COR Vision Slim Sliding Doors for Reading 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 RG postcode area and the rest of Berkshire, including Henley-on-Thames, Bracknell and Marlow. We manufacture and deliver — your own installer or builder does the fitting.

COR Vision Slim Sliding Doors in Reading — 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 Reading?
4–6 weeks from confirmed sizes — the same wherever you are. Reading is about 164 miles due south 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 Reading?
Yes. Installers, builders and fabricators across the RG area — Reading, Henley-on-Thames, Bracknell and Marlow — can open a trade account: manufacturer-direct pricing, no minimum order value and a dedicated account manager.
