house with stable doors, Mews House was later converted into a residential property. However, over time, it suffered from poor layout, inadequate heating, and tired exterior facades. Architects Prewett Bizley undertook the challenge of transforming the interior into a light-filled open-plan living space, improving the property's external appearance while adhering to the local conservation area guidelines, and significantly reducing its carbon footprint.The Role of Winston Sliding Sash WindowsReplacing the existing single-glazed windows with Gowercroft's Winston Sliding Sash windows played a vital role in achieving the project's sustainability and conservation objectives. The architect required windows with higher performance levels, including superior thermal efficiency and a traditional timber aesthetic that matched the original "multi-pane" windows, which was crucial for securing planning permission. A total of 16 Winston Sliding Sash windows of various sizes were installed, featuring traditional joinery elements such as glazing bars, fitch fasteners, pulleys, and concealed gaskets, creating an authentic appearance.Energy Efficiency and AchievementsThe use of vacuum glazing in the windows provided excellent energy efficiency, achieving an overall U-value of 1.5 W/m²K, with the potential to reach even lower values in future iterations. The air tightness of the frames, coupled with Gowercroft's sealing system, contributed to an impressive air tightness rating of close to 1 m³/m²hr at 50Pa, surpassing expectations for a property of this kind.The retrofit of Mews House resulted in an astounding 82% reduction in overall energy consumption, bringing it below the 2025 RIBA targets for new build houses. The replacement sash windows played a pivotal role in achieving this energy reduction, both through their U-value and by minimising air infiltration.Bob Prewett from Prewett Bizley expressed his satisfaction, stating, "What's amazing when people visit is that they are totally convinced the windows are original and single glazed."The successful integration of energy-efficient heritage windows in the Mews House retrofit sets a new benchmark for heritage preservation combined with sustainable design and demonstrates the potential for revitalising older properties to meet the energy standards of new builds.

450 sash windows restored and double glazing installed by ventrolla at royal academyKEY FEATURES: COMMERCIAL, GRADE II LISTED, SASH WINDOWS, EDUCATION, RENOVATION, DOUBLE GLAZING, VENTROLLA PERIMETER SEALING SYSTEM, VICTORIAN.After the existing windows, dating back to 1862, were given their marching orders due to their poor condition, the timber renovation specialists were drafted in to upgrade the ageing sashes.As part of a £7.5 million refurbishment across two years, the Grade II listed building, used by the Army Medical Directorate, presented 450 sash windows in dire need of  complete renovation and upgrade due to many years of exposure to the elements.The majority of sashes were one and a half metres tall with larger ground floor windows reaching two and half metres.The deteriorated condition of both the sashes and frames meant the building was very draughty with many of the windows being rotten and inoperable.To remedy these problems the rotten timber was routed out of the original box frames, and replaced with Ventrolla’s patented epoxy resin VR90. Preserving the original sash windows was just as important as improving the energy efficiency of the building.Following this process, the unique Ventrolla Perimeter Sealing System (VPSS) was installed to combat draughts and reduce external noise. The sash cords were then replaced, pulleys serviced and sashes correctly balanced to ensure the smooth and safe operation of the windows. Andy Meachen, Project Manager of the Military Academy, said:“The service that Ventrolla provided was excellent and we were very pleased with the final result. We have really benefited from the renovation work as the building is noticeably warmer, there are no more draughts and the windows now open easily.”“We were very concerned about maintaining the aesthetics of the building and being sympathetic to its heritage, Ventrolla managed this beautifully.”“Due to their professionalism and craftsmanship, we have also asked them to start work on our Old College renovation project too.”The Royal Military Academy, Sandhurst was founded in 1947 and offers military, practical and academic training.With over 30 years experience, Ventrolla offers a tailored range of period window solutions. Their unique service includes draught-proofing with the Ventrolla Perimeter Sealing System (VPSS) and fitting replacement double-glazed sashes that incorporate the patented Sash Removal System (SRS) for easy painting and future maintenance.They also offer complete new timber windows, secondary glazing solutions and a wide range of window hardware. Ventrolla has its head office in Harrogate, North Yorkshire and regional offices located throughout the UK and Ireland.

The monument, sited on a roundabout on Avenida Circunvalar, near the city’s industrial area, uses a huge steel and aluminium frame to support more than 2,000 m2 (21,500 ft2) of colored laminated safety glass. Arranged in a harlequin pattern, the glazed panels - in shades of red, yellow, green, blue and white - cover the entirety of the structure in a multi-colored façade that is both complimentary and contrasting to the surrounding area.

Prior Weston Primary, located in the City of London, required a large south facing free standing canopy that would create solar energy for their school whilst also protecting their pupils from the elements. Able Canopies designed and installed a variation on the Kensington Dual Pitch, incorporating IPV (Integrated Photovoltaic) solar glazing panels into the roof panel design to provide a solar power facility for the school.

The £15million new Tarka Leisure Centre in Barnstaple, was designed to link with the existing Tarka Tennis Centre. There is now a natural flow between the existing and new part of the completed facility. Sport England invested £1.8m of National Lottery funding into the development of Tarka Leisure Centre to support the ‘get active’ initiative by making the facilities accessible and inclusive for the local community. The new centre, officially opened by British Winter Olympics hero Eddie ‘the Eagle’ Edwards, provides a much-needed swimming pool facility, an ‘endless’ indoor ski slope facility, a sports hall with four badminton courts, a large gym, two multi-purpose exercise studios, a spin studio, indoor soft play area, new reception area and café.With leisure centres having a high footfall and being a naturally noisy environment, it was paramount to consider the fire safety and acoustics of the building.  Lusso 105FR, a double-glazed fire-rated system, which provides acoustic performance of up to 54dB and fire performance of up to 60 minutes integrity and insulation was the ideal choice for this environment. Lusso Structural Glazing was installed where a higher specification level was required for edge protection.

Metalline’s glazed in Ultima aluminium insulated panels have provided a specialist touch to the recently completed Weybridge Business Park in the Borough of Runnymede. The commercial office park features a number of office buildings that have been refurbished as part of a redevelopment for Standard Life Investments. The bespoke glazed in panels which feature on the window surrounds to the 1st and 2nd floors were coated in PPC golden beach metallic and feature a fluted design that met the architects vision for the external envelope of the building. The aluminum outer face was fitted with extruded box sections to give the fluted appearance. The aluminium section was then sealed using specialist rivets designed by Metalline for this specific application. Each of the 2 metre panels were then vacuum bonded using Metalline’s new 6-metre vacuum bonding press. Ultima panels are traditionally specified in aluminium with either an anodised finish in natural silver, bronze, black or blue-grey or in a range of polyester powder coated RAL and metallic colours. They can also be provided with a noncombustible A1 fire rated core. Alternative facings such as perforated aluminium, stainless steel or can be incorporated to create a truly bespoke panel.

The ChallengeMade up largely of two 19th-Century coal warehouses, the site needed to be drastically re-thought to evolve into a new retail complex comprising more than 50 shops and restaurants.With high levels of footfall anticipated, the safety of individuals would need to be a primary factor in its redesign.As well as this, creating light-filled spaces to attract shoppers from across London would be integral to the project’s long-term success.As a result, specifying materials capable of balancing safety requirements alongside aesthetics and practicality was critical.The SolutionSupplying in excess of 150 square metres of Pyroguard Protect toughened fire-rated glass to various classifications – including E60, EW120, and EI60 – to the project, Pyroguard was able to fulfill the architect’s safety requirements, while delicately balancing the need for aesthetic excellence to contribute to the repurposing of these historic buildings.Working closely with Propak Architectural Glazing who were enlisted to design, manufacture and install a large range of steel glazing systems for the project, Pyroguard created a bespoke thickness of 31 mm, instead of the traditional 25 mm for the EI60 requirement, to perfectly complement the systems.

The 2022 Stirling Prize was won by Niall McLaughlin Architects for the Magdalene College Library in Cambridge. The exterior of the building combines glazing, timber, brick and an elegant QUARTZ-ZINC PLUS standing seam roof using the BBA certified Structural roof, which is a warm roof (non vented) system. The roof was installed by a VMZINC@WORK partner, All Metal Roofing thus making a 50 year warranty possible.

The Hepworth Gallery required access to their low pitched roofs to facilitate safe working at height when carrying out external glazing cleaning and general maintenance. The concrete design of the building resulted in a thin roof construction, so The Gallery needed to ensure that any systems installed were fit-for-purpose, fully tested and compatible. With such a prestigious and architecturally prominent building, it was imperative that the chosen system also suited the design of the building.

Austin Smith-Lord’s 50 million–pound Liverpool Central Library project opened in May 2013 after a three–year complete overhaul. The scheme, in a World Heritage Site, involved the restoration of grade I listed elements as well as the insertion of a new building behind a historic facade. It was funded by PFI. The six-storey new building is arranged around a full-height atrium crowned with a glazed dome and roof terrace.

Project description: 8 skylights - Repair and Re-glaze in Georgian wired obscured glass.The units were in an awful condition as you can see from the pictures, showing extensive rot. All of them were stripped back to bare wood, the putty removed and glazing taken out. We then used a Sadolin Super Dec in white to bring in the parts under the window and replaced the hooked with more tradition lead ones.  Once puttied, we removed the tape as to give it the best possible line before it dried (Timbabglaze is normally paintable after just 1 hour). Once dry we re-masked and used a Dulux UK weathershield system. This was a supergrip primer, oil based Dulux weathershield under coat and finally 2 top coats of Dulux weathershield gloss. The tape was removed and you have the finished product for the first 6 windows.The last 2 windows proved to be a problem. They had been re glazed previously but had been done very badly. The wood was rotten and had to be repaired. After struggling to get the glass out as it had been silliconed in... We used Timbabuild products again. To start with we raked out all the rotten wood back to a hardish part. We then used a Timbabuild 2 part EWS wood primer to give the wood some structure and a base for the next part. Once the EWS had gone off we applied Timbabuild EHB60 epoxy repair. This was left over night (as it was applied last thing in the day) and sanded back to an edge the following day. We then used the Timbabuild ERC10 Rapid curing epoxy adhesive over the top to fill any gaps that needed it. Then a surface layer of 2 part Timbabuild FINISH. They were sanded using a 180 grit paper and received the same paint system as the other 6 windows. The glass was replaced as well as the hooks and the finished results speak for themselves. 

Based in Somerset, Taunton School was founded all the way back in 1847. While the building’s stunning exterior has been immaculately preserved in the years since, the interior has of course been routinely upgraded during that time in order to support the ever-evolving demands of educational environments – including the recent installation of our Type G100 movable wall system.Type G100 is a glazed partition system that provides effective protection again sound transfer when fully closed, achieving up to Rw 54dB. This particular system is comprised of 10 panels, with half being glass and the other half sporting a solid matte black finish – all housed within a sleek black painted aluminium frame.Thanks to the Type G100, the school’s cafeteria layout can changed within minutes, offering the choice between a large open plan space, or a pair of smaller rooms. A fully solid system would not allow for the transfer of natural light to the smaller of the two spaces created when the system is in use, however the glazed panels mean this is not an issue. A pass door also allows for access between the smaller spaces when the panels are being used.

The Palm Tower, a new landmark from master developer Nakheel, under construction at the heart of Dubai's iconic Palm Jumeirah, promises that each of its luxury hotel rooms and apartments will feature one of the best views in the city.To achieve this, the 52-storey, 240-metre-tall hotel and residential building will be clad entirely in glass.Of course, Dubai’s climate means that preventing excessive heat build-up inside heavily glazed buildings will always be a priority. For this project, the architect chose to install 50,000 square metres of Pilkington Suncool™ One 30/21 solar control glass so that residents and guests enjoy both stunning vistas in cool, comfortable surroundings.Silver liningThe glass features a state-of-the-art multi-layer coating that incorporates a microscopically thin layer of silver to help reduce heat transmission to just 21 per cent, while maintaining a neutral colour balance in the light passing through, maximising the views.The building is clad in an area of glass equivalent to 192 tennis courts, but because of the advanced magnetron sputtering technique used to apply the coating, just eight kilogrammes of silver was needed to cover the whole tower. That’s a piece of silver approximately the size of a laptop.Pilkington Suncool™ One 30/21 was originally developed by Pilkington United Kingdom Limited, part of the NSG Group, for Intraco UAE, which has used the glass on a number of projects in the past.Leo Pyrah, product manager at Pilkington UK said: “The view you will get from these hotel rooms and apartments is one of the major draws of this building, but clearly a fully glazed skyscraper in such a hot climate creates challenges from an energy management perspective.“The bespoke coating we have developed alongside Intraco lets the developer and its customers enjoy the best of both worlds – a stunning view with much reduced solar heating.”CentrepieceAs the centrepiece of the world-famous Palm Jumeirah, The Palm Tower is set to become a new landmark for Dubai. When completed, the mixed-use complex will feature 432 apartments and 290 hotel rooms, as well as a rooftop dining and recreation destination featuring a 360-degree roof top infinity pool, a high-end restaurant and a public viewing deck offering sweeping views of The Palm, the Arabian Gulf and the Dubai skyline.As well as creating a comfortable climate for users, the solar-control glazing will also significantly reduce the need for air conditioning, reducing costs and emissions.Leo Pyrah continued: “Dubai is a city that is pushing architectural and technological boundaries and we’re excited to have played a role in shaping the look of its iconic and ever-evolving skyline.”Project: Palm Tower, DubaiClient: NakheelGlazing distributor: Intraco UAE

Crittall Corporate W20 windows are an important component in the refurbishment and upgrade of a prominent industrial site in historic Bath.Newark Works is recognised as a masterclass in the retrofitting of heritage buildings that has transformed a former riverside heavy engineering factory into 21st century workspace.The buildings, dating from 1857 to 1905, are Grade II listed and sit within Bath’s designated World Heritage Site. They were formerly the home of world-renowned crane makers Stothert & Pitt but had fallen into serious disrepair. Their location as part of a larger Bath Quays redevelopment spurred their re-use, underpinned by sensitive treatment, to create 40,000sq.ft of modern workspace.“We specified the Crittall W20 system to replace the existing, single-glazed, cast-iron framed windows that were at the end of their life and deemed beyond repair,” said Nick Brown, Director of Ferguson Mann Architects.He explained: “The Crittall W20 system was chosen due to the need to use a window system that could sympathetically reproduce the fenestration of the large industrial windows – many of which were 3.6m tall – but also provide a huge thermal improvement.”  It was recognised that retaining the original cast iron windows and introducing secondary glazing was neither economically viable nor appropriate aesthetically.“The slim profiles of the Crittall W20 system meant we didn’t have to compromise on the amazing amount of natural light coming into the interior whilst improving the air tightness and reducing the overall heat loss of the building through the windows,” said Brown.He added: “Crittall were also able to recreate the opening vent arrangement of the existing windows, meaning we could also improve the natural ventilation provision to the new workspaces.”Consulting engineers Buro Happold calculated that just replacing the existing single-glazed windows with new double-glazed alternatives with a U-value of 1.8W/m2K would result in a 16 percent annual energy saving. That translated to 21.4 tonnes of CO₂. Over the building’s lifespan of, say, 25 years, that equated to a 535-tonne reduction in CO₂ emissions.In view of the heritage credentials of the buildings, planners and conservation officers at Bath & North East Somerset Council were consulted on the desire to replace the original fenestration with like-for-like steel windows. The local authority was keen that the buildings should be brought back into use after several previous failed attempts. They wanted the site’s historic significance to be respected while avoiding the desire to turn Newark Works into a ‘museum piece’. The installation of Crittall W20 was approved and two of the original cast-iron windows have been retained and refurbished as a reminder of the original building but not in a way so as to compromise the improved thermal performance of the whole.Summing up, Nick Brown comments: “Everyone is really pleased with the final result.”
