Triple glazed composite front doors in Llantwit Major
From the first measure to the handover pack, we handle triple glazed composite front doors for homes in Llantwit Major and the rest of South Glamorgan.
A warmer hallway: triple glass where front doors lose most heat. A composite front door has a solid insulated core, usually timber or foam, under a tough glass-reinforced plastic (GRP) skin, with a multi-point lock.
Winter light and glass choice in Llantwit Major
By midsummer Llantwit Major has about 16 h 37 min of daylight, but in December only around 7 h 50 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 composite front 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
We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.
- 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
