Daylight in Blackwood and what it means for your glass
Sun angles matter for big glazed doors. Around Blackwood, 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.
What happens after you enquire
Every job in the NP12 district follows the same steps: price online, survey, written quote, made-to-measure manufacture and fitting, 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.
