Triple glazed aluminium windows in Derby
We arrange surveys and fitting of triple glazed aluminium windows in Derby and the DE1 area, with a written, fixed quote after a free survey.

Slim sightlines and a powder-coated finish, with three panes of glass. Triple glazed aluminium windows use thermally broken aluminium frames, where an insulating strip separates the inside and outside of the frame, holding a three-pane sealed unit.
Winter light and glass choice in Derby
Winter days in Derby are short: about 7 h 34 min of daylight on 21 December, with the sun peaking near 14°. That low angle reaches deep into south-facing rooms, so we match the glass to each elevation rather than using one spec for the whole house.

Rules for aluminium windows in England
The rules for replacement windows in England are set by Approved Document L (2021 edition, with 2023 amendments): 1.4 W/m²K, or a Window Energy Rating of band B or better. Replacement windows are a controlled fitting. A competent person scheme installer (such as FENSA or Certass) self-certifies the work and notifies the council within 30 days; otherwise a building control body approves it.
Before ordering: Replacing windows on a house is normally permitted development if the new ones look similar. New upper-floor windows in a side wall must be obscure glazed and fixed, or open only above 1.7 m. Flats and maisonettes have no householder permitted development rights, so a change that alters their appearance needs planning permission. An Article 4 direction in a conservation area may mean permission is needed, and listed buildings need listed building consent.
How it works
You will know exactly what you are buying: the quote states the unit build-up, frame, finish, fitting work and how Building Regulations compliance is handled. On fitting day each opening is replaced and closed up before the team moves on.
- Every opening measured, including escape and vent needs
- Frames rated for the weight of triple glass
- Old windows removed and taken away
- Each opening closed up the same day
Questions from Derby
Can aluminium windows take triple glazing?
Yes, and the strength of aluminium suits the extra weight. The system needs a glazing rebate deep enough for the unit, which we check on survey.
Do aluminium windows suit older houses?
They suit many 20th-century homes well. For Victorian and Georgian houses, or conservation areas, timber or heritage-style frames are usually a better match.
How long does it take to get triple glazed aluminium windows fitted in Derby?
After the survey, typical manufacture time is 5 to 7 weeks, and most homes are fitted in 1 to 4 days.
