Slim anthracite aluminium windows on a contemporary rendered and clad house

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 Portslade

Winter days in Portslade are short: about 7 h 56 min of daylight on 21 December, with the sun peaking near 16°. 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.

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

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 Portslade

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.

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 Portslade?

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 Portslade?

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