Wood Moisture Content and the Importance of Drying in Wood Building Systems

Technical Topic

Moisture management is one of the most critical factors in the long-term performance of wood building systems. Moisture problems can cause costly and potentially hazardous structural deterioration and possible health risks.

This publication is designed for: designers, builders

This publication explains how moisture content affects wood structural products during construction and throughout a building’s service life. It includes guidance on acceptable moisture content thresholds, the risks of trapping moisture in vapor-impermeable materials and best practices for roof and wall assemblies.

Key sections include:

  • Wood moisture content

  • Unvented attics

  • Wall systems
