Engineered wood products are used in a wide range of residential, commercial and industrial building systems, from floor, wall and roof assemblies to lateral force-resisting systems and specialized industrial applications. APA provides the research, tested assemblies, code-recognized details and design guidance professionals need to specify and build with confidence.
Explore application-specific resources, span tables, construction details, code compliance information and technical publications for engineered wood systems and assemblies. Whether you're designing a floor system, detailing a shear wall, or selecting materials for a commercial roof, APA offers the tools and expertise to help you get it right.
Engineered Wood Floor Systems Built to PerformFloor systems do more than support loads—they influence comfort, durability, acoustics, and long-term performance. APA-rated wood structural panels and engineered wood framing products provide reliable solutions for everything from conventional subfloors to premium floor assemblies and fire-rated I-joist systems.
Explore resources, design details, and construction guidance to help you specify and build floor systems with confidence.
Building Better Wall SystemsWalls do more than define a building's footprint—they resist lateral loads, control air movement, support energy performance, and contribute to long-term durability. APA brings these considerations together through practical guidance on structural, energy, and resilience-focused wall design.
Designed to Span, Support & PerformRoof systems must do more than support roofing materials—they must safely transfer loads, resist lateral forces, and perform reliably over time. APA resources cover roof sheathing, diaphragms, and long-span framing systems for residential and commercial construction, backed by design data, span tables, and tested construction practices.
Engineered wood products support a wide range of roof designs, from conventional residential framing to complex commercial structures. APA guidance helps designers and builders evaluate system options, detailing requirements and construction methods to achieve efficient, practical roof assemblies.
Solutions for Demanding Industrial UsesThe performance advantages of engineered wood extend well beyond building construction. APA-rated panels are widely used in industrial applications ranging from concrete formwork and pallets to shelving systems, agricultural containers, and furniture. Explore guidance and technical information for applications where strength, consistency, and efficient use of materials are critical.
Successful building design requires more than structural calculations alone. Moisture management, fire protection, acoustics, and energy efficiency all influence how a building performs throughout its service life. APA's research-backed guidance helps design and construction professionals address these critical considerations with practical recommendations, tested assemblies, and code-recognized details.
