Rooflight Accessories

Electrical sun protection

The electrical sun protection can be installed in every alwitra® kerb. The sun protection is mounted directly under the rooflight or the glazing of rigid rooflights. Alternatively, an installation in the roof opening is possible.

  • multi-layer plissé made of white polyester
  • perfect fit of the white-coated aluminium profiles with the profile of the frame or the kerb
  • almost noiseless operation
  • power supply from integrated solar cells; an electrical connection is not required
  • incl. remote control

alwitra® fall-through protection grating

Square and rectangular alwitra® rooflights can be equipped with galvanized white (RAL 9016) fall-through protection grating according to GS-18. Due to the universal installation options

  • underneath the kerb
  • in the kerb
  • in the vent frame directly underneath the rooflight
  • fall-through protection can be ensured in virtually every installation situation - even later

alwitra® fall-through protection gratings are available for all square and rectangular alwitra® rooflights. For the size of the grating please note the place of installation (roof opening size or daylight size).
