DuraBoard - Insulation and Cover Boards
Meets the requirements of ASTM C 728, Type 2
Polymerized Asphalt Emulsion Coating: Allows for direct application of SBS or APP membranes using torch application techniques, and does not require pre-heating like heavily coated boards. This allows for fuel savings and labor efficiency by eliminating fasteners with a mechanically fastened base sheet.
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.
High Density: Provides additional strength and durability.
