1. [Ultra Fast Expand] - Most Bietrun soundproofing foam panels can expand in 1-second thanks to the advanced compression technology and itself composed of 100% ultra-high resilience PU sponge polymer material, and the rest can expand in 6 hours. No more waiting 2-3 days in the washing machine.
2. [Professional Effectively Reduce Noise] - This Bietrun acoustic foam uses 28kg/m³ high-density polyethylene foam material, rather than others are only 20kg/m³ , and uses pyramid-shaped foam to provide reasonable sound control by reducing waves, reverberation, and vibrating echo in studios and offices. The most significant difference from ordinary sound-absorbing foam is the 3D acoustic design, allowing you to enjoy a quieter environment.
3. [Easy to Install] - We recommend using glue, nail, or thumbtacks to install（Not in the package). The sound-absorbing board is compressed in a vacuum package, placed in a well-ventilated place for about 1 minute to 6 hours(max), and can be used after returning to its normal size. Or soak the foam in water for one minute, then wring out the water, use a hair dryer or air dry. Sooner can you practice any instrument, watch movies, play games, or listen to music without disturbing anyone.
4. [Safety & DIY Shape] - Our acoustic foam panels are made of flame-retardant environmentally friendly polyurethane high-density materials, which are safe for adults, children and pets. Cutting dimensions or changes will not affect performance. You can also easily cut and shape any shape you want without worrying about affecting its performance.
