Spacious and more light

Cruved rooflights

As the name suggests, a curved rooflight has a rounded shape, with the radius of the profiles and plastic panels being made according to the project specifications.

We supply curved rooflights and coverings made from high-quality aluminium or polycarbonate or other plastics, fully tailor-made. Arcolux rooflights are constructed from a proprietary profile system. This system results in a solid construction that enables large self-supporting spans to be achieved. In combination with the chosen materials, this ensures an impact-resistant and strong daylight solution.

The profiles are manufactured from high-quality plain, powder-coated or anodised aluminium. The rooflight can be placed on steel, wooden, plastic or concrete upstands. Our coverings are fully self-supporting but can also be provided with additional structural elements.


The curved rooflights from Arcolux are made from high-quality plastic. The use of plastic makes it possible to realise the desired curved shapes and also ensures that the entire construction, including the aluminium profiles, has a low weight. The plastic is extremely impact-proof, can be made hail-resistant (up to and including HW5) and can offer good insulation values. In addition, the entire construction can be made fire spread resistant to EN 13501-5 and DIN 4102-7.

Glazing options:

  • polycarbonate (PC), solid (single, double or multi-walled)
  • polycarbonate (PC), hollow core panel
  • acrylic (PMMA), solid (single, double or multi-walled)
  • lightproof

For each type of panel, we can provide advice in the areas of colours, insulation values (Energy Performance Compliant /EPC), light and sun irradiance values, sun protection, fire safety, fall protection and soundproofing.

Integrated protection from the sun

The plastic panels can be given an integrated sun and heat-resistant coating. The plastic glazing material used by Arcolux is protected against UV as standard.

Glazing with printing

The plastic panels can be given full-colour foil prints to create a unique rooflight (e.g. with your logo).


Arcolux supplies systems with optimal insulation values according to EN ISO 6946 for both the panels (Ug) and the complete system (Uw), for which the latest insulation technologies are used.

All popular ventilation systems can be used in Arcolux rooflights. From simple, manually operated ventilation vents and grilles to centrally controlled electrical or pneumatic systems for the automatic venting of smoke and heat. See below for an overview of the possibilities. In addition, a ventilation system can also be mounted in a bulkhead.
