Triple glazed bay and bow windows in Aberdeen and Aberdeenshire
Homes across Aberdeen and Aberdeenshire, including Aberdeen, Peterhead and Ellon, can have triple glazed bay and bow windows measured, made to order and fitted.

Rules in Scotland
Scotland requires replacement windows to achieve 1.6 W/m²K, which good triple glazing passes comfortably. 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
