Alu-clad timber triple glazed windows in Stirling
From the first measure to the handover pack, we handle alu-clad timber triple glazed windows for homes in Stirling and the rest of the Forth Valley.

Timber inside, aluminium outside, three panes of glass between. 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 Stirling
In Stirling, midday sun in late December sits around 10° high, with roughly 6 h 55 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 alu-clad timber windows in Scotland
In Scotland, replacement windows must meet 1.6 W/m²K. Replacing a window or door, frame and all, does not need a building warrant, but the work must still meet the building standards.
Before ordering: Since May 2024, replacement windows on houses are widely permitted development, including in many conservation areas, with front elevations expected to match the existing closely; your council tells you if prior notification applies. Flats outside conservation areas generally need permission only if the opening size changes. 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
