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 Portsmouth

In Portsmouth, midday sun in late December sits around 16° high, with roughly 7 h 56 min of daylight. For windows facing north or shaded by neighbours, cutting heat loss matters more than solar gain; on open south-facing glass, ask about a higher solar-gain unit.

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.

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 Portsmouth

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.

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.

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

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