12 Pack Acoustic Foam, 30 x 30 x 2.5 cm Self-Adhesive Acoustic Panel, Sound Insulation, Noise Cancelling Foam for Home, Studio and Office

The self-adhesive acoustic foam is made of high-density polyurethane material with a density of 25kg/m3. It can quickly expand to its maximum thickness (1 in) in a short time, and the material has no pungent odor. our acoustic foam has a flame-retardant property (resists the spreading of flames), but it is not fireproof (does not withstand direct and intense fire). Acoustic panels are designed for sound absorption and sound insulation. The pyramidal surface increases the contact area with sound waves, effectively absorbs environmental sound waves, reduces reflected sound and echoes, improves the acoustic quality of the room, and simultaneously reduces noise. The soundproofing panels have a built-in adhesive layer, so no additional adhesive tape is required. They can be installed directly on different wall surfaces. The panels are securely fixed after installation and can be easily removed without causing significant damage to the walls. Please make sure the wall is flat and free of foreign objects such as powder when you publish. The adhesive acoustic insulation is suitable for recording studios, personal studios, offices, living rooms, live broadcast rooms, private cinemas, or any environment requiring sound quality and noise absorption. It is also suitable for DIY sound absorption boxes. Easy to shape and cut, change will not affect performance. You will receive 12 pieces of acoustic wall insulation with a size of 30 x 30 x 2.5 cm. Products are shipped vacuum-packed. To accelerate the expansion, it is recommended to tumble dry them. If the edges/corners of this pyramid-shaped foam do not recover well, you can soak them in water for 0.5 hours and then heat or air dry them. If some soundproof panels cannot be recovered effectively, please place them in a cool and ventilated place for 12-48 hours.
