Description
Grey uPVC Patio Door – 4 Pane Sliding Design
Grey at full four-panel width gives you scale without the visual weight of a darker colour — two sliding centre doors, two fixed side panels, and a finish that suits almost any brick or render behind it.
Grey has settled in as one of the steadiest performers we offer — not as stark as Black, not as soft as Cream, and it works across a wider range of properties than either extreme.
Living With It Day to Day
Both centre panels slide independently along their own track; the outer two stay fixed, adding scale to the opening without adding anything else to operate.
The Numbers Behind the Comfort
The full four-panel width shares one continuous 70mm thermally broken frame, so performance doesn't taper off toward the fixed sections at either end.
Locked Down Properly
Multipoint locking and anti-lift protection cover the sliding panels; the fixed panels are internally glazed with nothing external to force.
Built to Fit, Not Fitted to a Standard
Built entirely around your opening's dimensions — at this width, there's no standard size that would reliably work.
