Abstract
A system for introducing a noise-dampening polymer in-line in the manufacturing process of a manufactured wood product to achieve higher acoustic performance in siding, sheathing, roofing, flooring, and similar applications using the manufactured wood product. Several lines or bands of the noise-dampening polymer are deposited transversely across one side or face of the product. The polymer is deposited where the product is expected to contact joists or studs. The polymer may be a viscoelastic polymer.
Claims11
A product with acoustic dampening properties, comprising:
- a manufactured wood product with a first edge, a second edge, a front face, and a back face;
- a plurality of pieces of noise-dampening polymer, each piece of noise-dampening polymer affixed in a location on the back face, wherein at least two of the plurality of pieces of noise-dampening polymer are spaced at pre-determined distances from the first edge of the manufactured wood product and each other.
