wood-based composites as siding materials. the performance of façades designed with wood-based panels and wood-plastic composites over long-term exposure to natural weathering is being investigated and evaluated. completely new approaches are being developed along with possible ways of optimisation.
the north american composite panel industry is predicated on the optimal use of forestry byproducts and residuals — turning this recycled and reclaimed material into higher value products so it's not wasted. by their very nature, composite wood panels—along with agrifiber-based panels—are among the greenest products.
