New Engineered Wood Construction Guide
APA just issued the 2007 Engineered Wood Construction Guide, the major reference manual for using engineered wood products in residential and commercial construction.
The biennial publication provides recommendations for floor, wall, and roof construction, along with specifications for glulam, I-joists, wood structural panels, rim board and a new section on structural composite lumber. This section provides product descriptions for laminated veneer lumber (LVL), parallel strand lumber (PSL), laminated strand lumber (LSL) and oriented strand lumber (OSL). Engineering principles behind diaphragms and shear walls, fire-resistant construction systems, wind-resistive roofs, and noise transmission control, are also discussed. The 2007 edition includes several revised design tables including expanded recommendations for using APA plywood underlayment.
Visit the publications section of the APA web site to download a PDF of the publication or to purchase a hard copy.
