5540 Resat-Mat

Karnak #5540 Resat-Mat spunlaced fabric is a textile material composed of polyester fibers entangled to form a strong reinforcing fabric with cold roofing mastics and liquid elastomerics. Composed of 100% polyester, Karnak #5540 Resat-Mat has excellent conformability, making it ideal for replacing felts and fiberglass as reinforcing mats on rough roof surfaces, such as transit roofs, metal roofs or gravel surfaces. The distinctive characteristics of Karnak #5540 Resat-Mat include high tensile strength compiled with high elongation, outstanding tear strength and toughness, high bulk and porosity, nonraveling edges, and excellent dimensional stability.
