Permafab is 100% stitchbonded, polyester fabric that offers an unusual combination of high strength properties with good elongation for excellent resistance against thermal stress.

Permafab is used in conjunction with the Solargard and Geogard coatings as a maintenance overlayment for smooth surfaces, embedded gravel surfaces, and single ply roofs.  It is also used in conjunction with Solargard and Geogard Seam Sealers for flashing, seam, penetration, and other detail repairs.
