Arched skylights

The width of the skylights can be from 1 to 6 m, the length is unlimited, which results from the panel structure of the light strip. The supporting structure of the roof skylights is a system profile made of corrosion-resistant natural aluminum or painted in any color from the RAL palette. The filling of the transom is a multi-chamber polycarbonate board – available in various colors and thicknesses.

Main features of DWD Sky Light Plus skylights:

  • unique design of the base profiles, enabling the creation of coverings from sets of polycarbonate panels
  • clamping profiles (upper) are not drilled during assembly
  • skylights’ faces are prefabricated in the production process



The supporting structure of arched roof skylights is a base made of galvanized steel sheet. Depending on the needs, it is possible to make the base in any color from the RAL palette and adapt its structure to the roofing. Basically, it is required that the base be supported by a load-bearing structure placed around the perimeter of the opening, in exceptional situations it is possible to construct self-supporting bases based only on the load-bearing frames of the building structure.

The solutions used in DWD Sky Light Plus guarantee:

  • easy and quick assembly
  • clamping profiles (upper) are not drilled during assembly
  • durability strength and corrosion resistance
  • low own weight
  • optimal illumination of the object
  • maintaining thermal protection conditions

With the appropriate configuration in terms of the dimensions of the rooflight structure and the materials used for its production, it is possible to achieve the total heat transfer coefficient for the complete skylight with the base at the level of U=1.1 W/m 2 K. This allows for greater comfort of users and reduction of facility operating costs, as well as of pollutants emitted to the atmosphere from thermal energy sources.
