Insulating Concrete Forms sandwich a solid reinforced concrete core between two 2.5″ thick panels of dense EPS foam. This foam is extremely good insulation and delivers unparalleled energy efficiency. Why?

The heating or cooling experienced during the day or night is stopped from influencing the inside temperature through both the EPS foam insulation and the concrete core. While the EPS foam works as an effective insulation it’s the thermal inertia of the concrete core that adds the greatest advantage. The concrete is heavy and dense and resists changing temperature. Think about the evening after a hot summer day when the sidewalks and streets are still warm late into the night. The concrete, once heated, stays warm for a long time. The opposite (cold concrete) is true as well. This thermal inertia of concrete helps stabilize the wall temperature. Combined with the insulation on both sides of the wall, preventing either exterior temperature changes or interior heating and cooling from affecting the wall temperature on the other side. By staying so stable, the inside temperature must only be conditioned to change a few degrees either direction, requiring very little energy.
