Features and Components
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.
Tapered Design: Factory cut taper, that is easy to install and cut, builds slope into an otherwise flat roofing system, allowing water to drain freely off the roof.
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: Perlite board proven to reduce the tendency for blistering in hot asphalt applications.
