What does Exposure 1 rating on the grade stamp mean?

Exposure 1 rating means that the panel uses a waterproof resin. It does not mean the panel is waterproof but rather that the panel will withstand normal delays in construction without affecting the structural properties (strength) of the panel. All Windstorm panels carry the APA, The Engineered Wood Association, grade stamp.
