The Thermal Properties of Wood—Data Base

Source

A data base of steady-state thermal properties for 15 wood species representative of those used commercially in building construction has been developed from available test data. Selected mean values of conductivity, density, moisture content, and thermal resistance are tabulated for representative groups of softwoods and hardwoods. The methodology for organizing the test data incorporating ASTM standards on wood is presented, and the statistical methods utilized for the empirical analysis are discussed. A proposed table of thermal design coefficients for softwoods doubles the reliability of predicted values currently listed in the ASHRAE Handbook of Fundamentals.

All test data are documented in a format suitable to a broad range of user groups. Design professionals undertaking computer modeling of composite assemblies and systems for building energy analysis will find the data base a useful reference tool. Recommendations on the need to verify the steady-state thermal properties for wood and wood-based building materials are presented and discussed.
