Triple glazed French doors for homes in Penzance: measured on a free survey, made to order and fitted by installation teams working for us across Cornwall.

Winter light and glass choice in Penzance
Winter days in Penzance are short: about 8 h 03 min of daylight on 21 December, with the sun peaking near 16°. That low angle reaches deep into south-facing rooms, so we match the glass to each elevation rather than using one spec for the whole house.

Rules for french doors in England
England sets replacement door limits through Approved Document L (2021 edition, with 2023 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: a competent person scheme installer (such as FENSA or Certass) self-certifies the work and notifies the council, or a building control body approves it.
Before ordering: Replacing doors on a house is normally permitted development if the new ones look similar. Flats need planning permission for a change that alters their appearance, an Article 4 direction may mean permission is needed, and listed buildings need listed building consent.
How it works
You will know exactly what you are buying: the quote states the unit build-up, frame, finish, fitting work and how Building Regulations compliance is handled. On fitting day each opening is replaced and closed up before the team moves on.
