Soundown - Composite Soundproof Mat

Powerful soundproofing material used in yacht engine rooms and similar areas.

A 3mm thick high-density PVC [Tuff-Mass] (soundproof sheet) is sandwiched between fire-resistant foam (sound-absorbing foam) and covered with an aluminum-coated Mylar film on the surface. It demonstrates excellent effectiveness in blocking and soundproofing engine noise and machinery. ● Compared to many "single-layer soundproof materials" that are only effective for high-frequency sounds, it has outstanding attenuation effects for mid to low-frequency noise from engines, generators, and pumps. ● The surface Mylar film is reinforced with thread, so it won't tear even with rough handling. ● It can be cut with a cutter or scissors, and the back has a strong adhesive seal, making installation easy. ● Soundproofing TIPS * Sound travels through the air. It can easily infiltrate through any gaps, just like drafts. The key to soundproofing is to apply it as tightly as possible to avoid creating "gaps." * When using it for soundproofing a piano room, simply placing it under the instrument will not provide soundproofing effects. It is necessary to "cover" the entire floor of the room. Additionally, placing heavy items like pianos directly on it will compress the urethane. Always install it under the floorboards.
