NRG Insulated Block
NRG Insulated Block has embedded insulation in concrete masonry units.
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
6 – 12 USD
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.
Detailed schematics (in AutoCAD or REVIT format) are available via email upon request. An informational PowerPoint presentation provided by NRG Insulated Block is available for download.
For questions regarding NRG insulated block installation, you can contact them through their website or reach out to individual manufacturers/distributors.
It is unlikely that repairs are needed (see Lifecycle section), however further blocks can be ordered from manufacturers/distributors should sections of a structure need to be rebuilt.
NRG blocks are designed for permanent construction projects
Construction Cost Savings and Operational Cost Savings are performance targets specified by the manufacturer.
NRG Insulated Blocks have undergone structural performance tests and a thermodynamics assessment.
Testing organisations include Villanova University, Energy Management Inc., Pennoni Associates, and Green Building Advisor
Any installation of NRG Blocks should conform with local building codes and construction safety requirements.
Termobuild floor system is recommended by NRG as a complementary product.
ASHRAE – American Society of Heating, Refrigerating, and Air-Conditioning Engineers
ASTM – American Society for Testing and Materials
Testing organizations have conducted standard compression and lateral load tests. Economic advantages, studied primarily by the manufacturer, makes comparisons to standard recognized wall assemblies while taking associated heating and cooling costs into account.
