1. Compressive resistance measured at 10 percent strain is not intended for use when ENERGREEN insulation will
be used  to  support  long-term  compressive  loads.    Contact  your  Plasti-Fab  technical  representative  for additional information.
2  For additional information on thermal resistance requirements refer to ASTM C578.
3. ASTM  Test  Method  C272  water  absorption  requires  24  hours  submersion  of  specimen  under  water.  
The  water absorption values above are applicable to specific end-use design requirements only to the extent that the end-use conditions are similar to requirements stated in the test method.
