Project: Knightsbridge Gate, 55-91 KnightsbridgeClient: APML EstateMain contractor: Sir Robert McAlpineArchitects: Dixon Jones Architects (lead), Richard Griffiths Architects (conservation including shopfronts design) and MSMR Architects (residential interior design)Installer: Atlantic Contracts (shopfront design and installation), Richard Gent (glazier)In the world of retail, a Knightsbridge address is about as desirable as it gets, which is why so many brands choose to locate their flagship stores on the famed central-London street.For the designers of Knightsbridge Gate, a landmark mixed-use development that occupies an entire block of the street, providing the best possible shopfronts for the retailers that will occupy the scheme’s ground floor was a top priority. So, choosing the right glazing was paramount.While most of the building has been newly constructed, the 120-metre-long Edwardian street-facing façade has been retained, along with its 17 glazed shopfronts. The glazing for each of the frontages is held in place by decorative oak frames that have been carefully re-created according to the original design.Letting window displays shineTo ensure that the units look their best, the designer selected Pilkington OptiView™ Protect OW anti-reflective glass for the street-level glazing.Coatings on the outer faces of the laminated glass reduce its reflectivity to around 2%, compared with around 8% for standard, un-coated glass. The result is that views into the shopfronts are almost entirely un-interrupted by reflections, even on bright days, ensuring that retailers’ window displays are shown off to the best effect.To give further clarity, the glass is Pilkington Optiwhite™ low-iron glass that is almost entirely free from colouration.Rachel Scannell at APML Estate said: “The aim with the retail units at Knightsbridge Gate was to create spaces that the most prestigious brands in the world would be happy to choose in order to display their offerings. The glazing is, of course, a key part of this.“The anti-reflective glass from Pilkington UK is often used by galleries and museums to display priceless artworks and artifacts without compromising on detail, so the retailers that call Knightsbridge Gate home will enjoy the same benefits.”Crafted to lastAdding to the aesthetic appeal of the glazing is the complex shape of the panes that make it up, including a large, curved edge at the top of the central pane in each shopfront. Pilkington UK engineers worked closely with the carpenters to precision cut each pane of glass to ensure a perfect fit.The shop front windows are as tough as they are beautiful as they consist of two panes of glass laminated together with a strong polyvinyl butyral (PVB) interlayer. This ensures the glazing can stand up to all the forces that may be thrown at it, from wind-loading to any attempts to smash the glass.Due to the anti-reflective coating being applied at a high temperature when the glass was being made, it is highly scratch-resistant, ensuring its clean and clear appearance will last for many years to come.Peter Maj, business development manager at Pilkington United Kingdom Limited, part of the NSG Group, said: “By selecting Pilkington OptiView™ for this project, the designers have demonstrated that it is the product of choice for retail applications where the glazing will be under the utmost scrutiny and needs to look its best.”Along with the shop-fronts, Pilkington UK also supplied 300 m² of Pilkington Optiphon™ OW acoustic glass, which has been used throughout the offices and apartments on the upper five floors of the building to provide noise-reducing secondary glazing.

Project: Solina observation tower and gondola stationClient: PKL and PFR GroupsThe Prime Minister of Poland, Mateusz Morawiecki, hailed the opening of a new observation tower and gondola lift in the Bieszczady Mountains as an investment that will strengthen the magnetism of Solina, a major tourist hotspot.At the opening, Morawiecki remarked how Solina is a beautiful place where nature is untouched by the human hand*. The picturesque holiday destination in South East Poland is famous for its forest-covered peaks and vast open water, home to the largest artificial lake in the country.These surroundings make Solina equally as popular with birds as it is for tourists. The area is home to 130 species of birds, including eagles, hawks, sparrowhawks, smews, black terns and songbirds; while also being located on a main migratory route.Protecting Solina’s bird population was therefore a top priority for the two groups behind the tourist attraction, the PKL Group (Polish Cableways), which provide sustainable mountain tourism services, and the PFR Group (The Polish Development Fund), a state-owned financial group which invests in sustainable social development, who paid close attention to the needs of bird species throughout the design and construction phases.They turned to specialist glass for the gondola station and the observation tower to help protect its feathered neighbours.Glass designed to protect birdsPilkington AviSafe™, an innovative glass designed to protect birds, was specified for the project’s glazing. Its unique patterned UV enhanced coating disrupts the reflection on the glass, helping birds to see a clear barrier.Jason Eggerton, UK specifications manager at Pilkington United Kingdom Limited, part of the NSG Group, explained: “Experts distinguish three effects leading to birds colliding with glass.“The mirror effect is where birds mistake the glass’ reflection as reality. Corners of buildings or narrow passageways can also lead to collisions as they allow birds to see the habitat on the other side of the building. Thirdly, the fly-through effect is where birds may also not see the transparent barrier and aim to fly into a building to a perching spot, such as within an atrium.“The gondola station and observation tower are surrounded by forests making bird collisions due to reflections of the trees a particular risk. Ultimately Pilkington AviSafe™ disrupts these reflections making the glass more visible”The coating is designed on the principle that birds see in a different light range to people, making Pilkington AviSafe™ glass more visible to birds while remaining aesthetically appealing on the exterior surface. From the inside however, it’s barely visible to the human eye.It was used in the large, modern glass facades of the gondola station in combination with Pilkington Suncool™ 70/35 and Pilkington Optilam™ glass, which ensures effective thermal insulation, solar control and safety.The Pilkington AviSafe™ glass was manufactured at the Merseyside manufacturing site of Pilkington United Kingdom Limited, part of the NSG Group, in St Helens.Jason Eggerton continued: “Making buildings truly sustainable goes beyond emissions and energy efficiency. Architects and specifiers increasingly need to consider how their projects impact local wildlife too.“Pilkington AviSafe™ has clear value amidst nature reserves, forests and mountains in Solina. But many of the world’s major cities are located on bird migratory paths, where tall, glazed buildings can increase the chance of collisions.“We’re proud to support a project of such high prestige and economic significance in Poland, and to play our part helping Solina’s tourism industry to maintain its minimal impact on nature and local wildlife.”

Project: 1 Aylesbury Street, Clerkenwell, London, EC1R 0DRClient: MeritcapeArchitect: Atum Design LabM&E consultant: EngDesignProtecting Cities Against Fire with Advanced GlazingDaylight-flooded spaces command a premium from tenants, but in the densest urban areas – where buildings are very tightly packed – it can be difficult to achieve. Not least because of the need to protect against the spread of fire.This was the challenge for developer Meritcape when they set out to refurbish 1 Aylesbury Street – a converted historic warehouse building in Clerkenwell, East London.The designers wanted to fill every floor of the building with natural light, from both the front and the back of the building by using floor-to-ceiling glazing on every floor. However, the rear of the property was just three metres away from a neighbouring building.To prevent fire spreading from one building to the next, building regulations specify the fire resistance that external walls need to be able to provide. This is given as minimum requirements for integrity – how long they can contain smoke and flames – and insulation, or how long they can prevent the escape of heat. Steve Bond, technical and customer support manager, fire, at Pilkington United Kingdom Limited, said: “When you have two buildings this close together, standard glazing is not an option, as it doesn’t put up enough of a barrier to fire spreading outwards from the building.“That’s where fire-resistant glazing can make a big difference. By providing protection against fire while also letting light flow in, we can create light-filled spaces in very built-up parts of the city where not long ago it wouldn’t have been possible.“As well as sealing in flames and smoke for at least an hour, the glass also provides radiation shielding that reduces the amount of heat energy that can pass outwards through the glass – another key means of spreading fire.” The rear façade of the building is glazed in Pilkington Pyroclear® Plus insulating double-glazed units, delivering not only the right level of fire resistance, but have also been designed to give excellent thermal insulation (U-value) properties to reduce heat-loss from the building.Davood Kiani, Senior Project Consultant at Meritcape said: “Those looking for modern commercial space expect floorplans to be well lit with natural light, and this is one of the main design challenges when working with buildings in the most densely urban areas of the city.“Fire regulations are one of the big reasons for this, so Pilkington fire-resistant glazing means we can achieve the best of both worlds - a building that meets or exceeds all of the safety regulations while also feeling spacious and airy.”A total of 800 m2 of Pilkington glass was used in the project, including in the front façade of the building, in which hundreds custom-sized small double-glazed solar-control units were used to imitate the crittall steel-framed windows that are a signature feature of buildings in the area.Images by S G Photography

Set in beautiful grounds this former coach house is nestled in a picturesque Cotswold village.This stunning orangery was the perfect solution for the family who wanted to have a light filled room, from where they could sit and enjoy their garden throughout the year.The stone-coloured exterior paint finish of the David Salisbury orangery is the perfect complement to the sandy-coloured Cotswold stone and stone roof of the main building.The glass lantern benefits from Pilkington Activ™ Blue self-cleaning glass, which has both self-cleaning and solar-control properties plus high performing thermally insulating Pilkington K Glass™ S as the inner pane of glass.The result of this carefully designed addition to a home that already oozes character and charm is a light filled environment that can be use throughout the Summer and Winter months, where the family can sit in total comfort.Images courtesy of David Salisbury.

County Sligo has been blessed with a brand-new luxury hotel, the internationally renowned Radisson SAS Hotel, where the comfort of guests and staff is of paramount importance. Every precaution has also been taken to ensure the safety of residents including the installation of high quality, clear view fire-resistant glass products, Pilkington Pyrostop® and Pilkington Pyrodur®, which have been fitted extensively throughout the entire hotel.Pilkington Pyrodur® is a laminated glass with a special interlayer, developed for the optimum combination of minimum thickness, integrity fire resistance and impact performance. In a fire, the glass forms an opaque barrier to exclude flames and hot gases as well as blocking the sight of the fire, hence reducing panic. In addition to its integrity performance Pilkington Pyrodur® reduces the transfer of radiant heat significantly.Jackie Corcorran of main contractor, J J Rhatigan & Co. Galway was closely involved in the specification of the specialised glass alongside White Bros. Joinery Sligo & Jim Walsh of Greaney Glass Galway. 160 m2 of 10 mm Pilkington Pyrodur® with a 30-minute integrity rating was installed within the corridors of the building. In other areas where there is a slightly greater risk of fire, such as the kitchen area, internal doors and function room screens, were fitted with 21 mm Pilkington Pyrostop®, which provides 60 minutes fire integrity and insulation.Specialist glass & glazing contractors, Greaney Glass, were responsible for installing the fire-resistant glass and Ivan Greaney, Managing Director, comments: “For such a prestigious project it was imperative we used a fire-resistant glass we could trust. There could be hundreds of people within the hotel at any one time so we needed to use materials that would provide maximum protection under the most extreme circumstances. As Pilkington Pyrostop® and Pilkington Pyrodur® are backed by a full suite of impact and fire performance tests, we had no doubts that this was the ideal glass for this project.”Pilkington Pyrostop® and Pilkington Pyrodur® provide excellent levels of protection and have been tested and assessed to BS and EN standards. Not only do they offer excellent fire-resistance they also fully comply with impact safety tests and permit safe breakage in the manner of a laminated glass. In addition, they provide acoustic improvement over standard fire-resistant glass, an important consideration in the hotel that offers a peaceful and relaxing retreat for guests.

Project: Slimming World headquartersClient: Slimming WorldMain contractor: Morgan Sindall ConstructionArchitect: CPMGWith its newly extended headquarters in Alfreton, Derbyshire, weight-loss organisation Slimming World wanted to create a landmark building for the brand that would both provide an ideal working and training space for its people and deliver excellent environmental performance.Glazing plays a key role in the £8.5 million scheme, both aesthetically and in terms of its use of energy.At the heart of the building is a large atrium with a full-height glass front elevation and a glazed roof running right to the back of the space. Meanwhile, one of the wings connected by the lobby area features large ‘picture windows’ that deliver views over the facility’s attractive, leafy grounds.High-performance envelopeBecause much of the building’s envelope is glazed, the designers faced the challenge of avoiding the need for an energy-intensive climate-control system to create a comfortable environment for users all-year-round.Lee Shaw, Business Development Manager at Pilkington United Kingdom, explained: “The twin challenges any building with extensive glazing faces are loss of heat on cold days and excessive heating as result of direct sunlight when the weather is warmer.“The combination of products we have supplied to this project use advanced coatings cleverly to minimise these two effects, helping to smooth out the peaks and troughs that can lead to uncomfortable temperatures, expensive heating and air-conditioning bills and wasted energy.”The curtain walling system uses double-glazed units manufactured by Pilkington, incorporating Pilkington Suncool™ 60/31 T solar-control glass and Pilkington Optitherm™ S1 Plus, a low-emissivity product.The solar-control glass features a state-of-the-art coating that transmits only 31 per cent of the sun’s energy, while still allowing for 60 per cent light transmittance, so that occupants still get a clear view outward.The low-emissivity glass meanwhile features a coating that reduces outward radiation of heat, so that less is allowed to leave the building on colder days.Uninterrupted viewsThe same glass is used in the atrium wall and roof but is held in place using the latest structurally glazed units from Schueco. These deliver glazed surfaces with ultra-low-profile frames to minimise interruption of views from the building, as well as daylight flowing into it.Extra strength is added to the atrium glazing by including a layer of laminated glass on the inner pane, to help the large units stand up to forces exerted on them by the wind and potentially the weight of snow during the winter.Lee Shaw continued: “This project demonstrates the range of glazing solutions we are able to offer, with a combination of curtain walling, structural glazing and roof glass, all of which has been manufactured in the UK.“The architect has used timber slats to deliver some degree of solar shading, but the extensive area of glazing enclosing the space means there would still be significant risk of excessive heat build-up. The glazing specified minimises this effect, saving energy and money while also delivering a more comfortable and stable year-round climate for those using the building.“This is also one of the first projects to feature Pilkington Suncool™ 60/31 Pro T glass, which is now fully manufactured in the UK, following recent re-location of production from Germany. It’s great that we’ve been able to combine a made-in-Britain success story with a new chapter for a well-loved British business.”The completion of the building is the latest chapter in the story of Slimming World, which started when founder Margaret Miles-Bramwell OBE, then 21 years old, first began holding Slimming World groups in Alfreton in 1969. Now, 50 years later, there are 19,000 local groups across the UK and Ireland, run by a network of more than 5,500 self-employed Consultants.The new headquarters includes extensive training facilities, meeting and office spaces, as well as a brand new 550-seater restaurant for staff, guests and Consultants visiting for training.Paul James, Slimming World’s Facilities Manager, says: “People have always been at the heart of Slimming World’s success and so ensuring that our people – our head office staff and Consultants – have the facilities and environment they need to do the best job possible has been a real priority for us. The new building will ensure we have the facilities we need to train and support all of our fantastic Consultants who deliver exceptional service to our members to support them to lose weight and live healthier, happier lives.“Having large expanses of glass has provided us with a beautiful, light-filled space that will be comfortable and inviting for everyone who uses the building right through the year.”

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

The Emerald rises 40 stories above one of Seattle's most desirable neighbourhoods. The LEED Silver certified building manages to redefine luxury living. According to the idea of Hewitt architecture studio from Seattle, high-quality, natural materials as well as the sophisticated daylight concept blur the boundaries between the interior rooms and the picturesque nature. This is particularly evident on the second and third floors where the Pilkington Profilit™ channel glass system spans the outside of the fitness centre and community meeting spaces. Large, glazed areas can diffuse extensive amounts of natural light deep into interior spaces without loss of privacy.Apart from channel glass, Pilkington Pyrostop® Line fire protection glass also ensures natural light deep into the interior. Both products were installed in systems from Technical Glass Products.A transparent façade with Pilkington fire-resistant glass was planned to separate the fitness studio from the corridor in terms of fire protection. The spacious inner façade made of glass provides plenty of light in the training area and enables the desired feel-good atmosphere in the fitness studio. At the same time, it directs a lot of light into the interior of the building.The fire-resistant glass Pilkington Pyrostop® Line was used in a Fireframe Clearview® system from TGP with Heat Barrier frames and doors from the Fireframe Heat Barrier series. This generously fire-resistant and at the same time impact-resistant solution could be implemented without a vertical frame between the individual panes, with almost colourless transitions between the adjacent glass panes and without coloured inner glass spacers.

The newly completed 122 Waterloo Street development in the centre of Glasgow offers its occupants floor-to-ceiling glazing throughout, with almost uninterrupted views thanks to the latest Schüco curtain-walling system designed, manufactured and installed by Edinburgh-based façade specialist Charles Henshaw & Sons Ltd.But, impressively, the landmark building – which will be the Glasgow headquarters of global financial services firm Morgan Stanley – will also be one of the most energy efficient buildings in Scotland, thanks in part to high-performance glass coatings from Pilkington United Kingdom Limited.The scheme has been certified BREEAM Excellent, and achieved an ‘A’ rated Energy Performance Certificate (EPC), the latter based on a detailed assessment of the building’s energy performance. The glazing helps to minimise this by reducing energy emitted from the building, as well as the heating effect of the sun, both of which can make maintaining a comfortable interior climate more energy-intensive.A glass for all seasonsThe scale of the building and the large area of glass used means that excessive radiation of heat from the building could lead to rapid heat loss during colder conditions, requiring an increase in heating to keep the interior warm.To mitigate this effect, the glazing features a Pilkington Optitherm ™ S1 Plus low-emissivity coating which reflects radiated heat back into the building.The second issue that can affect buildings where most of the envelope is glazed is excessive heat build-up when the sun is shining directly into the interior. This can present a challenge for building managers, often requiring high levels of energy-intensive air conditioning.To combat this, a solar-control coating has been used, reducing the amount of heat energy that is able to enter the building while maintaining high levels of transparency. Michael Metcalfe, commercial sales manager at Pilkington UK, said: “The Pilkington Suncool™ 70/35 T coating selected by the design team offers high visible light transmittance, reduced solar transmittance and excellent low-emissivity all in one product.“This means the floor space will be brightly lit by sunlight but won’t suffer from overheating on warmer days.”Clear viewsThe coatings are not the only innovative part of the glazing used in the project, as the glass is held in place by the latest structurally bonded curtain wall system from manufacturer Schüco. Each unit contains a large pane of clear glass and a smaller pane of opaque, coloured spandrel glass, creating horizontal lines across the façade between each floor of the building.Michael Metcalfe continued: “The metal carrier frames in which the glass sits are extremely low profile, so the edges of the panes of glass are very close to one another. This removes the mullions normally associated with unit-based glazing systems, creating a flush glass surface with almost uninterrupted views.”The clarity of the glazing was further improved by the use of Pilkington Optiwhite™ true low-iron glazing throughout, which significantly reduces the slight green tint that is inherent in standard float glass.On the ground floor, Pilkington Optilam™ laminated glazing was used to provide protection against manual attack and increase the security of the building.Completed in December 2017, the nine-storey building also includes 155,000 sq ft of Grade A office space.Project: 122 Waterloo Street, GlasgowClient: HFD GroupArchitect: Micahel Laird ArchitectsCurtain walling supplier: SchücoInstaller: Charles Henshaw & Sons LtdImages courtesy of S G Photography
