Description

A direct replacement for standard 10- and 12-inch CMUConcrete masonry unit. Precast concrete block used to build walls. CMUs have hollow cores that can be filled with concrete onsite for additional reinforcement. The use of stronger, more lightweight types of concrete such as autoclaved aerated concrete (AAC) is becoming increasingly popular in CMU manufacture. , NRG Blocks have a cast-in EPSExpanded polystyrene. Type of rigid foam insulation that, unlike extruded polystyrene (XPS), does not contain ozone-depleting HCFCs. EPS frequently has a high recycled content. Its vapor permeability is higher and its R-value lower than XPS insulation. EPS insulation is classified by type: Type I is lowest in density and strength and Type X is highest. insulating thermal break in a "lock-and-key" configuration. The structure-as-finish blocks can be produced on existing equipment by local manufacturers, and are delivered ready to install. The manufacturer is working to eliminate the flame retardant HBCD from the EPS, so it should be possible to specify (or request) product without HBCD. The “effective R-value” of 22 cited in their literature (annual average modeling for St. Louis conditions) will vary depending on climate; the steady-state R-value is about 10 or 11, but the temperature-moderating insulated mass can be beneficial.
