The Sunstract® combines controllable natural ventilation with the ability to provide natural daylight, meaning the product can contribute to the reduction of energy demand in commercial buildings.

  • Combines natural ventilation and natural daylighting functions in one unit.

  • Provides controllable ventilation with high lumen output.

  • 885mm square ducted system for greater structural stability and light output.

  • Structural sub-base provided for ease of installation and weathering into a wide range of roof coverings.

  • Diffused glazing reduces 'hot spots' and spreads the light for ducting down the system.

  • Reduces the need for artificial lighting or ventilation, also reducing energy costs.

  • Thermally insulated upstand to minimise energy losses.

  • Triple glazing to minimise heat loss.
