FAQs
How do 3 panel bifold doors open?
The three panels are hinged together and glide along a track, folding and stacking to one side to create a wide, unobstructed opening. The three-panel layout also lets you open
just part of the set — using a single panel as an everyday access door — or fold all three back to fully open your space.
What size are 3 panel bifold doors?
They're made to measure to fit your opening, available in heights up to 2200mm, 2400mm and 2600mm. With each of the three panels up to 1200mm wide, a 3 panel set spans up to around 3.6m in total width, configured precisely to your space.

Are aluminium bifold doors good?
Yes — aluminium is one of the best materials for bifold doors. It's strong enough to carry large panes of glass with slim 107mm sightlines, is corrosion-resistant, low-maintenance and long-lasting, and delivers excellent thermal performance with U-values as low as 1.1 W/m²K. Ours are backed by a 10-year warranty.
How secure are 3 panel bifold doors?
Our bifold doors come with 6-point locking and toughened glass as standard, with PAS 24 certification available as an option, all set within a robust aluminium frame designed for external security.
How energy efficient are they?
They achieve U-values as low as 1.1 W/m²K and a Door Energy Rated (DER) band B, using thermally broken aluminium profiles and high-performance glazing from 28mm to 44mm (double or triple) to keep heat in and reduce energy bills.
Are 3 panel bifold doors weatherproof?
Yes. Our bifold doors are independently rated for UK weather, achieving Class 4 for air permeability, Class 9A for water tightness and Class A3 for wind load resistance — so they stay draught-free, watertight and stable even in exposed conditions.
What colours are available?
Our 3 panel bifold doors come in three standard colours — black, anthracite grey and white — with custom RAL colours available on request to match any property.
