Epilay Plasfelt Synthetic Underlayment. Epilay® Plasfelt™ Roofing Underlayment with its advanced engineering is highly recommended for mechanically attached, coated woven synthetic roofing underlayment for sloped roofs. Epilay® Plasfelt™ is specifically manufactured to replace the #15 felt and #30 felt.

Epilay® Plasfelt™ is 25 times stronger than 15# felt and 5x lighter than 15# felt. With a 6.5 mil thickness, a 10 square roll weighs only 21lbs! This super low weight combined with 48″ width and 250 ft. run length means big savings in time and labor – over 30% faster to install than felt!

These unique design features, when coupled with Epilay® Plasfelt™ exceptional light weight and exceptional tear strength, allows the contractor to easily carry the roll up and down the ladder. Fewer laps, cuts, and roll handling means you can do more jobs in less time resulting in huge savings for you, the roofing contractor.
