Proven solutions for exposed roofs

Protan exposed roofing systems combine proven durability with the flexibility to meet different building requirements, roof designs and installation methods. Developed for demanding Nordic conditions, our roofing membranes provide reliable, long-term protection with minimal maintenance.

With over 50 years of experience in roofing membranes, Protan delivers documented solutions for both new build and refurbishment projects. Our systems can be installed on a wide range of substrates and adapted to different roof designs, from large industrial buildings to more complex architectural roofs.

Protan PVC roofing membranes are lightweight, quick to install and joined using hot-air welding to create strong, watertight seams. The membranes are recyclable and can be collected and returned through our recycling solutions, helping to keep valuable materials in circulation.

For exposed roofs, Protan offers roofing solutions in both PVC and bitumen, making it possible to select the right solution based on the building, roof design and project requirements.

Product summary

  • The products are fastened mechanically, by means of a vacuum or with adhesives to the roof construction.
  • The roofing is well suited for both flat and sloped roofs, and for new builds as well as refurbishment projects.
  • Protan’s roofing and membrane products are reinforced according to use and coated with PVC-P (plasticized).
  • The roof coverings have an embossed textured surface providing friction, making them safer during installation and maintenance.
