R values calculated
using parallel heat flow
R values taken from
National Concrete Masonry Association
|
|
* R means
resistance to heat flow; the higher the R value, the
greater the insulating power.
Limitations: This material is not intended
for use with temperatures
exceeding 190° for prolonged
periods of time. The
foam will not support a compressive load and should
not be used for floatation, overhead applications or
underground as a vapor barrier. |
