You know hailstorms can cause catastrophic—and costly—damage to commercial roofing systems. DensDeck® Prime Roof Boards help protect membranes better than high-density polyisocyanurate (HD ISO) boards in two ways:
DensDeck Prime performs better in FM 4473 hail tests*, showing less membrane indentation AND the ability to withstand larger hail sizes, while HD ISO boards dent and fracture under the pressure.
DensDeck Prime provides a front-line defense against water intrusion, making membranes 83% more puncture-resistant than those covered by HD ISO boards or nothing at all.
Protect your clients' roofs by specifying the original fiberglass mat gypsum cover board—DensDeck Prime Roof Boards.
*Hail testing (or impact resistance testing of rigid roofing materials by impacting with freezer ice balls) conducted by Jim Koontz & Associates in 2014 in its Hobbs, NM laboratory, according to FM 4473 (using NBS 23 standards.)
