Aluminium Windows in Windsor

We make and fit aluminium windows for homes in Windsor, fabricating every frame at our Fifield workshop on Coningsby Lane, about four miles west of the town. The drive into Windsor usually takes around fifteen minutes, so surveys and fitting slot easily into the working day, and the team who build your windows are the team who install them.

A town of townhouses, villas and riverside cottages

Windsor’s character comes in layers. Close to the Castle, Georgian and early Victorian townhouses line streets such as Park Street and Sheet Street; around Trinity Place and Clarence Crescent there are nineteenth-century stuccoed villas and terraces; Clewer and Dedworth grew with interwar and post-war semis; and newer flats have appeared near both railway stations. Across the river, Eton keeps its narrow historic frontages, while Datchet and Old Windsor mix village cottages with larger detached homes.

Aluminium earns its place across that variety because the frames can be made very thin without losing strength. On a Victorian terrace that means more glass and less frame in each opening; on a 1950s semi it means a crisp, contemporary face that lasts for decades without painting.

Planning in the Royal Borough

The Royal Borough of Windsor and Maidenhead has designated Inner Windsor, Windsor Town Centre, Trinity Place/Clarence Crescent, Mill Lane (Clewer Village), Eton, Datchet and Old Windsor as conservation areas, and many buildings near the Castle are listed. In those places a change of window style, material or opening type can need consent, so check with the Royal Borough of Windsor and Maidenhead before committing. Windsor also has plenty of converted flats and apartment blocks: flats have no householder permitted development rights, and a leaseholder usually needs the freeholder’s written consent as well. We explain the basics in our planning guide for replacement windows.

Heritage-sensitive aluminium

Where a slim, traditional look matters, we tend to suggest flush casement windows or heritage-profile Reynaers SL68 windows, finished in a muted shade such as off-white, cream or soft grey. Reynaers quotes a U-value of 1.1 W/m²K for the system, so a draughty period house can gain real warmth. Where a listed building rules out replacement altogether, secondary glazing fitted inside the original frames is a practical fallback that keeps the historic windows untouched while cutting draughts and noise. Crittall-style steel-look aluminium windows suit Arts and Crafts and 1930s houses, which often had metal windows originally, and we also offer Cortizo and Alunet systems as alternatives.

Aircraft, traffic and the Thames

Windsor lies west of Heathrow, and when the airport runs easterly operations, arriving aircraft line up over the town, Datchet and Old Windsor. Add the M4 to the north and trains on the branch lines into Windsor’s two stations, and acoustic glazing becomes a sensible upgrade for bedrooms. Reynaers rates SlimLine 68 at up to 47 dB of sound reduction, and our sound reduction page explains how laminated acoustic glass and triple glazing compare.

Large parts of Datchet, Old Windsor and the low-lying streets near the river fall within the Thames floodplain. For doors on those homes, we pay close attention to threshold heights and drainage when planning the installation.

Choosing between aluminium and uPVC in Windsor

For most period homes in the town, aluminium gives the slimmer face and wider colour choice that both owners and conservation officers tend to prefer. uPVC can still make sense for a rental flat or a modern estate home where cost leads the decision, and we fit uPVC windows and doors in Windsor as well. Our comparison of aluminium and uPVC casements sets out the trade-offs.

Patio, bifold and front doors

Houses on the southern side of town, towards the Great Park, often have gardens that suit a glass wall at the rear. We install Reynaers ConceptPatio 130 sliders, Smart Visofold and Cortizo bifold doors, and aluminium front doors in any RAL shade. Black and anthracite work well against Windsor’s red brick; browse our grey and black frames to compare. Inside, Crittall-style glazed screens and internal steel-look doors divide a kitchen-diner without losing light. For bigger projects, see Windsor conservatories or our main Windsor windows page, and the complete list of aluminium products.

We work across central Windsor, Clewer, Dedworth, Eton, Eton Wick, Datchet and Old Windsor. Neighbouring pages cover Maidenhead and Egham, and the Berkshire area page shows everywhere else we fit.

Frequently asked questions

Can I fit aluminium windows in a Windsor conservation area?

Usually yes, provided the design respects the building. Windsor's conservation areas include Inner Windsor, Windsor Town Centre, Trinity Place/Clarence Crescent and Mill Lane in Clewer. Slim heritage profiles and flush casements tend to sit comfortably in older facades, but consent may be needed for changes to style or material, so check with the Royal Borough of Windsor and Maidenhead first.

Will acoustic glass help with Heathrow aircraft noise in Windsor and Datchet?

It makes a clear difference. On easterly operations, aircraft approaching Heathrow pass over Windsor, Datchet and Old Windsor. Acoustic laminated glass, ideally with unequal pane thicknesses, reduces that noise considerably, and Reynaers rates SlimLine 68 at up to 47 dB of sound reduction. We can suggest the right glass for each bedroom during your survey.

I own a flat in Windsor. Is switching to aluminium windows allowed?

Flats have no householder permitted development rights, so window changes may need planning permission, especially in a conservation area. Most leases also require the freeholder's written consent before external changes. We recommend checking both with your managing agent and the Royal Borough of Windsor and Maidenhead, and we can provide product details to support your request.

Are Crittall-style windows suitable for 1930s houses in Windsor?

Very often. Many houses from that era were built with metal windows, so a Crittall-style steel-look aluminium window brings back the slender glazing bars while adding modern double glazing. They are made in aluminium, not steel, which keeps them lighter and easier to maintain. We also fit matching internal Crittall-style doors and screens.

How long does it take to get aluminium windows installed in Windsor?

Lead times run from 10 days after the survey and final measurements, depending on the system, colour and glass you choose. Because our Fifield workshop is about fifteen minutes from Windsor, fitting days are straightforward to arrange, and the same team handles fabrication and installation, backed by our 10-year guarantee.
