Reducing sound transmission is a critical component and requirement in the construction of residential and commercial buildings. Sound Block E90 acoustical sealant from DAP is designed to reduce sound transmission and improve STC ratings in sound-rated wall & floor systems.
Sound Block E90 is ideal for sealing openings around electrical boxes, pipes, duct systems, cut-outs and other types of utility equipment penetrating wall surfaces, as well as perimeter edges including abutting surfaces and corner joints. It also reduces smoke migration and drafts. Sound Block E90 meets all of the industry standards required for these applications, such ASTM E90, C919 and E84/UL723, making it the ideal choice for professionals.
Sound Block E90 improves productivity with its gun formula that reduces fatigue, two-hour paintability, multi-material adhesion and non-sagging formula. The sealant also has cold weather performance by remaining flexible to endure expansion and contraction caused by temperature and weather extremes without cracking or losing adhesion.
Sound Block E90 is packaged in a 28 fluid ounce plastic cartridge that holds up to weather, transit and use, unlike fiber cartridges. It also offers water clean-up, low odor, VOC compliance and will not discolor over time.
DAP Sound Block E90 is available for purchase in lumberyards and building material distributors nationwide. Read additional information.
