The Original Engineered Wood Product


Plywood in nonresidential constructionPlywood Basics

Plywood has been one of the most recognized and trusted wood building products for decades. Manufactured from thin sheets of cross-laminated veneer and bonded under heat and pressure with strong adhesives, plywood panels have superior dimensional stability and an excellent strength-to-weight ratio and are highly resistant to impacts, chemicals, and changes in environmental temperature and humidity. Plywood manufactured by APA member mills is available in a wide variety of appearance grades, ranging from smooth, natural surfaces suitable for finish work to more economical grades used for sheathing. With more than a dozen common thicknesses and over twenty different grades, plywood is well-suited to a multitude of demanding applications.
