TopLoc® Coating: Top surface is sealed with this special coating to reduce excessive asphalt absorption in hot-asphalt applied roofing systems.
Expanded Perlite: Provides good dimensional stability, excellent insulation value with stable R-value and fire resistance.
Reinforcing Cellulosic Fibers: Consists of recycled newsprint to provide strength to the board as well as high recycled content. JM utilizes third party certification by UL environment to certify the recycled content and contributes to the LEED Materials and Resource (MR) credit 4.
Hot Asphalt Friendly: Utility board for use as a divorcing layer in re-roofing and in new construction as a top layer in multi-layer insulation systems proven to reduce the tendency for blistering in hot asphalt applications.
