Permo forte SK²  


Permo® forte is an extremely strong 4-layer vapour permeable underlay with a built-in safety grid. It is suitable for all pitched roofs. Permo® forte should be laid in accordance with our installation details and BBA/IAB Certificates.

Permo® forte SK² has a double integral tape at the laps. This creates a very effective and secure airtight seal, reducing energy loss.
