Epitome foundation walls, a composite foundation wall system, employs a high-performance composites technology and can help residential home builders become far more efficient. The system is designed to replace vertically installed concrete, and it combines strength, integrated stud cavities for mechanicals, insulation, the top plate and a vapor barrier all in a single step. The walls reportedly offer better energy efficiency with an inherent R-16.5 insulation value and an airtight transition between the floor and foundation designed to make it more efficient than a standard concrete foundation. They also pass the NFPA 286 room corner burn test and therefore do not require covering with a thermal barrier such as drywall prior to occupancy.
