More features

• 【Egg-Crate Is the Most Soundproof Design】The Principle of Acoustic Foam is that when sound contacts with the foam, a portion of sound is reflected, while others get inside the foam, where the sound undergoes friction and reacts with the Sound-Absorbing Material, generating heat. Compared to other shapes, the advantage of Egg Crate shape lies in its increased surface area for sound reflection and its intricate network structure that provides better conditions for friction and heat generation.
• 【Fire Resistance & Non-Toxin Safety】Compared to other panels, our Soundproofing Panels are more suitable for indoor usages. Fire rating:We have passed California Technical Bulletin 117-2013. Non-toxin:Our panels are made of polyurethane materials.
• 【1.5 Inches & Easy to DIY】WVOVW found that Acoustic Foam Panels designed to be 1.5 inches thick is the best. The soundproof effect of 1-inch-thick one is not good and the 2-inch-thick one is easy to fall off and makes people feel oppressed.
• 【Package】For eco-friendly shipping, the egg crate foam will be vacuum-sealed. However, there's no need for concern. Simply separate the panels from their interlocking status and allow them to sit in a well-ventilated area. They will soon regain their desired shape. P.S. The included installation manual is a universal version applicable to all designs.
• 【Wider application areas】In addition to its sound-absorbing function, due to the product's high resilience and strong cushioning, it also serves purposes such as packaging filling, gift protection, and pet care.
• 【Customer Service】WVOVW provides a quality guarantee for the product and will offer the most satisfying service for you. When you suffer some problems, just contact us and we will reply at once.
