Aluminium Windows for Colchester homes and sites
Windows are usually a whole-house order rather than a single opening, so colour consistency and accurate measurements matter more than lead time. Ordering every window together is the simplest way to keep the colour and finish consistent across the property.
We supply aluminium windows across the CO postcode area and the rest of Essex, including Ipswich (16 miles north-east), Chelmsford (21 miles west-south-west) and Southend-on-Sea (26 miles south-south-west).We manufacture and deliver — your own installer or builder does the fitting.
Colchester carries a lot of period and conservation-area stock, so colour and section profile tend to matter more here than raw specification. RAL colours and heritage-style doors are both available — check with the local planning office before you order.

Aluminium Windows in Colchester — questions we get asked
What U-value can I get on aluminium windows in Colchester?
From 1.4 W/m²K, depending on the glass specification. The Building Regulations limit for replacement windows in England is 1.4 W/m²K, so choose the glass with that in mind — ask us for the figure for your chosen build-up.
Can I have different colours inside and out?
Yes — dual-colour (a different colour inside and out) is available at no extra charge on stock finishes. A dark exterior with a white interior is a common combination.
