A warmer hallway: triple glass where front doors lose most heat. A composite front door has a solid insulated core, usually timber or foam, under a tough glass-reinforced plastic (GRP) skin, with a multi-point lock.
Winter light and glass choice in Mangotsfield
By midsummer Mangotsfield 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 composite front 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

Questions from Mangotsfield
Are composite doors secure?
Good ones are tested to PAS 24 and fitted with anti-snap cylinders. We specify both.
Is triple glazing worth it in a front door?
The glass is the weakest part of a composite door for heat loss, so triple glazing the panels helps most when the door has large glazed areas or side panels.
Do I need permission for triple glazed composite front doors in Mangotsfield?
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.
How long does it take to get triple glazed composite front doors fitted in Mangotsfield?
After the survey, typical manufacture time is 4 to 6 weeks, and a door is usually fitted in a day.
