SilentFiber™ Polyboard is designed to reduce reflections and eliminate flutter echo to provide high quality listening and/or recording environments. Installation is made easy with a double-sided adhesive backing, for a simple Peel-And-Stick installation process. The main benefit of acoustic polyboard is that treated spaces receive more absorption with less material. Polyboard is highly acoustically rated, yet lightweight and easy to install, making any treated space sound better and look better. Polyester acoustic board is one of the most cost-effective methods of acoustic treatment and noise control. Polyboard is precision cut to exact dimensions (Columns: 1″x1’x4′ Squares: 1″x1’x1′). The SilentFiber Polyester Acoustic Room Treatment Kit (8pc.) is for rooms up to 100 sq. ft. Kits can be combined for coverage of larger spaces.
