Triple glazed bay and bow windows in Glasgow and the Clyde
Homes across Glasgow and the Clyde, including Glasgow, Paisley and Bishopbriggs, can have triple glazed bay and bow windows measured, made to order and fitted.

Three- and five-light bays, structure checked and supported. A bay window projects out from the wall in angled sections; a bow window curves in more, shallower sections.

Rules in Scotland
The rules for replacement windows in Scotland are set by the Building Standards Technical Handbook (Domestic), section 6: 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
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.

Questions
Do bay windows need bay poles?
If the old frames carry load from above, yes. We check on survey and include support in the quote where needed.
Can I change a bay to a flat window?
That is a structural and planning change, not a like-for-like replacement. Ask and we will explain what it involves.
Will the bay be warmer?
Yes. Replacing old double or single glazing in a bay with triple glazing cuts heat loss through the glass and makes the glass surface warmer, so the room feels less draughty.
Do you cover all of Glasgow and the Clyde?
We arrange surveys and fitting across Glasgow and the Clyde.
Do I need permission for triple glazed bay and bow windows in Scotland?
In Scotland, replacement windows on houses are widely permitted development since May 2024, with front elevations expected to match closely; listed buildings need consent.
