Systems

Built around large, slim openings.

One material done well: thermally broken aluminium. Lift & slide is our flagship, and every system shares the same finishes and hardware, so a whole house can match.

Flagship

Lift & slide doors

Panels to 400 kg · interlock from c. 50 mm · flush threshold Indicative

For wide garden elevations and big glass. The panel lifts onto rollers to slide, then lowers onto compressed gaskets to seal. Comes with a sizing tool, configurations and full performance data.

Lift & slide doors

Sliding, bi-fold, hinged doors and windows

Same finishes, same hardware family

Slim inline sliders, bi-folds, French and entrance doors, casement and tilt-turn windows, and steel-look screens. Each system page will be published with its certified data.

All systems

Why us

The problems we set out to remove.

Ask architects and contractors what goes wrong with glazing packages and you hear the same complaints. We built the company around fixing them.

“The data was ‘on request’”

Published, not promised

U-values, panel limits, security and weather classes are on each system page, with the certified figure for your sizes at Stage 4.

“They swapped the system”

No silent substitutions

What you specify is what we install. Any change comes to you in writing with its effect on performance first. That's change control you can put in the golden thread.

“Nobody owned the detail”

One team, drawing to handover

Our project manager owns the interface details, the survey, the delivery plan and the installation. We don't subcontract the fitting.

“The lead time moved”

A programme you can build to

Lead times run from signed drawings and are agreed in writing. If our programme slips, you hear it from us first, with a new date.

“I had to phone for every update”

A live project portal

Every project has its own page: the current stage, who has the ball, the promised date, documents, approvals and one message thread. How it works.

Founding projects

We're new. Here's how we make that safe for you.

We don't have a portfolio yet, so we won't show you stock photos and call them projects. We'll show you things you can check instead.

  • Certified system data and test references before you order.
  • A full-size corner sample in your chosen finish, in your studio.
  • Written change control and our own installation team.
  • Payments staged against delivery, with a guarantee from a UK company.
