APPLICATIONS

Bi-Folding Insulated Glazed Doors

PRODUCT DESCRIPTION

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. They can be manually operated, with a hand chain, or through 3ph/1ph motors (depending on size) and seamlessly integrated into existing BMS systems, allowing for remote control, auto-timed closing, and autonomous operation.

TECHNICAL DATA

PRODUCT SPECIFICATIONS

COMMON USE

Warehouses, Loading Bays, Garages, Hangars

DIMENSIONS

The door is available in sizes up to 50,000mm wide x 8000mm high.

FINISH

Various colours are available from the standard range, with the option of other colours for an additional cost. It's worth noting that dark colours may cause temperature differences if exposed to temperatures exceeding 45°C, potentially leading to deformation and damage to the steel sheet separating from the insulation material. Therefore, dark colours are not recommended for doors exposed to high temperatures or prolonged exposure.

OPERATION

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.

APPLICATION

This modern door blends exceptional thermal insulation and sound absorption within its 55mm thick panels. Key features include various steel sheet finishes, glazing and louvre options, and a unique top-rolling design that eliminates the need for a bottom rail. It offers 90 or 180-degree opening angles and optional wicket doors, windows, and electrical operation.

Suitable for medium-sized openings, it's durable with Class 4 wind load resistance. This versatile door operates as a sliding or bifolding unit, requiring just 150mm headroom.

Manual or optional electrical operation is available, and it can reach a maximum height of 10 metres. Surface finish options include smooth, embossed, or stucco steel sheets with glazing and louvre choices. Plus, you can opt for a wicket door for enhanced accessibility.

ARRANGEMENT

The door system can be configured as single bunching or bi-parting sliding doors, either bunching within the structural opening or clearing it.

LOCKING

Locking is achieved via a motor for electric operation. Manual doors can be locked using an internal black cremone 2-point bolt.

ControlS

Control options include a surface-mounted key-switch or digi-pad, radar/induction loop for egress, remote control, and connections to existing Building Management Systems (BMS) with auto-timed closing functionality.

OPTIONS

The door offers various vision options, including fully glazed aluminium profile panels for part or the entire door divider. Additionally, there are options for windows with insulated panels, including double glazing with straight or rounded corners.

SAFETY

The door system incorporates adjustable pins and an anti-derailment device on the track system. Automatic operation includes safety features such as a safety edge and photocells.

PERFORMANCE

The standard 55mm panel offers insulation with a value of U=1.60 W/m2K. It also provides a typical acoustic performance of 22db. The door has a wind resistance classification of Class 4 and features an air/water sealing system using Black EDPM and nylon brush strips between the top track and the top of the panel.

PANELS

The door panels are constructed with 55mm steel sandwich panels filled with high-density PU foam.
