NOTES:
1. Temperature range and K-Factor data were compiled from current manufacturer's
published literature. Consult specific manufacturer's data for application
methods.
2. Special attention must be given to high humidity / high temperature
applications, specifically vapor retarder systems.
** See manufacturer's data for K-factor
*** Lightweight, excellent workability, combustible although some are
treated for fire retardancy (check manufacturers' data sheets for properties.)
K-value may change as these materials age.
