Alu-clad timber triple glazed windows in Truro
Looking at alu-clad timber triple glazed windows for a home in Truro? We survey, quote and fit across Cornwall, and the TR1 postcode district is part of that.

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 Truro
Winter days in Truro are short: about 8 h 02 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 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.
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.

Questions from Truro
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.
Can I choose different colours inside and out?
Yes. The aluminium can be any RAL colour and the timber inside can be natural, stained or painted.
