The Plenum Blanket is a cost-effective and time-saving alternative to building full-height non-rated walls. Perfect for spaces with mechanical ducts or other obstructions, this plenum blanket is easily cut and installed to the above deck or roof and top of drop ceiling walls, stopping sound from traveling through overhead spaces into adjacent rooms. Designed for superior soundproofing, the Plenum Blanket significantly reduces sound transmission between adjacent offices, rooms, and overhead spaces. With added benefits of plenum insulation and versatility, this blanket ensures long term performance and convenience in one reliable solution.
