Triple glazed bifold doors in Folkestone
Triple glazed bifold doors for homes in Folkestone: measured on a free survey, made to order and fitted by installation teams working for us across Kent.
Folding aluminium doors with three panes in every panel. 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 Folkestone
By midsummer Folkestone has about 16 h 34 min of daylight, but in December only around 7 h 54 min, with the noon sun at about 16°. 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.
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.
- Every opening measured, including escape and vent needs
- Frames rated for the weight of triple glass
- Old windows removed and taken away
- Each opening closed up the same day
