Why choose our aluminium bi-folding doors?
Create a wide, uninterrupted opening between your home and garden. Our system is a proven, UK-leading aluminium bi-fold design with upgraded thermal barrier technology, integrated cill / low threshold options, and heavy-duty hardware that’s built to last.
Slim sightlines. Colour to suit your home.
You get contemporary slim profiles for maximum glass and daylight. The system supports dual colour (different colour inside vs outside), plus a full range of durable powder coated finishes – from classic black and anthracite through to heritage colours.
We can match other aluminium items on your home, like lantern roofs or windows, for a consistent finish across the whole extension.

Measured, installed & supported by HI Q WINDOWS
We survey every opening, manufacture and supply the correct configuration, then our own fitting team installs and signs it off. You get building regs compliance paperwork, product warranties and a direct line back to us for aftercare – no subcontract chasers, no call centres.
Not sure what will fit?
Send us a quick photo of your opening (inside and outside) plus a rough width × height measurement. We’ll confirm what’s possible and if you’ll need planning, steels or a structural lintel before the doors go in.
We’ll also tell you which threshold type makes sense (integrated cill, rebated, low / flush, etc.) so you don’t end up with a trip lip across your new extension.

Engineered for daily use
Heavy-duty running gear, reinforced rollers and magnetic catches keep panels stable and smooth to operate. It feels solid, not flimsy, and it’s designed to be opened every single day – not just in summer.
Ask about a single ‘traffic door’: one panel that acts like a normal back door for quick in/out without folding the full set.
- Reinforced bottom rollers
- Magnetic panel hold-backs
- Everyday traffic door option
Level finish from inside to outside
We can supply and fit low thresholds and integrated cills that minimise the step, making it easier to walk straight out to the garden and helping create that seamless indoor / outdoor feel people want in modern kitchen extensions.
On survey we’ll look at floor heights, plaster lines and drainage to make sure it not only looks good in photos – it works in real life.
