Flat Roof Access Hatch Swing

Application

Suitable for residential and commercial applications.

Description

The Flat Roof Access Swing, is a space saving, swift opening exit hatch which opens by 84° in approximately 25 seconds. Available with a choice of 2 lengths – 3000 mm or 3500 mm, the 1000 mm wide exit swing is suitable as a convenient and comfortable horizontally opening roof exit for stairs. The hydraulically opening Roof Exit benefits from enhanced isothermal characteristics in the overall construction – this results in no condensation whilst achieving maximum energy efficiency and thermal insulation alongside excellent air tightness values.


Features and benefits:

  • Thermally broken "isothermally balanced" frame free of thermal bridges combined with triple glazing as standard to save heating costs and minimize condensation.
  • 5° inclination to allow water and dirt to run off naturally.
  • Smooth and fast opening by hydraulic drive creating comfortable and convenient stair (by others) access to the roof terrace in approximately 25 seconds.
  • Delivered as fully pre-assembled unit, which can be crane lifted (not by LAMILUX) into position.

Control

Electrically-operated hydraulic unit (230 V or 24 V).

During standard operation, the power unit is supplied with a voltage of 24 V by a power supply unit. The batteries are automatically charged if required. In case of failure of the 230 V line voltage, the power unit is automatically operated with the 24 V voltage of the batteries. The capacity of the batteries is sufficient for approximately 20 openings of the sash. The failure of the line voltage (battery operation) is indicated by a warning light in the limit switch case.
