Triple glazed sliding patio doors in Northampton
Triple glazed sliding patio doors for homes in Northampton: measured on a free survey, made to order and fitted by installation teams working for us across Northamptonshire.
Large sliding panels in triple glass on rollers rated for the weight. A sliding patio door has large glazed panels that slide past each other on a track, so it opens without swinging into the room.
Winter light and glass choice in Northampton
Winter days in Northampton are short: about 7 h 42 min of daylight on 21 December, with the sun peaking near 14°. 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 sliding patio doors in England
In England, replacement external doors must meet 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
The surveyor measures every opening, checks ventilation, escape windows and safety-glass zones, and talks through styles. Your written quote lists each item with its glass build-up and U-value, and the price is fixed for that specification.
