New Color Available in May 2025 Set of 24 Gray Sheets [35kgm³ Ultra-High Density, Instant Recovery] No Soaking Required. Extra Thick Sound-Absorbing

Our sound-absorbing material is compressed and packaged, but because it is made of a high-density material (35kg/m³), there is no need to soak it in water or wait for it to recover. It is very convenient because it recovers to its original shape immediately after opening. High density and outstanding sound absorption performance. Our sound-absorbing material is 5cm thicker than conventional sound-absorbing panels. The sound-absorbing panels are made with a precisely optimized polyurethane material and feature a high-density, extra-thick sponge of 35kg/m³. The interior of the sound-absorbing material has a porous structure, allowing the soundproofing sheet to convert sound vibrations into heat energy, thereby attenuating the sound. Our sound-absorbing material is effective in noise control, further enhancing the soundproofing effect of the sound-absorbing sheet. Excellent Material & Good Resilience Our sound-absorbing material uses polyurethane foam, which has excellent resilience and durability. It quickly returns to its original shape even after folding, so there is no need to worry about deformation even after long-term use. The sound-absorbing material has a porous structure and high cushioning properties, so it can protect people and objects from collisions. B1 Class Flame Retardant & Thermal Insulation Our sound-absorbing material is made from certified B1 Class flame-retardant material, which makes it difficult for fire to spread and automatically extinguishes when it comes into contact with fire. It also contains no formaldehyde, making it environmentally friendly and safe to use. Our soundproofing sheets utilize the insulating properties of gas to effectively block heat from outside and maintain room temperature. Our soundproofing material is also impact resistant, making it ideal for insulation. Easy to install & versatile Our sound-absorbing material can be easily cut with scissors or a cutter. Once cut to fit the installation area, it can be attached using the included strong double-sided adhesive tape. The wider the installation area, the better the sound insulation effect. If partial sound insulation is required, simply install it near the sound source. ❤️We offer a 180-day warranty, so if you experience any issues with the product or the included double-sided tape, please contact us and we will respond promptly.
