PRODUCT: MB Technology TU35 30# Layfast SBS Modified Asphalt Fiberglass Mat Reinforced Underlayment / Base Sheet. Mechanically Fastened. 3.31' x 64.75' rolls (2 Square). 33 Rolls/Pallet. Price/Pallet. (shipping leadtime 2-4 days)
DESCRIPTION:
Ideal for use under tile, shingle roofs. Lays flat during application. Higher tensile, tear and weight compared to 30 and 40# felt. The open mesh construction of the asphalt coated fabric allows the surface coatings to penetrate through and interlock, thereby providing a firm mechanical bond between coatings, and insuring long life of the application. This strong elastic interlocking system is very pliable and prevents rupture due to expansion and contraction of the applied surfaces.
APPLICATIONS: SBS modified underlayment for use under tile, shingle roofs. Lays flat during application. Higher tensile, tear and weight compared to 30 and 40# felt.
FEATURES: SBS modified asphalt underlayment/base. Reinforced with fiberglass mat.
