LINECY Soundproofing Sheet for Walls and Rentals, Sound-Absorbing Material, 30x30x0.9cm, Double-Sided Tape Included, High Density 230kgm³,

[Improved Sound Absorption and Excellent Heat Insulation] LINECY soundproofing sheet is made of 9mm thick polyester fiber with a strength of approximately 230kg/m³, providing both sound absorption and heat insulation. It boasts a high sound absorption rate across both high and low frequencies, providing approximately three times the performance of regular soundproofing sheets. It prevents temperature rises on hot days and blocks cold air on cold days. The air layer prevents moisture from accumulating, preventing dampness and mold growth even when used on floors or walls. ✨[Easy to apply and beautiful finish] LINECY soundproofing sheets come with 3M double-sided tape, which provides stronger adhesion than standard double-sided tape. After assembling the sheets to your desired color and shape, simply apply the double-sided tape to the back of the soundproof wall panel at the four corners and in the center. Alternatively, you can easily DIY using pins, hot melt adhesive, masking tape, etc. Note: Please be careful as removing pins or other adhesives may damage the wall surface. ✂[Freely Cuttable and Customizable] LINECY sound-absorbing material can be easily cut with scissors or a utility knife, allowing you to customize it for various areas of your room, such as walls, pillars, and floors. The square design and beveled edges combine decorative wall accents with sound-blocking properties, protecting your family from bumps and scratches. *For optimal sound absorption, we recommend covering at least 70% of the wall with sound-absorbing material. [Safe and Secure for a Wide Range of Uses] LINECY soundproofing sheets are made with high-quality, non-toxic, odorless materials, making them suitable for a wide range of uses. They are ideal for quieting offices and improving audio recording quality, as well as professional studios, rehearsal rooms, concert halls, podcasting venues, churches, home theaters, vocal booths, and home studios. They are also safe for use in homes with small children.
