Energy efficient. Resilient. Sustainable. Budget friendly. Made in USA. Zero Energy Ready. NRG Block.

Why is NRG Insulated Block the world's best block? Because NRG Block is the most cost effective and energy efficient.

How does NRG Block (the world's best block) work?

NRG's interior concrete layer absorbs and stores energy.


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


Exterior concrete layer adds attractive, secure,

fire-safe, resilient, low maintenance finish.

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

NRG 8" block, pictured at left, has zero thermal bridges, while Omni block, pictured at right, has two thermal bridges in every block.

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.

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.

“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

“….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."
