[Ready-to-Use 5cm Corrugated Sheets, Set of 4] Soundproofing Fast Lab Extra Thick Corrugated Urethane Foam Sponge, Sound Absorbing Material,

✅ [70% thicker!] In response to customer requests for a thicker sponge, we have added an extra-thick 5cm sponge. It has even better sound absorption and cushioning properties than a 3cm sponge. ✅ [No need to worry about losing its shape] We carefully package the product to prevent it from losing its shape as much as possible. You don't have to worry about opening it and finding that the sponge is deformed and you can't use it right away. ✅ [No need to worry about unpleasant odors] There is almost no unpleasant odor that is common with other products. It is not so smelly that you have to dry it for a day before using it, and it is not impossible to use it indoors, so you can use it immediately from the moment you receive it, regardless of the purpose or location. ✅ [Efficient sound absorption with wavy structure] The wavy surface structure ensures a large sound-absorbing surface area. It is effective against random sound incidence. For sound deadening, stick it to the walls of your car, home theater, piano room, music room, etc. for efficient sound absorption. ✅ [Efficient shock absorption with wavy structure] The unevenness of the wavy structure disperses shock, protecting your valuables. As shock protection for pedal cases, camera cases, attaché cases, and computer storage. As vibration prevention material for aquariums and motorcycle rear boxes. As a dust prevention material for homemade aquarium filters and ventilation holes. Because it is a simple product, it can be used for a variety of purposes. ✅ [About sound absorption and sound insulation] Sound absorption is the absorption of reflected sound. Sound absorption makes the sound clearer. Soft, uneven materials such as sponge are effective, and this product is ideal. Sound insulation blocks sound so that it cannot be transmitted, for example, preventing the sound of a piano or stereo from escaping. It prevents outside sounds from entering. Materials must be hard and heavy, such as soundproofing sheets, plasterboard, or lead. *This product cannot block sound. ✅ [Specifications] Size: 25 x 25 cm, Thickness: 5 cm, Contents: 4 sheets, Material: Urethane foam, Features: Flame retardant, Density: 26/m³ ✅ [Caution] The corrugated sheets are packed on top of each other, so although they appear flat, they have slits and are separated into corrugated sheets.
