for homeowners:
for contractors:
Apart from the advantages mentioned above, high quality KRONfol membranes fulfill the following functions:
KRONfol membranes are intended for pitched roofs ≥ 20° under every type of roofing with air circulation along counter-battens.
KRONfol membranes protect roof structures with both habitable and non-habitable loft spaces. In the roofs with lower pitches (12°-19°) KRONfol membranes can be laid only when fulfilling special conditions which have to be taken into consideration in the roof design.
