Triple glazed sliding patio doors in Brecon
We arrange surveys and fitting of triple glazed sliding patio doors in Brecon and the LD3 area, with a written, fixed quote after a free survey.

More glass, less cold: sliders that stay comfortable in winter. 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 Brecon
By midsummer Brecon has about 16 h 43 min of daylight, but in December only around 7 h 45 min, with the noon sun at about 15°. Triple glazing keeps more heat in during those long, dark months; big south and west windows may suit solar-control glass for summer.

Rules for sliding patio doors in Wales
Wales sets replacement door limits through Approved Document L for Wales (2022 edition, with 2024 amendments): 1.4 W/m²K, or a door set energy rating of band C (more than 60% glazed) or band B (other doors). Replacement external doors fall under the same energy rules as windows: a competent person scheme installer self-certifies the work, or building control approves it.
Before ordering: Householder permitted development rules do not cover flats, and councils can remove rights with Article 4 directions. Listed buildings need listed building consent. Check with your council before changing the style or material of a front door.
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.
- 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
