Catwalk™

Catwalk 30 is a high strength synthetic roofing underlayment that provides outstanding protection against water intrusion and outperforms #30 roofing felt in virtually every dimension.

Engineered from a high strength polypropylene fabric and coated on both sides with surface enhanced polymeric coatings, Catwalk 30 provides exceptional strength and tear resistance, so it's equipped to withstand the worst jobsite conditions. Yet, at 33 lbs. per 10 square roll, it's much lighter than roofing felt - so it can be handled and installed easily. The product's reflective surface reduces heat absorption, making it cooler for installers and the textured coating makes their job safer.
