Doors
Open the wall.
Bring the garden in.
Bi-folding and slimline sliding systems from Cortizo and Smart Systems, plus Rehau uPVC French doors — made to measure and fitted by our own team.
Choosing a door
Sliding or folding?
The right system depends on how you want to use the space.
Sliding doors prioritise uninterrupted views and ultra-slim sightlines. Bi-folds are designed to open the majority of the aperture. We'll give you a straight comparison for your exact opening — aluminium and uPVC side by side.
Aluminium & uPVC
Bi-folding doors
Fold away an entire wall of glass. Cortizo systems from 2 to 14 panels.
Cortizo
Cor Vision sliding doors
A 20mm interlock and up to 94% glass for near-invisible framing.
Smart Systems
Visofold 1000 & 6000
Two slimline Smart bifolds — one for scale, one for the slimmest sightline.
Also supplied & fitted
- Cor Vision Plus — Cortizo's large-format slider for panels up to 4,000 × 4,000mm, with motorised operation.
- Cor 4700 sliding doors — a 47mm interlock and 2–6 panel layouts at a sensible price.
- uPVC French doors — classic double doors on Rehau profiles, opening fully to the garden.
Finishes
Any colour. Inside and out.
Aluminium systems can be powder-coated in more than 200 RAL shades, with textured and dual-colour options — one colour outside, another inside. Anthracite grey and jet black remain the most popular for contemporary homes.
