Expanded Perlite: Provides good dimensional stability and excellent insulation value with stable R-value. The high perlite content offers far greater fire resistance than conventional wood fiber materials.
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.
FesCant Plus Cant Strips: Manufactured from JM Cant Board, a high-density, laminated perlite board that provides excellent transition from the deck to the wall of the roof.
Tapered FESCO Edge Strips: Excellent for transitioning from membrane to nailer, or transitioning from Tapered FESCO®, Tapered ENRGY 3®, or Tapered Fesco Foam® panels to the roof level to help promote positive drainage.
