Related to OSB: "Recently we¡¯ve heard that walls in many Southeastern homes covered with the Exterior Finish and Insulation System (EIFS) were rotting. Rigid foam insulation was applied over OSB and coated with a stucco-like covering. When the exterior foam boards were removed, wet, rotted, crumbling osb was exposed. Osb was slammed in the press. The problem really isn¡¯t osb¡¯s fault. All cases I¡¯m familiar with were caused by improper installation of flashing or protective coverings" -- Fisette, 1997, Choosing between oriented strandboard and plywood
