The solid mass of the Nudura wall has some very unique qualities. The monolithic concrete is layered between two continuous panels of 2 5/8” (67 mm) EPS foam, which isolates the concrete and significantly reduces the flow of heat through the wall.
Since Nudura walls have a high storage capacity with low thermal conductivity, it provides the most useful level of Thermal Mass. This helps to stabilize the internal temperature from day to night temperature fluctuations and provides a largely self-regulating environment. Reducing the amount of mechanical equipment needed for heating and cooling means less energy consumption, resulting in greater cost savings throughout the year.
Less to cool and heat. Buildings with exterior Nudura ICF Concrete Walls, also utilize less energy to heat and cool than similarly insulated buildings with wood or steel frame walls.

Nudura Insulated Concrete Forms have a tested R-Value of 23.59. Click here for more information on Thermal Resistance Calculations.
TECHNICAL INFORMATION ON R-VALUE & THERMAL MASS
The combination of these 3 elements together limits the thermal conductance of the finished Nudura wall assembly to a maximum transmission rate of 0.04 BTU/hr∙ft2∙ºF (0.24 W/m2∙ºC)” when tested to -31ºF (-35ºC)
