48 Pack Self-Adhesive Sound Proof Foam Panels — Fast-Expanding, Fire-Resistant High-Density Sound Deadening Acoustic Panels

Made from high-density polyurethane sponge material, these fast-expanding panels are fire-resistant and highly resilient, recovering within 5 seconds after compression. They are engineered to absorb and reduce unwanted noise, effectively eliminating echoes, standing waves and chattering for improved room acoustics. The self-adhesive acoustic foam design makes them simple to position; panels are easy to cut, easy to use and easy to install.
