The development of a National Institute of Standards and
Technology (NIST) Standard Reference Database for the
thermal conductivity of building materials is presented.
The source of the data is the collection of thermal
conductivity measurements produced by NIST from 1932 to
1983 using the NIST 200 mm guarded-hot-plate apparatus.
During its service, the apparatus was considered the
U.S. National Standard for measurements of thermal
conductivity of building materials and was instrumental
in the early development of ASTM Test Method C177 for
the guarded-hot-plate method. The database currently
contains 2175 records of thermal conductivity data for a
variety of thermal insulations including cellular
plastics, corkboard, glass fiber and other mineral fiber
insulations as well as other building materials such as
fiberboard and light-weight concrete. The final product
will be available for public distribution on the
Internet through the World Wide Web.
