The non-permeable underlay is a material shielding insulation and roof structure from humid and warm air penetration. It constitutes a barrier
for water vapour forming inside the building, protecting at the same time wooden elements of the roof structure and insulation against moisture.
Application of Krontherm and Kronfol VP non-permeable underlays for insulation and protection of the roof brings many advantages:
