Inquiry (采购产品): sound barrier We've recently installed a material transfer fan to move saw dust into a trailer. It is a little noisy. We are looking to deaden the sound coming from some of the ductwork. We have some 8" and some 10" ducting. Do you have a product that we could wrap around our exterior ducting? Would it weather well? I would also like some sort of a cover over the motor and fan assembly. Any ideas for that? The motor is a medium sized assembly bolted to a concrete slab. All of these components are outside in an area that at times during the year would be covered with snow. Durability would be an issue here.
