Description
White uPVC Patio Door – 4 Pane Sliding Design
White at full four-panel width is the safest, most dependable choice in the range — two sliding centre doors, two fixed side panels, and a colour that works with literally any exterior.
White remains our most specified finish for a simple reason: it doesn't compete with anything. Old brick, new render, painted stone — none of it clashes with a white frame.
Living With It Day to Day
Both centre panels operate independently on their own track; the two outer panels are fixed, adding scale without adding complexity.
The Numbers Behind the Comfort
One continuous 70mm thermally broken frame runs the full four-panel width, with Low-E glazing and argon fill maintaining a consistent u-value throughout.
Locked Down Properly
Multipoint locking and anti-lift protection secure the sliding panels; the fixed panels are internally glazed with no opening mechanism to attack.
Built to Fit, Not Fitted to a Standard
Built around your specific opening — at four panels wide, that's the only way this reliably fits.
