<p>The present invention relates to multi-layer integral, composite engineered panel having a durable, smooth outer face on at least one of its major surfaces, which remains substantially smooth despite exposure to wet or humid conditions. In this way, lower cost wood products, such as OSB, can be upgraded by having a smooth outer surface appearance in uses, which in the past have been the domain of lumber-based virgin wood products.</p> |
