*The listed R-values were prepared making use of published data from the following sources: National Concrete Masonry Association (NCMA) TEK No. 6-2A, American Society for Testing and Materials (ASTM) Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation, C578-04. Increases in the R_T values listed can be accomplished in several ways: increasing the thickness of the EPS Insulation, adding to the thermal value of the interior finish material of the wall or varying the density of the concrete.

Detailed drawings, step-by-step instructions and a pre-grouting checklist are found in the IMF^® Wall System Installation Manual.
