Regupol® resist solar AK
Product Details
Burning protection underneath Solar Modules
With this product, Regupol® resist solar AK offers a selection of protective layers that has been specifically developed for the installation of photovoltaic systems on flat roofs. The protective layers are marked by their extremely long product life as well as their high mechanical load-bearing capacity. A large selection of product alternatives allows users to find the fitting protective layer for the different types of flat roofs and solar plants.

Regupol® resist solar AK ensures that solar systems are solidly positioned due to high coefficients of friction while at the same time protecting the roof membrane against damage.
Regupol® resist solar AK is available in standard sizes or is “custom cut” to the individual construction.
Regupol® resist solar AK is available in different varieties:
Lamination with a triplex aluminium foil on the underside
This prevents plasticiser migration between non-rubber-compatible roof membranes (e.g. soft PVC) and the protective layer. Protected by German utility model (issued by the German Patent and Trade Mark Office).
Flame-retardant finish
This alternative is considered “hard roofing” as it protects the roof against flying sparks, radiant heat
and fireworks.
Self-adhesive finish
An adhesive layer serves as a mounting aid to secure the protective layer at the footprints and attach
Regupol® resist solar AK to the solar system even prior to its installation on the roof.
These finishes may be combined with one another, which makes for a broad range of product varieties.
