Inspired Glazing installs uPVC windows in Colnbrook using the Selecta Advance 70 profile, with double or triple glazed units chosen to cut aircraft and motorway noise as well as heat loss. We travel from our Fifield workshop near Windsor, a trip of roughly 20 to 25 minutes along the M4, and fit with our own team.

Living between Heathrow and two motorways
Colnbrook sits in the far east of Slough, inside a rough triangle formed by M4 Junction 5, M25 Junction 14 and the interchange where the two motorways meet. Heathrow is on the doorstep, and the parish council itself notes that the airport brings aircraft noise as well as business. For most households here, the first question about double glazing in Colnbrook is how much quieter a new window can make a bedroom.
The honest answer is that the glass does most of the work. A 40mm triple glazed unit, which the Advance 70 frame accepts, improves acoustic performance compared with standard double glazing, and laminated or unequal-thickness panes can help further. Good seals and careful fitting matter just as much, because sound finds any gap. Our page on sound-reducing windows explains the options in more detail, and where frames must stay, secondary glazing adds a second barrier on the inside.
Old coaching inns and newer estates
Colnbrook grew as a string of coaching inns on the old Bath Road, and by 1577 it had ten of them. The Ostrich Inn, a Grade II* listed building, still stands on the High Street. Behind the historic core are later housing developments, and Brands Hill and Poyle complete the parish, with Poyle being largely industrial.
- Cottages and older houses near the High Street look best with flush casements or uPVC sash windows in the flush sash style, which has a 4mm sightline between sash and frame.
- Post-war and modern family homes suit standard casements, with bay windows rebuilt where the original had them.
- Flats and upstairs rooms often benefit from tilt and turn windows for safe cleaning and night ventilation.
Cottage-style or shaped windows can sometimes be made in the same profile; ask us to confirm for your elevation.
The Selecta Advance 70 frame
The Advance 70 system is a 70mm uPVC profile with five thermal chambers, plus an optional 80mm traditional outer frame with eight chambers. Selecta gives a U-value of 1.1 W/mยฒK with a 28mm double glazed unit and 0.8 W/mยฒK with a 40mm triple unit. Its casements are tested to PAS 24 and Secured by Design, so window security is built in rather than added later. For more on energy bands, read about energy-rated windows, and ask us to confirm the rating for the units we specify.
Colours and finishes
White is still the most common choice, but there are 18 Colourfoil finishes in total, on one face or both. Anthracite Grey, Slate Grey and Ulti-Matt Black give a modern edge, while Golden Oak and Mountain Oak offer a timber look without the upkeep of real wood, which we do not install. Our window colours page shows the range.
Doors for front, back and garden
Advance 70 doors are rated to PAS 24:2016 and take multi-point locks in full-depth Eurogrooves. Choose full glass, full panel, or half glass with a midrail, with side screens and top lights if you want more light in the hallway. Look through our front doors, or compare them with composite doors, which have a solid core. Back doors and French doors open the kitchen or lounge to the garden, and stable doors are worth asking about for a utility room. For a wider opening, aluminium sliding patio doors are another route. We can also discuss smart lock options for keyless entry.
Is it time to replace?
Condensation between panes, handles that will not lock and frames that let in draughts are all reasons to look at replacement. We assess each window and tell you whether a new unit or a whole new frame is the better route. The factors behind a quotation are explained in our guide to double glazing cost.
Conservation rules in Colnbrook
Slough Borough Council lists Colnbrook as one of its five conservation areas, and there are listed buildings along the old High Street.

Frequently asked questions
Will new windows block out Heathrow aircraft noise?
No window removes aircraft noise completely, but the right glass makes a clear difference. Triple glazing or laminated acoustic units reduce more sound than standard double glazing, and tight seals stop noise leaking around the frame. Many Colnbrook households begin with the bedrooms, where quieter nights matter most.
How long does it take you to reach Colnbrook?
Colnbrook is a little over seven miles from our base in Fifield as the crow flies. By road that usually means 20 to 25 minutes via the M4, though motorway traffic around Junction 5 can stretch it. Surveys are booked at a time that suits you, including Saturday mornings.
Is Colnbrook a conservation area?
Part of it is. Slough Borough Council names Colnbrook among its conservation areas, and several buildings on the historic High Street are listed. If your property is inside the boundary or listed, the rules on changing windows may be stricter, so check with Slough Borough Council before you commit to new frames or doors.
Can I have grey windows on a house in Colnbrook?
Yes. Anthracite Grey, Slate Grey, Agate Grey and Hazy Grey are all available in the Selecta Colourfoil range, either outside only or on both faces. Grey suits modern homes and contrasts well with white render. In a conservation area, check with Slough Borough Council whether a colour change needs approval first.
Do you fit secure back doors and patio doors?
We do. Our uPVC doors are on a system rated to PAS 24:2016, with multi-point locking. For patios, uPVC French doors suit narrower openings, and aluminium sliding doors suit wider ones. Composite back doors are another option if you want a solid, heavy door with a timber-effect finish.
