Alu-clad timber windows · Isle of Wight
Alu-clad timber triple glazed windows in Cowes
We take enquiries for alu-clad timber triple glazed windows in Cowes. Because PO31 is a remote or island district, surveys and fitting are by arrangement, with travel costs agreed before you commit.

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 Cowes
Winter days in Cowes are short: about 7 h 57 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
In England, replacement windows must meet 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.
- 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 Cowes
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 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.
Do you fit alu-clad timber triple glazed windows in Cowes?
By arrangement. Cowes (PO31) is a remote or island district, so we confirm availability before booking a survey and show any travel or access costs separately on your quote.
Do I need permission for alu-clad timber triple glazed windows in Cowes?
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.
