COR Vision Slim Sliding Doors for Sunderland homes and sites
COR Vision is the specification to reach for when an architect has drawn a minimal sightline and a standard patio door won't hold the detail. It's a heavier, more demanding system, so the structural opening and lifting access both need thinking about before you order.
We supply cor vision slim sliding doors across the SR postcode area and the rest of Tyne and Wear, including Gateshead, Whitley Bay and Newcastle upon Tyne. We manufacture and deliver — your own installer or builder does the fitting.

COR Vision Slim Sliding Doors in Sunderland — questions we get asked
What makes COR Vision different from a standard sliding door?
The interlock between panels is much slimmer, so two panels meet in a near-invisible join rather than a visible frame. It's the system used where the glass is meant to read as a single plane.
What does my installer need to plan for with COR Vision?
Lifting and access. The panels are large and heavy, and many installations need glass-handling equipment or a crane, so it's worth your installer planning that before the delivery date is set.
What's the lead time for cor vision slim sliding doors in Sunderland?
4–6 weeks from confirmed sizes — the same wherever you are. Sunderland is about 77 miles due north of our Leeds factory, and every order is delivered on our own fleet, to a fixed date confirmed when you order.
Do you offer trade prices on cor vision slim sliding doors in Sunderland?
Yes. Installers, builders and fabricators across the SR area — Sunderland, Gateshead, Whitley Bay and Newcastle upon Tyne — can open a trade account: manufacturer-direct pricing, no minimum order value and a dedicated account manager.
