Longlight 5-45° [Wall Mounted]

A rooflight system for commercial and public buildings. The system consists of prefabricated modular skylights, including profiles, panes, flashings, control systems for natural and smoke ventilation and roller blinds.

Perfect for larger rooms and corridors, Wall-mounted Longlights are bands of modular skylights pre-fitted with installation brackets and clamps that guarantee a fast and secure installation. The design of the flashing allows for configurations with pitches between 5° and 40°.


  • Framing material ensures very low U-value.
  • Complete daylight and ventilation control.
  • Superior environmental profile compared to aluminium rooflights.
  • Slim profiles and flush exterior surface provide an elegant appearance.
  • Integrated chain actuator creates an identical look for fixed and venting modules.
  • Internal blinds complete the interior with a 'free-floating' design.


  • ACR(M)001 Class A non-fragile assembly.
  • CE-marked to BS EN 14351-1.
  • Tested and approved in accordance with BS EN 12101-2.
