Sunlight, glass and orientation in Carmarthen
Sun angles matter for big glazed doors. Around Carmarthen, midday sun reaches about 62° in summer and drops to about 15° in winter. That low winter sun is free heat through south-facing glass; high summer sun is easier to shade with a roof overhang, and solar-control glass helps where there is none.
How it works in Carmarthen
Start with a guide price online or by phone. A surveyor then measures your opening in Carmarthen, checks levels and the lintel, and you receive a fixed written quote. After you approve it, the door is made to measure and fitted, with the compliance certificate sent to you.
Approvals in Wales
Wales sets its own Building Regulations guidance, including Approved Document L (Wales) for energy. A replacement sliding door must meet those requirements and use safety glass, and we arrange compliance through a registered installer or the local Building Control service.
