Technical Info


FelTex is a high-strength, lightweight woven fabric used as an underlayment for both commercial and residential roofing. Engineered fabric construction contributes to superior strength and durability.


  • Stronger than Type 30 Felt
    FelTex far exceeds ICC&ASTM requirements for felt and can be left exposed to high winds without ripping away from fasteners or tearing.
  • Lighter than Type 30 felt
    Lightweight rolls are easier and faster to install and transport to the rooftop.
  • Contains no asphalt
    FelTex is 100% inorganic and contributes to a more weather-resistant roof system.
  • 5 times more coverage per roll than Type 30 felt
    A 32 lb. roll covers 10 squares; ultra-light-weight rolls means faster and easier installation.
  • Engineered design improves surface grip and clings to the roof deck
    NO-SLIP skid resistant coating and textured woven surface features contribute to a safer walking surface.
  • Longer UV resistance
    FelTex can be left uncovered and exposed to the elements for 6 months.
  • Will not warp, wrinkle or crack
    Superior lay-flat properties and no water absorption keeps FelTex from warping, wrinkling and cracking in cold weather.
  • 30 year limited warranty
    Add value and security to roofing projects and improve the performance of any roofing material.
