Discover the ease and performance of Epilay Plasfelt Synthetic Roofing Underlayment, an advanced solution specifically manufactured to replace traditional #15 and #30 organic felts. This mechanically attached, coated woven synthetic underlayment sets itself apart with its remarkably low weight; at a mere 6.5 MIL thickness, a 10-square roll weighs in at only 21 lbs. This makes handling, transporting, and installing Plasfelt significantly easier and faster than traditional felt, contributing to over 30% faster installation times. Despite being incredibly lightweight (5x lighter than #15 felt), Epilay Plasfelt is engineered for exceptional strength, boasting 25 times the tear resistance of #15 felt, which helps prevent punctures and tears during the installation process.

The synthetic construction provides inherent water resistance and durability. While specific named surface technologies like GripWalk or Skid-Resist were not detailed for Plasfelt, synthetic underlayments of this type typically offer good foot traction and some level of anti-skid properties for safer workability on sloped roofs. The generous 48″ width and 250 ft roll length mean fewer laps are needed on the roof, further accelerating installation and reducing potential leak points. Epilay Plasfelt is a dependable choice for use under both asphalt shingles and metal roofing systems, offering a strong, lightweight, and efficient underlayment solution backed by a 20-year limited warranty.
