Thermally broken aluminium carries heavy triple glass in slim frames, in any RAL colour. 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 Watford

By midsummer Watford has about 16 h 40 min of daylight, but in December only around 7 h 48 min, with the noon sun at about 15°. 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 aluminium windows in England

England requires replacement windows to achieve 1.4 W/m²K, or a Window Energy Rating of band B or better, which good triple glazing passes comfortably. 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.

Planning: 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

We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.

  • 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 Watford

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.

Do I need permission for triple glazed aluminium windows in Watford?

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.
