NRG BLOCK = SIMPLE COMPLETE LOW CARBON SOLUTION Low embodied carbon (coming soon) + Low operating carbon (here today). One NRG Block = One Complete Wall. No additional insulation needed. Zero thermal bridges. Follow the Science! NRG block was used in the world's largest and tallest Passive House project (at the time of its completion in 2017), Cornell House residence hall.

Architectural Products Magazine 2022 Product Innovation Award Winner Judge's comment: "A nice option for highly sustainable projects." (12/15/2022)

NRG Block is a popular low-carbon solution for innovative owners, designers, developers, and engineers. Why choose NRG Insulated Block? Because NRG Block delivers cost-effective energy-efficiency in a sustainable, resilient building envelope. NRG Block pays for itself in energy savings.

What is NRG Block's secret?

No secret. NRG's interior concrete layer absorbs and stores energy.


Continuous insulation (with zero thermal bridges) keeps more energy in your building and keeps Mother Nature out.


NRG's exterior concrete layer adds an attractive, secure, fire-safe, resilient, low maintenance finish.

NRG Block acts as a rechargeable thermal storage battery that can last hundreds of years.

Which is better? NRG Block, or other insulated block? NRG block (left) has zero thermal bridges. Other insulated block (right) has two thermal bridges. Why do thermal bridges matter? Because energy crosses thermal bridges. Everytime it does, it wastes energy and money. Compare the standard block wall (top below)with an NRG CICMU (Continuously Insulated Concrete Masonry Unit) wall (bottom below). Warmer exterior walls in cold temperatures waste money as more energy exits the building.

About NRG Block: Proven track record: NRG Block lowers carbon in over three hundred high-performance buildings in the last twenty-five years. Winner: NY State Governor's Award for Energy Excellence. NRG is one of just thirteen game-changing inventions chosen to exhibit at the 2015 US Innovation Festival, held at the Smithsonian National Museum of American History in Washington, DC.

Testimonials:

Chaves Bakery, CT
“We have found even with the heavy rains we experienced this pass month, the integrity of the NRG Wall System has not been compromised, which as you know, is critical to our operations.”Vito Catale, General ManagerChaves Bakery (Constructed 1998) – Bridgeport, Ct.
NRG home in Houston, TX
“After months of researching the numerous masonry block products available to us, we finally found the only block suitable for our Houston climate. We so believed in the NRG-ICMU Wall System, that we bet (and built) our home on it. With enormous energy savings, security of a truly strong home, and unmatched beauty, our family is definitely the big winner!”Brenda Jones – Homeowner
Convenience Store, PA
“….even with three times more square footage (than the original store) we are paying less for energy than we did in the old building.” Don Reed."It has been over thirteen years since Don Reed opened his 6800 square foot market and to this date, he has never installed the 10-ton air-conditioning unit that was recommended by his mechanical engineering consultant, nor has he ever run his boiler for the radiant floor heating coils that were installed into the masonry floor." Quoted from the NCMA (National Concrete Masonry Association) Magazine
