NRG Insulated Block
NRG Insulated Blocks is a system of Continuously Insulated Concrete Masonry Units (CICMU’s) that combines the structural use of masonry with typical rigid insulation, locating the thermal break towards the outside of the block and maximizing internal thermal mass. The product is patent protected and is produced and sold in the United States.
Manufacturers and distributors are located across several states in the US and are listed on the NRG website.
Prices can range from $6.50 USD per unit to as much as $12.00 as transport is usually included in the price and distances to construction sites vary.
Although there is no other product to date on the market that has insulation incorporated into the building module, other products that clients may consider are masonry units such as Quik-Brik, Insulated Concrete Forms (ICF’s), precast sandwich panels, Structurally Insulated Panels (SIPS), and cavity or brick veneer walls.

The blocks are available in standard 8″, 10″ and 12″ depths, and full and half heights. The product comes in brick and concrete finishes.
For questions regarding NRG insulated block installation, you can contact them through their website or reach out to individual manufacturers/distributers.
It is unlikely that repairs are needed (see Lifecycle section), however further blocks can be ordered from manufacturers/distributers should sections of a structure need to be rebuilt.
NRG blocks are designed for permanent construction projects and therefore disposal or recycling options and directions are not available.
Any installation of NRG Blocks should conform with local building codes and construction safety requirements.
An average of the maximum compressive strength a typical structure could withstand with this building material. Units: σ (N/mm2)
An average of the maximum loads/forces perpendicular to the compressive forces that a typical structure could withstand with this building material. Units: σ (N/mm2)
A seismic design category expresses an area’s likelihood of experiencing damaging effects of an earthquake (A(low), B, C, D0, D1, D2, E(high)). This parameter denotes the highest acceptable SDC for the material.
Climatic zones appropriate for construction based on a material’s availability/feasibility in each climatic zone.
