Wood frame, steel frame and concrete block walls are “Hollow Wall” systems consisting of several pieces held together with nails, screws or mortar. A reinforced concrete wall is a one piece “Solid Wall” system that is many times stronger and provides a massive solid barrier of protection for a home. Insulation can be applied to the surface of the wall to provide and uninterrupted envelope around the home. We also offer the benefits of insulated concrete roof systems.
