EPS roof insulation
is substantially less expensive per R value than any other type of insulation.
Unlike other products the R value of EPS insulation is permanent because
the cellular structure contains only stabilized air. Aging has no effect
upon the performance of EPS.
Using
EPS to fill corrugations on metal roofs is an economical way to provide
a level surface for the finish insulation. Almost any configuration
can be cut and installation is simple.
