When stressed, oriented strand board (OSB) panels tend to fail along the edges and at nail sites, particularly if the panel has gotten wet.  This technology presents a system for waterproofing and reinforcing panel edges.  The reinforced edge improves fastener performance and reduces the edge swell and weakening caused by moisture exposure.  Reinforced edges strengthen the panel by up to 20%.
