COR Vision Slim Sliding Doors for Durham 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 DH postcode area and the rest of County Durham, including Bishop Auckland (9 miles south-south-west), Sunderland (12 miles north-east) and Gateshead (12 miles due north).We manufacture and deliver — your own installer or builder does the fitting.
Durham carries a lot of period and conservation-area stock, so colour and section profile tend to matter more here than raw specification. RAL colours and heritage-style doors are both available — check with the local planning office before you order.

COR Vision Slim Sliding Doors in Durham — 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 Durham?
4–6 weeks from confirmed sizes — the same wherever you are. Durham is about 68 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 Durham?
Yes. Installers, builders and fabricators across the DH area — Durham, Bishop Auckland, Sunderland and Gateshead — can open a trade account: manufacturer-direct pricing, no minimum order value and a dedicated account manager.
