Warm timber in the room and a weatherproof shell to the weather. 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 Derby

Winter days in Derby are short: about 7 h 34 min of daylight on 21 December, with the sun peaking near 14°. 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 alu-clad timber 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

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.

  • No pressure: the quote is yours to keep

Questions from Derby

Do alu-clad windows suit Passivhaus builds?

Many alu-clad systems are designed for low-energy homes. If you need Passive House Institute certified components, ask and we will price systems that hold that certification.

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.

Do you fit alu-clad timber triple glazed windows in Derby?

Yes. We arrange surveys and fitting in Derby and across Derbyshire. Send your postcode and the windows or doors you want replaced, and we will book a free survey.
