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 Gainsborough

Winter days in Gainsborough are short: about 7 h 29 min of daylight on 21 December, with the sun peaking near 13°. 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

After the free survey you get a written quote naming the frame system, the glass build-up and the whole-window U-value for every item. Windows are made to order, then fitted, sealed and made good, one opening at a time.

  • Free survey and a written quote fixed for the specification
  • Glass build-up and door U-value on every quote
  • Written handover pack at the end of the job
  • Guarantees on frames, units and fitting in writing
