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 Castle Douglas

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

You will know exactly what you are buying: the quote states the unit build-up, frame, finish, fitting work and how Building Regulations compliance is handled. On fitting day each opening is replaced and closed up before the team moves on.

Questions from Castle Douglas

Can I have a level threshold?

Low thresholds are available; they need a suitable drainage detail outside, which we check on survey.

Are triple glazed sliding doors hard to open?

Not with correctly rated rollers. Lift-and-slide gear makes even very large panels easy to move.

Do I need permission for triple glazed sliding patio doors in Castle Douglas?
