Compared to other materials, the sponge has a high density and sound insulation effect. The soundproof panel is 5cm thick, 25kg/square meter, with a high-density and very thick sponge. It is thick and has high resilience, resulting in a high sound insulation effect. Enjoy high-quality sound in a quieter and more comfortable environment. 【B1 Level Flame Retardancy and Insulation】The sound-absorbing material is officially certified as a B1 level flame-retardant material and will automatically extinguish when away from the fire source. The acoustic panels do not contain formaldehyde and are environmentally friendly and safe. The soundproofing material is impact-resistant and ideal for use as insulation. The soundproof pads utilize the human body's insulation properties to effectively block external heat, providing heat retention and insulation effects. Saves on air conditioning power. 【Sound Absorption Effect】To achieve a sound insulation effect, it is recommended to cover more than 70% of the walls of the room. If you want to improve the sound quality of a part of the room, simply install the microphone on a separate shield or a nearby wall. ===================== * Immediate purchase welcome, silent purchase at midnight OK ◎ * First come, first served for only one item * Bulk purchases welcome, please feel free to comment * Free shipping! * Please contact us before evaluation if there are any problems.ᐟ.ᐟ ・Please understand that the items are stored at home and will be shipped in simple packaging. ・Please check the actual photos for the condition of the product♪ ※In order to sell at a slightly lower price, we may ship the item after taking it out of the box due to shipping costs. #Riyan's product list is here ☜ S42041500
