Fold It Back. Open It Up.
APX Fold stacks the leaves clear of the opening, so the room and the garden read as one space. Behind slim 122mm sightlines sits an upgraded thermal core, a 30mm polyamide break with foam-insulated profiles, holding U-values from 1.4 W/m²K without thickening the frame. Leaves run up to 1200 x 2500mm, in any RAL colour, with a 10 year guarantee.
Engineered to disappear.
Made in Britain to your exact opening. Thermally-broken aluminium, a folding action that clears the whole span, and four reasons it earns its place at the back of the house.
Folds the wall away
Leaves up to 1200 x 2500mm fold back and stack clear of the opening, turning the back of the house into one room that runs straight out to the garden.
Warmer than it looks
A 30mm polyamide thermal break, over 60% wider than the previous generation, gives U-values from 1.4 W/m²K and an A energy rating with no loss of sightline.
Secure as standard
The standard roller is PAS 24 approved, with shoot bolt locking on the leaves and a heavy duty shoot bolt handle option in place of the standard D handle.
Details that matter day to day
A low threshold option, an integrated cill, optional trickle ventilation and magnetic latches that hold the leaves steady when the wind gusts.

Two rebated outer frame profiles, an integrated cill, or a low threshold for a near level step. A period style sash option matches traditional windows and doors, and hooded trickle vent sections are available in 70mm and 82mm for background ventilation.

How long does installation take?
Most window installs are completed in 1-2 days. Doors typically take 1-3 days depending on threshold work. Full-house or multi-room replacements run 3-7 days. We give you a precise schedule at the survey stage so you can plan around it, no open-ended jobs.
Is the installation FENSA-registered, and do I get the certificate?
Yes. Apex Glazing is FENSA-registered (Reg 40373). On completion you receive a FENSA certificate, which satisfies Building Regulations Part L compliance and removes the need for separate council approval. Certificates are issued within 30 days and stored in your FENSA online account for future house sales.
What warranty do I get?
10-year manufacturer warranty on the product itself (frame, glass seal, hardware) plus a 12-month workmanship guarantee from us on the installation. We've been trading since 2005 with 6,340 completed projects and a 5.0-star Google rating, we'll come back if anything's not right.
Do you remove and dispose of the old windows or doors?
Yes, removal of existing units, safe disposal at a licensed waste facility, making good of internal and external reveals, and a thorough final clean-up are all included in the quoted price. There are no extras for skip hire, scaffolding, or waste removal.
Can you match existing windows for a phased replacement?
Yes. We can RAL colour-match the new frames to your existing units, replicate sightlines, glazing bar layouts, and hardware style to keep a phased replacement consistent. Bring photos to the survey, or we'll come and measure the existing windows so the new ones blend in seamlessly when fitted alongside.
