LBS Liber/Librum Sliding-Folding doors are perfect for high-use, insulated spaces like ambulance depots and fire stations. With impressive U-values and dB ratings, they offer top-notch thermal efficiency and quiet operation, crucial for residential areas.
The sliding-folding design operates without a bottom track, suitable for openings up to 12,000mm x 8,000mm. The Librum variant, with a heavy-duty bottom track, suits larger openings up to 50,000mm x 8,000mm.
These doors feature micro-profile panels with various built-in window options. They can incorporate aluminium profile panels with diverse glazing and infill choices or a frame-only option for metal sheets with laser-cut patterns.
Recently, we supplied 2 Librum doors to a West London studio without panels, providing a separate galvanised sheet with a laser-cut soundwave design.
LBS Liber/Librum Sliding-Folding doors come in various colours on request. Integral wicket doors with versatile ironmongery options are also available.

The door system can be operated manually or electrically, with options for both single-phase and three-phase motor systems depending on size and usage requirements.
The electric operation includes a surface-mounted control panel with push-button control for impulse opening and continuous pressure (DEADMAN) closing. Impulse closing also features low-level obstruction protection to comply with BS EN12453:2001.
