[Easy Installation] - To solve the problem of difficult installation, we have upgraded our soundproofing sheets with strong adhesive backing. Simply peel off the craft paper on the back of the soundproofing panels and attach them to your desired location. The self-adhesive design means you don't need to prepare extra tape; just ensure the installation area is clean and dry. *Note: Immediately after opening the product, you may notice a slight odor due to the material's properties. If the odor is bothersome, please leave the product in a well-ventilated area for about 24 hours.
[Improved Soundproofing] - To increase the contact area with sound, these sound-absorbing materials are specially designed in an egg shape, naturally enhancing their ability to control echoes, reverberation, and ambient noise. This soundproofing material offers the best solution for customers as part of an overall approach to managing and reducing unwanted acoustic issues.
[Product Specifications] - Each pack of soundproofing mats measures 30 x 30 x 3cm. Each pack contains 36 sound-absorbing foam pieces, each 3cm thick. The high-density soundproofing sheets, at 25kg/m3, are dense enough to absorb mid to high-frequency sounds. Our soundproofing materials are made from harmless urethane sponge, meaning these sound-absorbing sponges are absolutely safe and will not harm your health.
[Fast Expansion] - With stronger elasticity, our black soundproofing panels expand quickly. They typically return to their original shape and size within 24 to 48 hours. Simply place the soundproofing panels in a well-ventilated area, and they will expand naturally.
