High-density, protective, perlite-based cover board or low-thermal insulation board proven to reduce blistering in hot-asphalt applications.
Meets the requirements of ASTM C 728, Type 2
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 superior 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.
High Density*: Allows for installations directly over a wide flute or metal deck application for spans up to 2½" and resists damage from construction and maintenance.
Hot Asphalt Friendly: Can be used as a cover board in re-roofing and new construction, proven to reduce the tendency for blistering in hot asphalt applications.
