COR Vision Slim Sliding Doors for Harpenden 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 AL postcode area and the rest of Hertfordshire, including St Albans (5 miles due south), Luton (5 miles north-north-west) and Stevenage (9 miles north-east).We manufacture and deliver — your own installer or builder does the fitting.

COR Vision Slim Sliding Doors in Harpenden — 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 Harpenden?
4–6 weeks from confirmed sizes — the same wherever you are. Harpenden is about 146 miles south-south-east 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 Harpenden?
Yes. Installers, builders and fabricators across the AL area — Harpenden, St Albans, Luton and Stevenage — can open a trade account: manufacturer-direct pricing, no minimum order value and a dedicated account manager.
