Thermalight Walk On Rooflight

Thermalight Walk-On

The Thermalight Walk-On rooflight is ideal for roof terraces where the space below needs access to natural light. The units have the same characteristics, and deliver the same high quality performance as the standard Thermalight rooflights.

The Thermalight Walk-On rooflight is a low profile system, designed to be flush with surrounding flooring – first fit the rooflight to your existing or new timber builders kerb/upstand, then the surrounding flooring can be raised level to ensure a flush finish with the glazing.


Walk-On rooflights are typically used on roof terraces with decking bringing the benefits of light to the room below whilst providing a real wow factor to any roof terrace.

Ideal for all residential applications, the units meet the imposed load requirements of BS EN 1991 subcategories A1, A2, A3 and A5, i.e. capable of withstanding a uniform distributed load (UDL) of 2.5KN/m2 and a concentrated load of 2.0KN.

The extruded aluminium framework is supplied powder coated to RAL9005 Black Matt or RAL7016 Grey as standard. Other RAL colour options are available upon request.

Avante Garde or Sandblasted anti-slip external glass treatments to BS7976-2 are available upon request for rooflights that may be subject to regular pedestrian traffic.
