Ultra Energy-Efficient

With Quad-Lock you can build walls with your choice of insulation value, from R-22 to R-59 - the highest ICF R-Values in North America. Choose the optimum R-Value depending on your local climate and energy-saving goals. High insulation values combine with low air infiltration and the thermal mass of the concrete to keep occupants comfortable, healthy, and productive, while saving significantly on energy costs.
