Abstract
An engineered wood based siding, cladding or panel with a microstrand interface layer (MIL) applied to the top of the main strand matrix layers to minimize telegraphing, add rigidity and strength, and provide an improved surface appearance. The MIL comprises microstrands applied to the surface of the strand matrix or mat during production, prior to deposition of a fines layer. The MIL prevents the loss of fines into the strand matrix, and helps prevent or eliminate strand telegraphing.
Claims15
An engineered wood product, comprising:
- a multi-layer strand matrix, said strand matrix comprising a top surface with strands of an average first length and an average first width;
- a microstrand interface layer on the top surface of the strand matrix, said microstrand interface layer comprising microstrands with an average second length and an average second width, wherein the average second length is less than the average first length, said microstrand interface layer further comprising an upper surface opposite the strand matrix;
- a fines layer on the upper surface of the microstrand interface layer;
- wherein the strand matrix, microstrand interface layer, and fines layer are consolidated and bonded together to form an integrated engineered wood product.
