Types Of Windows We Install
Aluminium Sash Windows
Aluminium Sash Windows
Vertical sliding operation, authentic sash detailing and durable aluminium frames make aluminium sash windows a practical choice for period-inspired renovations, contemporary homes and properties where traditional styling and modern performance need to work together. Modern spring balance systems replace traditional weight-and-cord mechanisms, providing smoother and quieter operation with reduced maintenance. We install and replace aluminium sash windows with thermally broken frames, Low-E double glazing, secure multipoint locking systems and accurately proportioned sash profiles, preserving traditional character whilst improving insulation, durability and everyday operation.

Aluminium Flush Windows
Clean architectural lines and a level exterior profile where the sash sits neatly within the frame define aluminium flush windows, making them well suited to modern homes, extensions and renovated properties where slim sightlines and a refined finish are important. The flush face removes the stepped appearance associated with standard window designs. Our in-house installers install and replace these windows with thermally broken aluminium frames, high-performance Low-E glazing, durable RAL powder-coated finishes and secure hardware, delivering visual appeal, energy efficiency and long-term reliability.
Learn More →Contemporary homes, extensions and properties with larger glazed elevations benefit from aluminium bay windows, where the traditional bay form combines with the strength and slim sightlines of aluminium to increase natural light, create additional interior space and support expansive glazing. Bowalker installs and replaces these windows with thermally broken aluminium frames, Low-E glazing, argon-filled sealed units, warm-edge spacer bars, secure multipoint locking systems and durable powder-coated finishes, with RAL colours and dual-colour options available to complement different architectural styles. The result is a bright, comfortable bay structure with long-term thermal performance, security and durability.
Learn More →Precision-manufactured curved frames and thermally broken aluminium profiles give aluminium arched windows a distinctive architectural presence suited to feature elevations, extensions and properties where unique shapes introduce visual interest. Each frame is formed to maintain accurate proportions and consistent sightlines across the curve. We install and replace aluminium arched windows with high-performance glazing, secure hardware and weather-resistant finishes, ensuring each installation complements the property's design whilst improving comfort, security and long-term reliability.
Learn More →Traditional cottage proportions combined with slim aluminium frames make aluminium cottage windows well suited to rural properties, character homes and modern cottage renovations where classic styling and reduced maintenance are equally important. Durable powder-coated finishes are available in a wide range of RAL colours and dual-colour combinations, allowing internal and external finishes to complement the property's architectural details. Our in-house installers install and replace these windows with thermally broken frames, Low-E glazing, secure locking systems and carefully designed profiles, maintaining traditional charm whilst delivering modern insulation, security and long-term performance.
Learn More →Sympathetic detailing, slim profiles and thermally broken aluminium frames allow aluminium historic windows to recreate traditional period glazing without compromising modern performance. Heritage-inspired renovations, conservation projects and properties where architectural character must be maintained benefit from this approach. Bowalker Windows installs and replaces these windows with carefully specified profiles, Low-E glazing, argon-filled sealed units, durable powder-coated finishes and secure locking systems, with RAL colours and dual-colour finishes available to complement both traditional exteriors and modern interiors.
Learn More →Slim, strong frames and large uninterrupted glazed areas make aluminium picture windows ideal for contemporary homes, extensions and open-plan spaces where maximum natural light and wide outdoor views are priorities. The absence of opening sections allows cleaner sightlines and larger glass areas across the frame. We install and replace these windows with thermally broken aluminium profiles, Low-E glazing, argon-filled sealed units, warm-edge spacer bars and durable powder-coated finishes, creating refined architectural features with excellent insulation, security and long-term performance.
Learn More →Defined glazing bars, slim sightlines and durable aluminium frames make aluminium Crittall-style windows well suited to industrial-inspired interiors, contemporary extensions and period renovations where a structured grid appearance is important. Thermally broken profiles improve insulation whilst maintaining the narrow frame proportions associated with traditional steel windows. Our in-house installers install and replace these windows with secure glazing systems, Low-E glass, warm-edge spacer bars and durable powder-coated finishes, with popular RAL colours such as black, anthracite and grey helping create an authentic steel-look appearance.
Learn More →Double Glazed Aluminium Windows
Double Glazed Aluminium Windows
Without widening the slim frame profile, double glazed aluminium windows reduce heat loss and improve acoustic comfort through two panes of Low-E glass separated by an argon-filled sealed unit and warm-edge spacer bars. Most homes benefit from this combination of energy efficiency, security and clean sightlines. Every double glazed aluminium window we install and replace uses thermally broken frames and carefully sealed glazing units, improving indoor comfort whilst maintaining the refined appearance aluminium frames are known for.
Learn More →Three panes of Low-E glass separated by two insulated cavities, argon filling and warm-edge spacer bars provide triple glazed aluminium windows with enhanced thermal and acoustic performance, making them suitable for exposed properties, busy locations and homes where energy efficiency is a priority. The additional glazing layer helps reduce heat loss and external noise whilst maintaining the strength and slim appearance of aluminium frames. Our experienced in-house installers install and replace these windows with thermally broken frames, high-performance glazing and secure hardware, creating warmer, quieter interiors with improved comfort throughout the year.
Learn More →Bathrooms, entrance halls and ground-floor rooms benefit from obscure glass aluminium windows, where privacy glazing reduces visibility from outside whilst allowing natural daylight to pass through the slim aluminium frame. Different privacy levels and patterned finishes allow homeowners to balance light transmission and visibility according to each room's requirements. We install and replace these windows with privacy-rated glazing, thermally efficient frames and secure hardware, maintaining comfort, natural light and a consistent modern appearance.
Learn More →A smooth acid-etched frosted surface that diffuses daylight evenly whilst limiting direct visibility makes satin glass aluminium windows suitable for bathrooms, offices, hallways and entrance areas where privacy and refined design are priorities. Unlike textured obscure glazing, satin glass provides a consistent finish across the pane. With thermally broken aluminium frames, energy-efficient glazing and accurately aligned profiles, each satin glass window our team installs and replaces achieves a clean, understated finish with dependable long-term performance.
Learn More →Decorative coloured glazing within strong aluminium frames creates a distinctive feature suited to entrance halls, heritage-inspired properties and architectural projects where decorative detail is important. Each installation is planned around surrounding finishes to ensure colour, proportion and frame detailing work together. Bowalker Windows installs and replaces these windows with careful attention to glazing design, frame proportions and installation accuracy, creating attractive features whilst maintaining modern security and thermal performance.
Learn More →Improving thermal and acoustic performance without replacing existing aluminium windows is the key benefit of secondary glazing. A slim internal glazed panel installed behind the existing frame creates an insulating air gap, which can be optimised for thermal and acoustic performance depending on the property and existing window configuration. This makes secondary glazing particularly suitable for conservation areas, listed buildings and period properties where window replacement is restricted. We install secondary glazing using carefully surveyed slim aluminium systems and suitable glazing specifications, improving indoor comfort without altering the property's external character.
Learn More →Fixed Aluminium Windows
Fixed Aluminium Windows
Large glazed areas without opening sections and clean architectural lines define fixed aluminium windows, making them well suited to feature elevations, extensions and rooms where ventilation is managed by surrounding openings. Slim thermally broken aluminium frames allow greater glass areas and uninterrupted views whilst maintaining structural strength. We install and replace these windows with internally beaded glazing, Low-E sealed units, argon-filled insulated cavities, warm-edge spacer bars, secure glazing and durable RAL powder-coated finishes, delivering refined architectural clarity with reliable insulation, security and long-term durability.
Learn More →Casement Aluminium Windows
Casement Aluminium Windows
Side-hung or top-hung opening sections allow casement aluminium windows to provide ventilation whilst maintaining slim frame profiles, making them suitable for modern homes, extensions and renovation projects. Multipoint locking systems and thermally efficient glazing support secure everyday operation. Our in-house installers install and replace these windows with Low-E glazing, secure hardware and accurately aligned frames, ensuring reliable operation and improved thermal performance throughout the year.
Learn More →Two opening functions within a single slim thermally broken frame make tilt-and-turn aluminium windows practical for contemporary homes, apartments and upper-floor rooms where controlled ventilation and easy internal cleaning are priorities. The sash tilts inward at the top for everyday airflow or swings fully open on a side hinge for maintenance access and emergency egress. By specifying secure multipoint locking, precision-engineered mechanisms and energy-efficient glazing, we install and replace these windows with a refined finish that combines flexible operation with the slim sightlines aluminium frames provide.
Learn More →Recreating traditional sash proportions with the durability of modern aluminium frames, vertical sliding aluminium windows suit period-inspired properties and contemporary homes where classic styling and improved performance need to work together. Modern operating systems provide smoother movement with reduced maintenance compared with traditional timber sash mechanisms. Bowalker installs and replaces these windows with energy-efficient glazing, secure locking systems and accurately proportioned frames, preserving character whilst improving insulation and everyday usability.
Learn More →Multiple folding panels that stack neatly to one side create wide openings in bifold aluminium windows, making them well suited to extensions, garden rooms and open-plan spaces where natural light, ventilation and connection with outdoor areas are priorities. Slim aluminium profiles maintain clean sightlines across the opening when closed. Our experienced in-house installers install and replace these windows with precision-engineered hardware, secure multipoint locking systems and durable powder-coated frames, creating practical, light-filled spaces with long-term reliability.

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

Frequently Asked Questions
What Are Aluminium Windows?
Aluminium windows are window systems made from strong, lightweight aluminium frames that provide slim sightlines, large glazed areas and long-term durability. Frames are thermally broken using a polyamide barrier that separates the inner and outer aluminium sections, significantly reducing heat transfer and improving energy efficiency. They are commonly installed in modern homes, extensions and renovated properties because aluminium resists corrosion, retains its powder-coated finish for decades and supports high-performance glazing systems including Low-E double and triple glazed sealed units.
How Long Does Aluminium Window Installation Take?
Aluminium window installation takes 1 to 2 days depending on the number of windows, access requirements, window size and installation complexity. Larger projects involving bespoke designs, structural preparation or multiple replacements may require additional time. Our in-house installers complete every installation with careful measurement and accurate fitting to ensure reliable performance.
How Do You Clean Aluminium Windows?
Clean aluminium windows using warm water, a small amount of mild washing-up liquid and a soft microfibre cloth, working across the frame, sills, glazing bars and rubber seals to remove dirt and grime. Use a non-abrasive glass cleaner for the glazing and avoid bleach, solvent-based products or abrasive pads that can strip or discolour the powder-coated finish. Clearing drainage slots with a soft brush, lubricating hinges and locking mechanisms with a light oil and wiping seals regularly helps maintain smooth operation, weatherproofing and long-term performance.
How Do You Choose the Right Aluminium Windows for Your Home?
Choosing the right aluminium windows starts with your property’s architectural style, then considers frame profile, glazing specification, colour finish and energy-efficiency requirements. Slim-profile aluminium windows suit contemporary designs, whilst heritage-style aluminium profiles complement period properties. During your consultation, we assess your property and recommend aluminium windows that balance appearance, performance and long-term durability.
What Aluminium Window Design Ideas Should You Consider for Your Home?
Picture windows that maximise views, bifold systems that blur the boundary between indoors and outdoors, flush frames that sit cleanly within the building line and Crittall-style grid glazing that adds industrial character are the design ideas most worth considering for aluminium windows. Opening configuration should be selected to suit ventilation requirements and room use. Coordinating RAL colour finishes across windows, doors and external features creates a consistent and considered appearance throughout the property.
What Guarantee Do You Provide on Aluminium Window Installation?
Bowalker provides a 10-year insurance-backed guarantee on qualifying aluminium window installation and replacement work. Our FENSA registration (Reg. 33081) confirms that applicable replacement installations meet current Building Regulations for thermal performance, ventilation and safety. We provide the relevant certification after completion, giving homeowners confidence in the quality of the installation.
