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 method of producing a wood product with acoustic dampening properties, comprising the steps of:
- applying a noise-dampening polymer to a plurality of locations on a back face of a manufactured wood product;
- wherein the plurality of locations comprise a plurality of linear areas parallel to each other and a first edge of the product;
- and
- further wherein the plurality of linear areas are spaced at a series of pre-determined distances from the first edge and each other, said spacing selected to correspond to an end-use application with a particular spacing of joists, studs, or other flooring or framing support elements.
