Triple glazed bifold doors in Thetford
From the first measure to the handover pack, we handle triple glazed bifold doors for homes in Thetford and the rest of Norfolk.
Slim, strong bifolds rated for heavy triple glass. Bifold doors are made of several panels hinged together that fold and slide to one or both sides, opening almost the full width of the opening.
Winter light and glass choice in Thetford
By midsummer Thetford has about 16 h 49 min of daylight, but in December only around 7 h 40 min, with the noon sun at about 14°. 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 bifold 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.
Planning: 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.

Questions from Thetford
Are bifolds warmer with triple glazing?
Yes. The glass is most of the door area, so triple units cut heat loss and keep the inner surface warmer.

Replacing an existing door is covered by the replacement rules. A new or widened opening is structural work that needs building control approval.
