Summary of PS 1-83 for External vs. Exposure 1 (CDX) rated plywood.
Exterior panels use Type 1 wood, usually Douglas Fir, and a waterproof bond designed for permanent exposure to the weather.
Exposure 1 plywood, commonly called CDX, uses Type 2 or lower grade wood, is not intended for permanent exposure to the weather but uses the same waterproof glues used in External plywood.
As a result, Exposure 1 plywood is often mistaken for Exterior plywood.
Therefore, only APA Exterior rated plywood should be used in applications where it will be permanently exposed to the weather, such as in boats.
Feel free to buy either or both lots priced as marked.
