We manufacture one sliding door system. The Cortizo Cor Vision.
We chose it because we love it.
The Cor Vision is a thermally broken, minimal-frame slider with a true 20mm sightline between panels. Timeless yet modern. Technically flawless.The profile architects return to when they want the frame to disappear and the view to take over.
We don't try to please everyone. We serve people who recognise beautiful quality when they see it, and who value the difference between something assembled remotely and something crafted locally by a team who will also install it and stand behind it.
We fell for this profile. The proportions. The engineering. The way it makes a room feel when the light pours through.
So we committed. One system. Complete focus. We learned every detail, refined how we manufacture it, and built a workshop around doing this one thing exceptionally well.
We know it inside out. We answer questions without checking manuals. We spot problems before they happen. And we tell you honestly whether Cor Vision is right for your project, because we've got nothing else to push.
Commitment looks like this: Cortizo profiles on our racks in Dorset, ready to cut. Black and anthracite grey, the colours that matter, always in stock. No six-week wait for an order from Spain. No crossed fingers at customs.
Our glass partner is fifteen miles from Heathrow. We've worked together for eight years. They know what we expect. When we need something fast, they move. When quality matters, and it always matters, they deliver.
This is why we quote three to four weeks when others quote ten.
Don't cut corners. Remove the waiting.
The aluminium interlock between panels is genuinely minimal - not a modified traditional slider with a slim central bar and thick everything else. The whole frame is designed to disappear.
The outer frame can be plastered into the reveal on all four sides. What you see is glass meeting wall, with no visible frame around the opening. It's the detail that makes rooms feel borderless.
Our interlock profiles sit flush with the glass rather than protruding into the room.
Most competitors' systems stick out. Ours don't. It's a small thing that makes a visible difference.
"The doors arrived exactly when promised, slid like silk from day one, and three winters later they still feel like the best decision we made on the whole build."
"I'd been burned before by glazing companies who overpromised - Kevin's team measured twice, explained everything clearly, and the result is genuinely stunning."
"Our architect specified Cor Vision and we're so glad she did; the frames practically vanish and the room feels twice the size it did with our old patio doors."
Cor Vision works beautifully on ground-floor extensions, new builds, and refurbishments where you want maximum glass and minimum frame. It handles coastal environments with marine-grade powder coating as standard.
For very exposed upper-floor locations with significant wind load, or where triple glazing is essential for thermal reasons, a heavier system may be more appropriate. We are happy to talk through your situation and give you an honest view.
