Engineered Wood Construction Guide
APA engineered wood products are used in a wide range 
of construction applications. Time-tested panel products 
are used in traditional wood-frame construction and in 
combination with other engineered wood products and 
systems. For low in-place cost, versatility, and superior 
performance, engineered wood systems are simply hard 
to beat.
This guide from APA is designed as a reference manual 
for both residential and commercial construction. It 
contains up-to-date information on APA Performance 
Rated panels, glulam, I-joists, structural composite 
lumber, specification practices, floor, wall and roof 
systems, diaphragms and shear walls, fire-rated systems 
and methods of finishing.
If what you want to know about engineered wood 
construction systems isn’t fully explained here, chances 
are it is in one of our many other publications. Titles cited 
throughout this publication can be downloaded or ordered 
from the APA website, at www.apawood.org. Or, for 
individual assistance with specific application questions or 
problems, contact the APA Product Support Help Desk at
