J & S Supply is a committed distributor of Johns Manville DuraBoard Cover Board serving New York, NYC, Brooklyn, Queens, Long Island, Westchester, New Jersey, and Connecticut. DuraBoard is a high-density perlite-based cover board. It is a 4′ x 4′ board and is available in 1/2″, 3/4″ and 1″ thicknesses.
Johns Manville DuraBoard’s Cover Board 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. Additionally, the board’s expanded perlite provides good dimensional stability, excellent insulation value with stable R-value and fire resistance.
Johns Manville DuraBoard Cover Board 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.
