Sunlight, glass and orientation in Finchley
Sun angles matter for big glazed doors. Around Finchley, 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.
From guide price to fitted door in Finchley
Every job in the N3 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 England
In England, a replacement sliding door is a controlled fitting under the Building Regulations. In an existing home, a door with more than 60% glazing must reach a U-value of 1.4 W/m²K or better (or a Doorset Energy Rating of band C) under Approved Document L, and glass in doors must be safety glazing under Approved Document K. We arrange compliance through a competent person scheme installer or by notifying Building Control, and you receive the certificate.
