The insulation board withstands higher loads such as snowfall. It shows almost no deformation in the long term. And under the supporting structures of a solar installation, it is also suitable as a wear layer for lightly greened flat roofs or as a substrate under terrace coverings that make it pleasant to spend time on the roof.

Insulation boards are available in thicknesses of 60, 80 and 100 millimetres. They complement any flat roof insulation as a top wear layer with which the desired thermal protection is achieved. Solarrock has a compressive stress of more than 80 kilopascals.
