Engineered Wood Construction Guide

“Engineered wood” describes wood products that are engineered for structural applications. These products are made by combining wood strands, veneers, lumber or other wood fiber with moisture-resistant adhesives to form a larger composite structural unit.

This publication is designed for: architects, engineers, designers, builders, building officials

This publication is the ultimate guide to engineered wood products. It includes detailed information on plywood and oriented strand board (wood structural panels), glulam, cross-laminated timber, I-joists, structural composite lumber, typical specifications and design recommendations for floor, wall and roof systems, diaphragms, shear walls, fire-rated systems and methods of finishing. 

Key sections include:

  • Panel selection and specification

  • Glulam selection and specification

  • Cross-laminated timber selection and specification

  • Structural composite lumber selection and specification

  • I-joist selection and specification

  • APA Performance Rated Rim Board selection and specification

  • Construction with engineered wood products

    • Floor, wall and roof construction

  • Fire systems

  • Building systems
