Why is it critical to respect and maintain an NRG spec?
As energy codes evolve, owners demand (and the world needs)
a wall system that delivers high performance, high return on investment (ROI), and much less carbon.
Each NRG insulated cmu features truly continuous insulation with zero thermal bridges. The science is clear: energy transfer across thermal bridges decreases a wall's efficiency and increases building operating costs.
Owners (often taxpayers) and designers who specify NRG deserve to get NRG's continuous insulation. Substituting inferior products while claiming them "as equal" can result in higher operating costs for the life of the building. Unacceptable.
NRG's 8" full and half high units are the industry's only load bearing, continuously insulated 8" cmu's.
Accept the challenge.
Reap the rewards.
NRG Block has a learning curve, but mastering NRG can win jobs and strengthen the masonry industry.
As with anything new, the first day on the job with NRG can be challenging as you get used to NRG's quirks. By the second day, most professional masons find their groove with NRG.
Years ago, we spoke with the national director of training at the IMI in Washington. He was confident that he could train any professional mason to install NRG with near normal productivity in one day. Masons report production numbers 15- 20% lower than standard cmu walls when installing NRG. Watch the short video of masons laying NRG, and check out the production numbers on this page.
The guys in the video told us that NRG was a new challenge that they welcomed. They accepted it. They mastered it. Just another day at the office for true professional masons.
Getting the numbers right.
It's crucial to accurately estimate productvity numbers, especially when you are installing something new.
Your hard work as a master craftsperson deserves to be fairly rewarded.
Ths following information is from a couple professional masons. Of course every project is different, but we want to share their NRG experience with you.
The first guy, Cory, is a young, hard charging guy in St. Louis, an energetic young face in a graying profession. Cory and another mason and a block tender installed 400 NRG 8" ground face units per day in a fully-grouted, fully-reinforced NRG 8 wall.
Steve Richard is a very experienced mason who also teaches masonry arts at Alfred State College in Alfred, NY.
Steve has installed a couple NRG buildings, most recently a highly reinforced fire station in Genesee, PA. He estimated production for the NRG 12" (66lbs) at 175 blocks per day for his two person crew. Steve estimates production for a lightly reinforced straight run NRG 12" wall at between 250 and 300 blocks per day for a two person crew.
