NRG Insulated Block creates insulated thermal mass, a complete separation between the interior and exterior block components. NRG is the only commercially available block that features zero thermal bridging, which enables it to achieve a very high effective R-value (R-22).

ICON Inserts are molded from expandable polystyrene. The design of the insert allows it to compress so it will fit the cores of all masonry units with just one size. Inserts are placed in the cores of the block at the block plant. By placing inserts in blocks, there is a significant improvement in the thermal efficiency of masonry walls.
