"windows"

Based in Lincoln this multiple dwelling new build project required sash windows to fit its architecture. The homes were built using local stone which meant standard white windows wouldn’t match its high-end appearance. The developers also needed windows that came with high performing benefits such as thermal efficiency, security, all while remaining maintenance-free. Using our in-house spray shop, Charisma Rose was specified in a solid cream option that complimented the stonework beautifully. The trickle vents were also colour matched to seamlessly blend in with the windows and keep the luxury charm of the buildings. A traditional astragal bar grid was picked to match Georgian architecture as well as run through horns and a 2/3 unequal split for the ground floor. This project ran smoothly providing more than 50 sash windows over seven dwellings. All windows were manufactured and delivered on time and snag-free, meaning there was no impact on the developers schedules.

Chipping Homes specialises in building high quality, architecturally sensitive homes, which made the choice of contractors critical. This was especially the case for the window contractor – with over 300 windows required, getting the right look and feel for this element of the project was essential. The windows specified for the contract were Optima from Profile 22, the UK’s leading award-winning commercial window system. The fabrication and installation contract was awarded to Profile 22 Approved Contractor Kingfisher Windows, a leading manufacturer and supplier of windows, doors and conservatories.

This Edwardian home was transformed inside and out in 2021. Part of the renovation included changing the original single glazed, draughty timber sash windows. The sashes were previously painted shut to minimise heat loss, but this was proving both inconvenient and ineffective. The homeowners wanted to find replacement windows that were indistinguishable from their original timbers but in a low maintenance form that offered significantly better security and thermal efficiency. Having spent months looking around for the right solution, the homeowners found Roseview and, specifically, Ultimate Rose. Being the most authentic window on the timber-alternative market, they would match their original timber sashes like for like but with this maintenance free alternative. The windows were finished in a chalk white texture with an Edwardian astragal bar design, seamless run-through horns, deep cills, Secure by Design accreditation and shark fin limit stops throughout. Additionally, Ultimate Rose comes with ‘A’ rated energy efficiency as standard. For the homeowners, this means lower heating bills month-to-month and a reduced carbon footprint. This is due to Roseview sash windows being double-glazed and fully weather-sealed, unlike the home’s original timber windows. As a result, the homeowners now have sash windows that never need repainting and will naturally keep their home insulated and secure without sacrificing authenticity.

Dallochy House owners Mark and Jenny Sykes had always dreamed of building their own home. And after house-hunting for a number of years in Aberdeenshire, realised they would have to make their dream come true to get a property that ticked all their boxes! They were searching for a new home which would be warm and easy to heat, in their local village and in the catchment area for a good school.  Paul McWilliams from Annie Kenyon Architects, orientated the house to optimise south facing solar gain, with expanses of glazing from Rationel to make the most of the views, and stilts to accommodate the sloping topography. The couple incorporated stone from the former cottage on the site, into the gable-end of the new build.  “It has been a very happy and stress-free journey,” say Jenny who chose James Hall Joinery as main contractors. “I cannot rate the professionalism of Paul and James highly enough. We expected stress, hiccups, problems but James project managed everything so smoothly that he took the stress out of the whole process.”  “We chose Rationel windows for a number of reasons. James Hall recommended them to us having used them on several other builds. He was able to provide photos of windows, doors and testimonials. Their distributors ADW have a showroom, at Sauchen, which was very convenient for us to visit and it was particularly helpful to see so many products on display. We were impressed with the quality, the choice available and could tell that the investment was absolutely worth it. The colour choices were to our liking, as was the option to have alu-clad external finish onto the natural timber frames.  We think the windows just look really good with the cladding and stone work and of course allow you to appreciate the views.” 

On this office refurbishment the original windows were non-thermally broken aluminium and for that reason not suitable for a residential tenancy.With the windows being on the 12th floor it would have been extremely difficult and expensive to replace them - due to scaffolding etc. Therefore, after a recommendation, the client decided to source Incarnation secondary glazing.As an office refurbishment in a busy built-up area, noise reduction was a key consideration. Using a hidden coupling bar between two units was a key feature, allowing the secondary glazing to match the sightlines of the original windows perfectly. By installing the secondary glazing with an air gap of 150mm between it and the existing window resulted in an impressive decibel reduction.

With 37 high-rise buildings within its remit, Solihull Community Housing (SCH) is responsible for the upkeep of more than 1% of the UK’s entire high-rise stock. Part of a stock of 11,000 properties that SCH manages and maintains on behalf of Solihull Council. A window replacement programme on this scale – and on high-rise buildings especially – would normally represent an astronomical undertaking, incurring huge installation costs. However, SCH and its supplier and contractor partners have worked together to devise an innovative solution that allows all new windows to be installed from the inside.

It was a pleasure for all involved to work on this outstanding project, an original Arts and Crafts home which has been impeccably refurbished.The recent works included extending the house, as well as opening up and changing the layout. The interior has been modernised with a contemporary touch, but cleverly retains and enhances the home’s character. The interior design of the whole home is stunning. The bedrooms and bathrooms have been individually designed and are unique to their user. Mural wallpapers, vibrant pops of colour and striking, high quality fixtures and fittings help achieve this.A combination of leaded EB20 steel windows and W40 steel doors with genuine T bars were chosen to replace the external fenestration. The new windows and doors have slim, elegant frames but bring the benefit of improved thermal efficiency and security. Internally, a bespoke W20 door screen has been used to divide the kitchen and dining area.Both the client and architect are delighted with the outcome. Steven Harp from Harp and Harp said: “This project involved a delicate balance of modernising a home that had been barely touched in a century for 21st Century family life whilst trying to retain the beautiful Arts and Crafts character and charm of the original house. The new doors and windows by Clement were a perfect product to fulfil this brief, providing modern standards or thermal comfort with an aesthetic and quality that blended seamlessly with the elegance of the original metal windows that were still on the house.”The client said: “I was initially unsure about changing the fenestration and doors in our property, as they are such an important part of the building’s character, history and aesthetics. However, from our first meeting with Clement Windows, who were recommended by our building surveyor, I knew I needn’t have worried. They talked us through the different options in detail, provided extensive designs (and were always prepared to amend and refine these subject to our thoughts!) and also worked seamlessly with our architects to ensure that all we asked for was delivered and more. The finished product far exceeds any expectations that we had for windows and doors that matched our original steel windows and doors, now giving us the perfect look for the house with the added bonus of double glazing and additional safety and security. Their communication throughout has been excellent and we have felt looked after every step of the way. Installation was done ahead of schedule and the only issue we’ve had post installation has been dealt with efficiently and they have always had someone available to pick up the phone to us and come to site when needed. Really cannot recommend this wonderful company enough, for both their products and the overall experience. Thank you!”

The owner of this charming period cottage needed to replace original timber sash windows that had deteriorated, and which were cold, drafty and lacking in security.

This grand Edwardian property began life as commercial premises, but has recently been given a new lease of life by urban regeneration experts Stockwool Design. The site near the City of London, known as Sterling Mansions, has been transformed into 59 quality apartments for Berkeley Homes. We designed, manufactured and installed 216 traditional timber flush casement windows with feature moldings. Fitted with high acoustic double glazing on the Leman Street elevation, the windows achieved an impressive 45 dB Rw acoustic performance rating (55.4 ACf / 12 / 44.1 Low-E glass).

This Grade II listed building in Thames Ditton dates from 1792. The former manor house, priory and chapel was repurposed as a care home in 1905 by the Nuns of Compassion, yet in recent years the historic buildings have posed challenges to delivering modern standards of care. Oliver & Robb Architects have rationalised the design in a renovation project to created 78 luxury bed spaces. We were appointed to design, supply and install a total of 263 timber tilt and slide sash windows, tilt and turn windows, single doors and French doors to sympathetically upgrade the property.

University Arms Hotel, the oldest hotel in Cambridge, dates from the 1840s when it first opened as a coaching inn. Extensions followed in the 1930s an 1960s; but in 2013 John Simpson Architects began returning cohesion and grandeur to the building. The aim was 190 bedrooms boasting 5-star luxury. We were proud to be awarded the 14-month contract to design, supply and install 300 timber box sash windows, 50 balcony French doors, and 28 curved-on-plan sash windows. We also produced large bespoke entrance screens, and undertook the restoration of leaded light glass.

The distinctive, copper-clad four-storey building is a thoughtful solution to higher-density living, underpinned by sustainable building performance. Generous glazing is a key feature of the project, with VELFAC triple glazed slim-framed composite windows bringing extra light into apartments and communal spaces.

A great example of 1930s Art Deco architecture, The Douglas Building sits on Great Titchfield Street in London’s West End. Formerly known as The Media Village, Douglas House was acquired by serviced office providers The Office Group (TOG) from landlords The Langham Estate in 2019. TOG together with Note Design Studio transformed the building with a colourful concept that blends the distinctive 1930s features and gives a sense of fluidity, openness and light throughout.As its former name suggests this area of London is a hub for local media and IT businesses operating out of the West End and the brief for the building was to create a flexible workspace where people can feel stimulated by their environment leading to greater productivity. Wellness was also a central focus and the building includes an oxygen room, a parents’ room and a roof terrace which are all integral to enabling and inspiring everyone who enters.Well ventilated and an abundance of natural light have become buzzwords in the COVID era and the more than 300 new steel windows from the Clement EB24 range which were chosen by office fit out and refurbishment contractors Parkeray perfectly facilitate both. Polyester powder coated in Pure White and furnished with Warren handles in a satin chrome finish the windows lend the building a contemporary look on the outside as well as supporting the 21st century ways of working inside.Peter Clement, Chief Executive of Clement Windows Group, commented:“As with all prestigious window replacement projects of this magnitude Clement took part in a competitive tender process. Whilst this was in play we understand that both Parkeray and the client’s team had the opportunity to compare our EB24 steel window to others being considered. We believe it was the quality and overall finish of EB24 combined with an attractive price and fine references that convinced them and the client to proceed with us.”

The town of Whitchurch in Hampshire is a special place: most of the town is a Conservation Area, the amount of wildlife in and near the River Test means its course and banks are designated as a Site of Special Scientific Interest, and the town is the Gateway to the North Wessex Downs Area of Outstanding Natural Beauty, the third largest of Britain's 46 AONBs. The current Town Hall was built by a local landowner, Lord Middleton, in or around 1791, using some of the timbers from the Old Town House that had stood in the centre of The Square, and was demolished in the 1780s. During the 1800s the building had many tenants including the Mechanics Institute and a furniture warehouse.Records show that in the 1900s the building was also put to a variety of uses. The local Magistrate held sessions, two rooms were used to shelter Military Units passing through Whitchurch, and in 1919 the building was used by the National Federation of Discharged Soldiers and Sailors. Parish Councils were set up in 1896, but met at the Poor Law Institute (the Gables). More recently, the National Fire Service was accommodated in the lower middle section of the building. In 1946, Midland Bank, (now HSBC) was in the lower right hand corner. The Town Band practiced here, and the British Legion used the upper floor. Recently, an extensive program of refurbishment works has taken place to improve the Grade II* Listed Building. This included new steel doors and windows by Clement for the front elevation. The Clement W20 range was chosen for both, with krypton gas filled units. Ash pull handles perfectly complement the steel doors and Boleyn handles were chosen for the steel windows. Sarah Weir, Clerk at Whitchurch Town Council said ““The Town Council are really pleased with the new windows and door which are modern, practical and in keeping with the historic building”. 

The conversion of a west London former town hall to include residential accommodation features Crittall windows, carefully designed to preserve the building’s original character. The former Acton Town Hall, in Ealing London Borough, has been partly converted to provide a public library and leisure facilities but the Grade II listed structure also now contains a range of apartments. The building, which dates from 1909, was designed in an Italianate palazzo style, executed in locally made red bricks with Portland-stone dressings.  For the refurbishment and conversion the windows within the original building were replaced with Crittall Corporate W20 profiles.

Rose Collection sash windows are often used in traditional heritage properties, but – as this stylish post-war Surrey home shows – they work just as well in more modern buildings.

Traditional Windows and Doors for a Historic Pub Renovation and Executive Housing DevelopmentThe Melbourne Arms, a cherished historic pub near Derby, underwent a remarkable transformation into a prestigious executive housing development. To preserve the charm and character of the old English pub, bespoke traditional windows and doors were essential.Restoring the Melbourne ArmsThe Melbourne Arms, a listed building with a rich 228-year history, had fallen into disrepair until Stanton Developments acquired it in 2018. They embarked on a comprehensive restoration of the pub and the creation of five additional houses on the site. Unsuitable extensions were removed, allowing the pub to be transformed into two linked detached four-bedroom family homes. The restoration honoured the original features, including the iconic stacked chimneys and distinctive inglenook fireplace."From the double-height skirting to the reinstated upstairs fireplace, we feel privileged and proud to have renovated this historically significant building," expressed Andy Turner, Stanton Developments.Creating an Enclave of HousesIn addition to the pub restoration, Stanton Developments built five new properties on the site, forming an enclave that harmoniously complemented the landmark pub. Each house was individually designed while respecting the aesthetics of the original structure and blending seamlessly within the local conservation area. The houses were named after former proprietors and notable figures associated with the property's history.Award-winning architect Matthew Montague designed the properties, adding his touch of excellence to Stanton Developments' vision.Gowercroft's ContributionGowercroft, known for their expertise in traditional windows and doors, was selected to provide the windows and doors for the Armsgate Development. The focus was on combining historic styling with modern performance, using the finest materials. Accoya® Windows from the Hardwick Range, featuring flush casement windows, and a selection of Accoya® doors from the Melbourne Range were chosen.To maintain individuality, each house had subtly different front door designs and colours, tailored to the specific property. Elaborate ironmongery and Accoya surrounds distinguished the larger properties, setting them apart.Attention to DetailPreserving the authenticity of the original window design was crucial for the plot that once housed the pub. Gowercroft crafted traditional Georgian bar windows, while also introducing unique triangular-shaped windows that added a touch of originality to the development.The combination of Stanton Developments' commitment to historic restoration and Gowercroft's expertise in traditional windows and doors resulted in a remarkable housing development that seamlessly merged the past with the present.

After many years of being out of use, the former police HQ (CID) building on Bridewell Island in Central Bristol has been renovated and is now the new YMCA Bristol hostel. John Perkins Construction carried out the work along with Ferguson Mann Architects and assistance from the Bristol City Council Conservation Team. Preserving the beauty of this Grade II Listed Building, which dates back to 1928, was paramount although it was vital that the completed building offered a modern specification for 21st century living. Clement Windows Group were selected to provide the new steel windows.

78 St James Street, a very special office refurbishment in the heart of London’s Mayfair, has involved a slew of skilled and experienced contractors to make the Grade II* Victorian building a commercial space fit for 21st century working while retaining the building’s magnificent fabric. Halifax Glass has used Hodgson Sealants’ U9 silicone for sealing the building’s impressive timber window units.  The windows, which are the full height of the storeys on the front façade, required a specialist glazing company to meet the demands of the project. Halifax Glass has many years’ experience in creating architectural glazing solutions and was called in to produce and install the windows at St James Street using Hodgson Silfix U9 Silicone Sealant for the job.  Halifax Glass also used quantities of Hodgson’s Flexistrip, the market-leading load-bearing security glazing strip for installing double glazed units, laminated glass and single glass into windows and doors.

In the heart of Bristol’s City Centre lies The Pithay, now known as Programme. This immense building, originally built in the 1960s was tired and required refurbishment. After being acquired by Resolution Property in 2016 a plan was developed by Buckley Gray Yeoman, based on Resolution’s ambitious brief to revitalise the building. Clement Windows Group was chosen as the preferred company to manufacture and install the 510 new steel windows required. Clement were thrilled to win the job, particularly as the current Chief Executive Peter Clement’s father had installed the original windows back in 1966!

Arden windows were approached by a Main Contractor that was looking for a manufacturer and installer of high quality sliding sash windows to replace several hundred windows across various properties in on behalf of the Borough. The client’s key considerations were to ensure that their residents were provided with a thermally efficient high-performance window that would provide a better home whilst ensuring planning authorities and local conservation were content with the design and aesthetics of the replacement windows. Arden were invited to be involved with the project at a very early stage and were able to offer assistance with the submission of the planning applications, including discussions with conservation officers for the area. Ultimately Arden surveyed the properties, produced drawings to demonstrate existing and proposed details for the replacement windows and achieved full planning consent. During the process, Arden representatives worked directly with the Conservation officers including providing sample windows and attending a number of meetings in an effort to ensure that the replacement double glazed windows were acceptable to all parties. One of the key issues encountered was the initial reluctance of the Conservation Officer to allow the single glazed windows to be replaced by double glazed units using a bonded spacer bar as opposed to a more traditional solid glazing bar. As the client was keen to ensure costs were kept to a minimum and thermal performance was improved, the preferable choice was to use Arden Window sliding sash window with a bonded bar and a “plant on” timber glazing bar. Once Arden had manufactured a full-size sample window this was shown to the Conservation officer and the benefits explained. Due to the traditional appearance of the Arden window, the planning applications were approved and the project was able to proceed. Early engagement with Arden was key to the successful outcome of the project. This ensured that the design and planning requirements of the client and conservation teams were realised. It also facilitated the planning of manufacture and installation, coordinating with the main contractor at a very early stage thus ensuring the project was delivered and completed on time and within agreed budgets.

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.

An urban luxury conversion in the heart of Nottingham City Centre. This project involved the contractor converting a commercial building within a conservation area into luxury apartments.There were various design issues that needed to be overcome, including curved on plan bays. The curved bays required a bay pole system to allow the installer to gain the necessary shape profile.An added challenge was window size. There were a number of large, multi-part windows in apartments accessed via tight staircases and small door openings. To overcome this we made some of the larger units in kit form and sent one of our experienced fabricators to site to assemble them in situ.A key requirement was noise abatement which was achieved with acoustic glazing and an optimal 100mm air gap, adding - on average - 35DB of noise reduction on top of that provided by the primary windows.The end result were minimal profiles matching original sightlines, coupled with significant thermal and acoustic performance improvements.
