Energy Efficiency of
AAC
Cellular Structure is created by the unique manufacturing process. Millions of tiny air cells give SafeCrete AAC amazing insulating properties, reducing heating and cooling costs by as much as half.
Thermal Mass Inertia slows the transfer of heat through the wall. SafeCrete walls are typically 8 to 10 inches thick. The sheer mass of the wall causes heat to pass through more slowly. In temperate climates, this lag time allows the HVAC system to compete against the average temperature of the day, rather than the peak temperature.
The chart below demonstrates thermal mass inertia. In this study, one side of a 10-inch AAC wall was painted black to maximize heat absorption from the sun. A thermometer measured temperature changes on the exterior and interior surfaces over a twenty-four hour period. The exterior surface fluctuated over 126°F while the interior surface fluctuated only +2°F.

Wall Surface Temperatures
Low Air Infiltration also enhances the energy efficiency of SafeCrete buildings. Solid, single-component construction prevents the kind of air gaps that frequently occur around electrical outlets. SafeCrete breathes, but does not allow direct air penetration.
Whole Wall Coverage prevents thermal bridging. The illustrations at right show the solid nature of SafeCrete construction. Unlike frame construction, which leaves thermals gap at every stud and lintel, SafeCrete provides structure and insulation in a single component.
The energy efficiency of SafeCrete home insulation saves money during construction as well as in operation, since smaller HVAC units and less insulation are used.
