The NRG Insulated Block is a continuously insulated concrete block with zero thermal bridges. It has proven effective R-values of R-50+ in climate zones 5 and 6. NRG’s interior concrete layer absorbs and stores energy, while the exterior concrete layer provides an attractive, secure, fire-safe, resilient, and low-maintenance finish. NRG’s long thermal lag time allows for off-peak cooling and (electric) heating, so building owners pay less for off-peak utility rates and shift grid demand.
