OWLKELA Sound-Absorbing Panels, 36 Panels, 30x30cm, Extra Thick 5cm, Sound-Absorbing Sponge, Double-Sided Tape Included, Noise Reduction, Musical

[Excellent Sound Absorption] Each pack contains 36 sheets of 30x30cm soundproofing sheets. Made with 25kg/m³ high-density urethane foam and 5cm thick, they effectively reduce noise. Their porous structure converts sound vibrations into thermal energy, effectively absorbing reverberation and everyday sounds. [High-Resilience Material] The soundproofing material features a pyramidal shape, allowing it to quickly return to its original shape even when pressed or bent. It will not deform even after extended use. Its excellent impact resistance makes it suitable for protecting walls and floors. [Flame Retardant and Thermal Insulation] The soundproofing material is made from flame-retardant material that meets fire safety standards. In addition to automatically extinguishing fires away from the source, the porous structure creates an air gap for excellent insulation and heat retention. Keeps you cool in the summer and warm in the winter. [Recommended Use] The soundproofing material arrives compactly compressed. After opening, allow to dry for 24-48 hours or soak in water for 10-15 minutes and allow to air dry. To achieve optimal sound reduction and soundproofing, we recommend that the installation area of the sound-absorbing panels cover at least 70% of the room's walls. [Easy Installation and Versatile Use] The soundproofing sheet comes with strong double-sided tape, so it can be easily installed by simply sticking it to the wall or ceiling. It can be cut freely with scissors, making it ideal for partial soundproofing. It can be widely used for noise reduction in music rooms, home theaters, and rental properties.
