Why aluminium is the only bifold worth fitting
A bifold door is mostly hinge and roller: each leaf hangs off the next and the whole run concertinas onto stainless steel wheels in a top or bottom track. That hardware punishes weak frames. Aluminium is rigid enough to carry a 1.2m wide, toughened double-glazed leaf on a slim profile without dropping or twisting through London's damp winters, which is why uPVC bifolds have all but disappeared from the market.
Ours are thermally broken (a polyamide barrier through the frame stops cold tracking indoors), achieve around 1.4 W/m²K double glazed, and are powder-coated in any RAL colour, with anthracite grey 7016 and jet black 9005 the runaway London favourites. A slim bifold option trims the meeting stiles to roughly 90-100mm where two leaves join, so even a closed set reads as glass, not frame.

How should your bifold fold?
Configuration is the decision that matters most and the one showrooms rush. It sets where the leaves stack, which way they swing, and whether you have a normal door for taking the bins out in January. We sketch these options against your actual opening at the free survey.
From survey to first fold in 2-3 weeks
Because the frames are fabricated by our sister company Prime Fabrication, factory direct, no middleman, we control the whole chain: the surveyor who measures your opening briefs the fabricator who makes the doors and the fitter who hangs them. Nothing is lost between three different firms, and a remake, if ever needed, takes days rather than a season.
Free survey
We measure the structural opening, check the lintel and levels, and talk through configurations, thresholds and colours. Fixed quote follows in writing.
Fabrication
Profiles are cut, crimped and powder-coated to your RAL, then glazed with 28mm argon-filled toughened units. Typically 2-3 weeks.
Fitting day
Old doors out, new track levelled to the millimetre (bifolds live or die by a level track), leaves hung, adjusted and sealed. Usually one day.
FENSA sign-off
Installation is registered with FENSA, so your Building Regulations certificate and guarantee paperwork arrive without you lifting a finger.
Your bifold is made in our own factory
Most London installers buy bifold sets from a national trade fabricator and add a margin. Ours come from Prime Fabrication, the fabrication company in our own group, so you buy factory direct with no middleman. That is why our lead times run 2-3 weeks instead of the industry's 6-8, why odd-sized openings cost no drama, and why builders and developers ask us for supply-only sets from the same line.
