More glass, less cold: sliders that stay comfortable in winter. 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 Heston

By midsummer Heston has about 16 h 38 min of daylight, but in December only around 7 h 50 min, with the noon sun at about 15°. Triple glazing keeps more heat in during those long, dark months; big south and west windows may suit solar-control glass for summer.

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

We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.

  • 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

Questions from Heston

Can I have a level threshold?

Low thresholds are available; they need a suitable drainage detail outside, which we check on survey.

Yes, all door glass must be safety glass. Triple units in sliders are toughened or laminated.

Do I need permission for triple glazed sliding patio doors in Heston?

In England, a replacement door on a house that looks similar is normally permitted development; flats need permission if the change alters their appearance, Article 4 areas may need permission, and listed buildings need listed building consent. Check whether your street is in a conservation area or covered by an Article 4 direction before changing the style.
