Triple glazed timber windows in Glasgow and the Clyde
We survey and fit triple glazed timber windows across Glasgow and the Clyde, from Glasgow and Paisley to smaller towns such as Bishopbriggs.
The usual choice for period homes and conservation areas. Triple glazed timber windows are made from engineered (laminated) timber, which resists warping, and glazed with a three-pane sealed unit.

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.
Planning: 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.
- Free survey and a written quote fixed for the specification
- Glass build-up and whole-window U-value on every quote
- Written handover pack at the end of the job
- Guarantees on frames, units and fitting in writing
Questions
Do timber windows need planning permission?
Replacing like-for-like windows on a house is normally permitted development, but conservation areas, Article 4 directions and listed buildings have their own rules. See our planning guide.
Can I get triple glazed timber sash windows?
Yes, though not every sash design can take a full-thickness triple unit. Where the box and sash sizes limit the unit, we tell you the U-value you will actually get.
How long do timber windows take?
Usually 6 to 10 weeks from survey because each window is made to order and finished in the factory. We never quote less than 5 weeks for timber.
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 timber 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.
