Styles of Triple-Glazed Windows We Install and Replace
Triple Glazed Sash Windows
Triple Glazed Sash Windows
Combining the traditional vertical sliding design of classic sash joinery with three-pane sealed units and Low-E glass, triple glazed sash windows provide enhanced thermal and acoustic performance for Georgian, Victorian and Edwardian properties. The additional pane and second insulating cavity improve insulation beyond standard double glazing whilst maintaining the authentic proportions period homes require. We install and replace triple glazed sash windows with Low-E glass, warm-edge spacer bars, multipoint locking systems and uPVC or woodgrain foil frame options.
Learn More →Triple Glazed Flush Windows
Triple Glazed Flush Windows
Sitting level within the frame rather than projecting outward, flush windows recreate the clean profile of traditional timber joinery with a smooth, understated exterior appearance. Triple glazing adds an additional pane and insulating cavity to improve thermal performance whilst maintaining the slim, period-sympathetic profile that makes these windows suitable for conservation areas and modern homes alike. Our in-house installers install and replace triple-glazed flush windows with Low-E glass, warm-edge spacer bars, secure multipoint locking systems and uPVC or woodgrain foil frame options in a range of traditional and contemporary finishes.
Learn More →Purpose-built for period properties where preserving original proportions and detailing is important, triple glazed heritage systems use slimline sealed units engineered to replicate the appearance of traditional single glazing whilst incorporating an additional pane for improved insulation. They suit listed buildings, conservation areas and period homes where improved energy performance is required alongside sympathetic appearance. Bowalker installs and replaces triple-glazed heritage windows with period-appropriate mouldings, lamb's tongue detailing where required and sympathetically matched frame materials, helping support conservation requirements whilst improving thermal comfort and weather resistance.
Learn More →Most closely associated with Victorian terraced houses and Edwardian properties, bay windows add outward projection, increased floor space and a significant boost in natural light to a principal room. Triple glazed bay windows build on that format with three-pane sealed units that improve thermal and acoustic performance beyond standard double glazing. We install and replace triple glazed bay windows with Low-E glass, argon-filled units, warm-edge spacer bars and weather seals, with uPVC, aluminium and timber frame options available.
Learn More →Where a standard rectangular frame would diminish an elevation's architectural interest, arched windows introduce a curved head that adds character to both period and contemporary properties. Triple glazing improves on the thermal performance of standard double-glazed arched units by adding a third pane and second insulating cavity, making them a worthwhile upgrade where heat retention matters alongside aesthetics. We install and replace triple-glazed arched windows with accurately shaped frames, Low-E glazing and thermally efficient sealed units, improving comfort and energy efficiency without compromising the feature they frame.
Learn More →Traditional rural styling, divided-light detailing and period proportions define triple-glazed cottage windows, making them suitable for cottages, farmhouses and character properties where appearance and performance must work together. Georgian bars, astragal detailing and heritage-style mouldings recreate traditional designs, whilst the additional pane and sealed cavity of triple glazing improve insulation beyond standard double glazing. We install triple-glazed cottage windows using engineered timber, woodgrain uPVC and aluminium frames with energy-efficient glazing and durable finishes, preserving each property's character whilst improving everyday comfort.
Learn More →Carefully matched profiles, glazing proportions and traditional detailing distinguish triple glazed historic windows from standard replacements. They are designed for listed buildings, conservation areas and heritage properties where maintaining original character and improving energy performance must be balanced carefully. To achieve that balance, Bowalker installs and replaces triple-glazed historic windows with sympathetic frame designs, slimline units, period mouldings and lamb's tongue detailing where required, helping homeowners improve thermal comfort and weather resistance without compromising architectural integrity.
Learn More →Large fixed glazed areas make triple-glazed picture windows ideal for living rooms, extensions and feature elevations where natural light and uninterrupted views are priorities. Because fixed units contain fewer moving components than opening windows, they can support strong sealing performance when correctly specified and installed. We install and replace triple-glazed picture windows with argon-filled Low-E sealed units, warm-edge spacer bars and secure structural frames, creating bright interiors with excellent insulation, comfort and long-term reliability.
Learn More →Slim sightlines, structured glazing bars and a distinctive industrial appearance define triple-glazed Crittall-style windows, making them popular for contemporary extensions, internal partitions and period renovations. Modern versions commonly use thermally broken aluminium frames to recreate the appearance of traditional steel whilst improving thermal performance. Our in-house installers install triple-glazed Crittall-style windows with secure multipoint hardware, powder-coated frames in anthracite, black or custom RAL colours and carefully aligned glazing bar patterns. Low-E argon-filled sealed units help deliver enhanced insulation performance whilst maintaining the refined steel-look aesthetic.
Learn More →Triple Glazed uPVC Windows
Triple Glazed uPVC Windows
The most widely used residential window material in the UK, uPVC combines low-maintenance performance with strong thermal efficiency across most property types and budgets. Multi-chambered profiles paired with Low-E glass, argon gas fill and the additional pane of triple glazing provide enhanced thermal performance and can help meet current Building Regulations requirements where applicable. We install and replace triple-glazed uPVC windows with energy-rated sealed units, secure multipoint locking systems and a choice of colours and woodgrain foil finishes including anthracite grey, agate grey and Irish oak.
Learn More →Triple Glazed Aluminium Windows
Triple Glazed Aluminium Windows
Strong, slim and designed to span wider openings without bulky framing, aluminium is the preferred frame material for contemporary homes, extensions and commercial conversions where sightline width and design flexibility are priorities. Polyamide thermal breaks interrupt the frame's natural conductivity and, when combined with three-pane sealed units, deliver whole-window U-values that exceed standard double glazed performance and meet current building regulations. Bowalker installs and replaces triple glazed aluminium windows with Low-E argon-filled sealed units, warm-edge spacer bars, secure multipoint hardware and powder-coated finishes across the full RAL colour palette including dual-colour options.
Learn More →For period properties, conservation areas and homes where natural materials are preferred, triple glazed timber windows combine traditional craftsmanship with superior glazing performance. Engineered and laminated timber frames improve stability over traditional solid joinery, whilst the addition of a third pane and second sealed cavity improves insulation beyond what standard double glazed timber units achieve. We install and replace triple glazed timber windows using durable microporous paint or stain finishes, traditional ironmongery and carefully matched profiles, maintaining character whilst improving comfort and longevity.
Learn More →Triple Glazed Fixed Windows
Triple Glazed Fixed Windows
Non-opening by design, fixed windows provide large glazed areas with minimal visual interruption, making them suitable for feature elevations, stairwells and rooms where ventilation is provided by surrounding opening windows. Without opening hardware, fixed triple-glazed units can support strong sealing performance and thermal efficiency across the glazed area. We install and replace triple-glazed fixed windows with argon-filled Low-E sealed units, warm-edge spacer bars and secure structural frames, creating bright interiors with excellent insulation and clean architectural lines.
Learn More →The most common replacement window style in the UK, casement windows combine side-hung or top-hung opening sections with insulated glazing and secure locking systems. Triple-glazed casements add a third pane and a second sealed cavity to the standard format, improving thermal performance without altering the practical everyday operation that makes casements suitable for almost every property type. Our in-house installers install triple glazed casement windows with secure multipoint locking systems, PAS 24-compliant options where required, Low-E argon-filled glazing, compression weather seals and accurately surveyed frames, delivering reliable everyday performance.
Learn More →Tilt and turn windows provide two opening functions within one frame, tilting inward at the top for ventilation or swinging fully open on the vertical axis for safe internal cleaning. Triple glazing improves on standard double-glazed tilt and turn units, making them a worthwhile upgrade for apartments, upper-floor rooms and modern properties where convenience and energy efficiency are priorities. To combine practical operation with superior thermal performance, we install and replace triple-glazed tilt and turn windows with argon-filled sealed units and precision-engineered mechanisms.
Learn More →Recreating the appearance of traditional sash joinery, triple-glazed vertical sliding windows combine classic proportions with improved glazing performance using spring-loaded spiral balance or counterbalanced systems in place of traditional cords and weights. They are particularly suited to Georgian, Victorian and Edwardian properties where period character is important and superior insulation is a priority over standard double glazing. Bowalker installs and replaces triple-glazed vertical sliding windows with smooth balance systems, secure cam locks, Low-E argon-filled glazing and draught-resistant seals, preserving authentic appearance whilst improving comfort and usability.
Learn More →Designed for wide openings, triple glazed bifold windows use multiple folding panels on a bottom rail to create a seamless indoor-outdoor connection no single casement could achieve. Each panel carries a three-pane sealed unit, delivering improved insulation over standard double glazed bifold systems whilst maintaining the flexible, wide-opening operation popular in extensions, garden rooms and open-plan areas. We install triple-glazed bifold windows with aluminium or timber frames, multipoint locking hardware, weather-resistant seals and Low-E argon-filled glazing.

What Our Happy Customers Say
We have had a front door and side panel installed,Team Tim did a great job and were very professional and knowledgeable. Wouldn’t hesitate to recommend the company and this team to any one !
Simon and Brandon fitted our three windows in our garage > studio conversion and were great through the day. Arrived when they said they would, were very polite, respectful and pleasant people. Found answers to questions we didn’t realise about the installation and though we haven’t yet finished the project the windows are a very exciting and big step forward for us. Would recommend this company and this team without hesitation. Thank you!
Had a problem with our door which was installed 3 years ago - Bowalker - Dean - came to site within 24 hours and helped resolved- thank you ! Very pleased with professional and prompt service
Excellent service from a local independent company. Highly recommend.
I had replacement windows installed. Design and advice was good and cost was competitive. Installation was started in a good time to a good standard.
Bowalker have been incredibly helpful and provided me with extremely useful information about the windows and doors at a property I moved into, previously supplied by them. Great customer service, really recommend
Bowalker replaced all of our windows and patio doors in November. They are very efficient and got the job done in the pouring rain but did it quick and professionally. We had a couple of teething issues with the doors after completion and they did not hesitate to come out and rectify the issue. Excellent customer service and a friendly team. Would highly recommend
We had a total of 6 windows fitted at end of June 2025 (2 bathroom(frosted), 1 hallway,1 dining room and two big bay windows complete with 2 window boards). Took 5 days in total as bay windows were load bearing ,the window boards were not in warehouse so took extra time to arrive and fit , the silicone/mastic finish wasn’t great and they cut one end of a window board wrong , but after a telephone call a new team of fitters came out and rectified the mistakes of original fitters that we had noticed , a window pane had got scratched in delivery so they replaced that as well. This was a big job that entailed some mistakes but over time was rectified by bowalker windows by sending out another team of fitters to fix some minor mistakes of original fitters . We went on a recommendation from a work colleague who had used Bowalker windows in the past as were very good. Maybe just improve your fitters mastic silicone skills a bit more but is is an old house of 110 years and nothing is level in this house
