By increasing the thickness to 2mm and reaching a surface density of 3.5 kg/㎡, the soundproofing effect is doubled compared to general soundproofing sheets. It has outstanding sound insulation performance with an acoustic transmission loss of 23dB at a frequency of 1000Hz. Also, there is no radio wave interference (such as disruption of wireless LAN or mobile phones). ✅ Easy to install The soundproofing sheet size has been improved to 30cm x 30cm, and each sheet weighs only 0.315kg. It is a convenient soundproofing measure that can be easily installed even by non-professionals. It solves problems such as "difficult to install because of the large area, cannot cut well, and it's a waste if there's extra material because the size isn't right." ✅ Safe materials The soundproof panels use soft PVC material, which is eco-friendly and flame-retardant. In addition, it is waterproof and moisture-resistant due to its high density, so you can use it with peace of mind. ✅ Wide range of uses When used in combination with compatible sound-absorbing materials (sold separately by our company), a synergistic effect can significantly improve sound absorption and soundproofing performance. It can be used in various situations such as rooms, audio rooms, studios, home theaters, soundproof walls in apartments, and car deadening. ✅ Note: You may notice a rubbery smell when you first start using it. The smell will be reduced if you leave the product in a well-ventilated place for about a week. You will need to prepare a separate tacker for installation. $$3980
