Triple glazed sliding patio doors in Forfar
From the first measure to the handover pack, we handle triple glazed sliding patio doors for homes in Forfar and the rest of Angus and Dundee.

Large sliding panels in triple glass on rollers rated for the weight. A sliding patio door has large glazed panels that slide past each other on a track, so it opens without swinging into the room.
Winter light and glass choice in Forfar

Rules for sliding patio doors in Scotland
In Scotland, replacement external doors must meet 1.6 W/m²K. Replacing a door or window, frame and all, does not need a building warrant, but the work must still meet the building standards.
Planning: A replacement door on a house that looks similar to the existing one is generally permitted development; check with your council for flats and conservation areas, and 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
