2–7 PANELS · MADE TO MEASUREAluminium bi-fold doors, supply only
Full bi-fold door sets — frame, panels, glass, gaskets and hardware — made to your structural opening and supplied at trade prices, ready for your own fitter to install.
Bi-folds are the door everyone prices three times: once from a national brand's showroom, once from a local installer, and once — if they find us — direct from a manufacturer. The product is often near-identical; the difference is who's in the chain. Supply-only means you pay for the doors, not the showroom.
Give us your structural opening sizes and we'll build the set to fit: two panels for a modest opening, up to seven for a full-width rear elevation. Configurations are made to order — folding left, right or split from the centre, opening in or out, with a traffic door if you want everyday access without concertina-ing the whole wall.
Every set arrives complete: outer frame, panels with toughened double-glazed units, cill, gaskets, rollers and handles. Your fitter installs; nothing extra to source.
Slim frames, big glass
Aluminium is the point here — the strength to carry large glass on slim sightlines that uPVC can't match. The result is more daylight per opening and a flatter, more architectural look, with the rigidity to keep panels running true for years.
Configured around how you'll live with it
Odd or even panel counts, stacking direction, in-swing or out-swing, and a lead traffic door for popping out without opening the run — every set is configured to your opening and your habits. If you're unsure what works for your sizes, send them over and we'll lay out the options with your price.
Thresholds and weather performance
Choose a standard rebated threshold for full weather performance, or a low-profile threshold where a flush, step-free transition matters more — a common choice for level access and indoor-outdoor patios. Multi-point locking and internally beaded glazing come as standard.

Aluminium Bi-Fold Doors — questions we answer daily
What sizes do you need to quote bi-fold doors?
The structural opening — width and height of the brickwork aperture — plus how many panels you'd like and which way they should fold. If you're not sure on panel count, send the opening sizes and we'll recommend configurations with prices for each.
Do supply-only bi-folds come with glass?
Yes. Every set is supplied complete with toughened double-glazed units, along with the frame, cill, gaskets, rollers and handles — your fitter shouldn't need to source anything else.
Can I have a traffic door in a bi-fold?
Yes. A lead traffic door lets you use one panel like a normal door for everyday access, without folding back the whole run — the most popular option on 3-panel and larger sets.
Aluminium or uPVC bi-folds — which should I buy?
Aluminium, in almost every case. It carries bigger glass on slimmer frames, holds its geometry over time so panels keep running smoothly, and takes any RAL colour. uPVC bi-folds are cheaper upfront but bulkier and more prone to movement.
Who installs supply-only bi-fold doors?
Your own builder, window fitter or joiner. Bi-fold sets are a routine install for any competent glazing trade — and buying supply-only typically saves a significant margin versus a supply-and-fit package.
