Sliding doors

A quieter way to open the whole rear elevation.

Aluminium sliding doors suit wide garden-facing spans where the priority is light, uninterrupted glass and smooth daily operation.

  • Large panes reduce visual interruption.
  • Thermally broken frames support comfort through the year.
  • S67 and Cor Vision brochures are available for early comparison.

Sliding and folding

Move the glass aside when the room needs it.

Bifold and sliding/folding systems work best when the style is designed around entertaining, garden access and the threshold detail.

  • Panel splits are designed around the room and garden.
  • Low-threshold and drainage decisions are made early.
  • Bifold Plus and ALUNA brochures are available.

Details

Handles, interlocks and thresholds decide how resolved the system feels.

The best aluminium projects are won in the details: the grip of the handle, the meeting stile, the drainage line and the way the track meets the floor.

  • Frame and interlock choices shape the visible sightline.
  • Hardware finish should be settled before quotation.
  • Threshold strategy needs to match floor build-up and drainage.
Aluminium details

The finished feel lives in the close-up decisions.

These details are small on paper, but obvious in daily use.

Handle

Hardware that feels resolved.

Handles are chosen for daily use, security and finish rather than treated as a late accessory.

Interlock

Slim where it matters.

Interlocks and meeting stiles control how light the system looks when the doors are closed.

Threshold

Planned into the floor.

Drainage, track depth and finished floor levels are coordinated before installation.
