Slim anthracite aluminium windows on a contemporary rendered and clad house

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 Deal

Winter days in Deal are short: about 7 h 52 min of daylight on 21 December, with the sun peaking near 15°. 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

The surveyor measures every opening, checks ventilation, escape windows and safety-glass zones, and talks through styles. Your written quote lists each item with its glass build-up and U-value, and the price is fixed for that specification.

Questions from Deal

Are aluminium windows cold?

Not if the frame has a proper thermal break. Modern thermally broken systems with triple glass reach whole-window U-values around 1.0, well inside the Building Regulations limit for replacement windows.

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 I need permission for triple glazed aluminium windows in Deal?

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.

How long does it take to get triple glazed aluminium windows fitted in Deal?

After the survey, typical manufacture time is 5 to 7 weeks, and most homes are fitted in 1 to 4 days.
