Aliplast AS-20 Slimline Sliding Doors Features

Start with the published benefits that most affect performance, appearance and day-to-day use.

Minimal framing across large openings

AS-20 uses a narrow central interlock and concealed frame approach to keep attention on the glass and view.

Design the opening around movement

Track count, pocketing, open corners and fixed panels all affect drainage, cleaning, structure and the amount of clear opening.

  • Decide sliding and fixed panels around the required clear opening.
  • Resolve pocket or open-corner layouts with the structure before ordering.
  • Plan safe access for glass cleaning and future maintenance.

Resolve the hidden details

Minimal systems rely on accurate interfaces around structure, thresholds, drainage and finishes. These are checked during design and survey.
  • Set track support and drainage across the full opening width.
  • Coordinate flush finishes without obstructing the drainage path.
  • Check tolerances at pockets, corners and adjoining cladding before manufacture.

Frequently Asked Questions

Clear answers to the practical questions that often shape the final specification.

Do I need a survey before ordering?
Yes. Final sizes, configuration, thresholds, glass, hardware and installation details should be confirmed through a measured survey and written quotation.
Can I choose the frame colour and hardware?
Colour and hardware choices depend on the selected system. We will confirm available finishes, samples, compatibility and any effect on lead time before order.
Can AS-20 create an open corner?
An open-corner configuration is published. It requires project-specific structural, threshold, drainage and installation design.
