Alu-clad timber triple glazed windows in Blackburn
From the first measure to the handover pack, we handle alu-clad timber triple glazed windows for homes in Blackburn and the rest of Lancashire.

The low-upkeep, high-performance frame many self-builders choose. Alu-clad (aluminium-clad) timber windows have a structural timber frame inside and a powder-coated aluminium cladding outside, glazed with a three-pane unit.
Winter light and glass choice in Blackburn
By midsummer Blackburn has about 17 h 05 min of daylight, but in December only around 7 h 25 min, with the noon sun at about 13°. Triple glazing keeps more heat in during those long, dark months; big south and west windows may suit solar-control glass for summer.

Rules for alu-clad timber windows in England
In England, replacement windows must meet 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
After the free survey you get a written quote naming the frame system, the glass build-up and the whole-window U-value for every item. Windows are made to order, then fitted, sealed and made good, one opening at a time.
- 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 Blackburn
Is alu-clad timber worth the extra cost?
It is for many self-builders and people planning to stay for decades, because the outside needs almost no upkeep and the timber inside looks warm. For a quick replacement on a typical semi, uPVC or aluminium give better value.
Can I choose different colours inside and out?
Yes. The aluminium can be any RAL colour and the timber inside can be natural, stained or painted.
Do I need permission for alu-clad timber triple glazed windows in Blackburn?
In England, like-for-like replacements on a house are normally permitted development; flats need permission if the change alters their appearance, Article 4 areas may need permission, and listed buildings need listed building consent. Check whether your street is in a conservation area or covered by an Article 4 direction before changing the style.
