Customized Water Resistant Self Adhesive Sound Deadening Use Butyl + Al Foil + Foam
Product Description:
WanTai is built to the highest standards in this industry using 100% butyl rubber with a layer of heat resistant aluminum. Butyl rubber is the same material high end speakers surround material is made out of. We use the highest quality pressure-sensitive self-adhesive to make your installation quick and easy. Our model has increased flexibility for an easier and more permanent installation! Our sound dampening product uses 4mil of pure grade aluminum! Most products on the market use 2mil. Our product will absorb sound better than the competition. If a product does not specify how much material is being used, you should be very cautious about it! Every manufacturer should know what they put into their products! Also, other products on the market such as WanTai for example use a mixture of asphalt in their products. They basically are manufacturing roofing material and calling it sound deadener. Their product will work OK, but not nearly as good as our China. WanTai is made of butyl rubber and aluminum which is the same as many of the more expensive brands out there that sell for twice our price.. We do not cheat our customers. We only make top quality product
