YOPIN Soundproofing Sheet, 2mm Thick, Approximately 3.5kgm² Surface Density, Compact Size, Lightweight, Soft, Soundproofing Sheet for Indoor Use,

[2mm Thickness] Soundproofing effectiveness is affected by the surface density of the soundproofing sheet. By increasing the thickness to 2mm and achieving a surface density of 3.5 kg/m², soundproofing effectiveness is doubled compared to standard soundproofing sheets. It offers outstanding soundproofing performance with a sound transmission loss of 23 dB at 1000 Hz. It also eliminates radio interference (wireless LAN and cell phone outages). [Easy Installation] The soundproofing sheet size has been improved to 30 cm x 30 cm, weighing only 0.315 kg per sheet. This convenient soundproofing solution can be easily installed even by non-professionals. It eliminates problems such as large installation areas, difficulty in cutting, and wasteful leftovers due to lack of suitable sizes. [Safe Material] The soundproofing panels are made of soft PVC material, which is eco-friendly and flame-retardant. Furthermore, their high density provides excellent waterproof and moisture-proof properties, ensuring safe use. [Wide range of uses] When used in conjunction with compatible sound-absorbing materials (sold separately), the synergistic effect significantly enhances sound absorption and soundproofing performance. It can be used in a variety of situations, including rooms, audio rooms, studios, home theaters, apartment soundproofing walls, and car deadening.
