The process of making OSB entails layering wood strands that are typically three to 4 inches lengthy. These strands are blended by using a watertight resin and afterwards oriented in layers to produce a panel which has uniform power throughout all directions. The levels are pressed beneath high tension and heat to variety a reliable, strong board.

Substantial Sizes: The scale of a plywood panel will be inherently minimal by the size of the tree, as Each and every veneer will should be Slice entire.
Toughness: OSB is taken into account a little stronger in shear strength, even though plywood has improved resistance to humidity and warping.
