Product Description

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.

    This product states that repair parts will be available to the customer but that on-site support will be provided to the customer by the manufacturer. This is not practical for an installed base of more than ~50 units. The global distribution to both Africa and India will require 24 x 7 staffing and when repair is required the unit will either need to be returned for repair or repaired on site. If the product is simple enough that the user can repair most issues than service instructions will be required. Sending out someone from the factory to support each product is not practical.
