Versatile DensDeck® Roof Boards are utilized in a wide variety of roofing systems for new and re-roofing applications as cover boards, overlayments and underlayments. Featuring a combination of fire resistance, strength and dimensional stability, DensDeck roof boards enhance the performance of all roofing assemblies and are widely respected by leading roofing system manufacturers and consultants. DensDeck roof board, with its fiberglass mats, has been shown to withstand delamination, deterioration, warping and job site damage far more effectively than paper-faced gypsum board or other conventional roofing products, such as wood fiberboard and perlite. DensDeck roof boards are resistant to mold growth, and have scored a 10, the highest level of performance for mold resistance under the ASTM D 3273 test method.
