The XR35 ICF Form features a higher R-Value due to its 4-inch EPS panels. It is available with a 6- and 8-inch core as a standard form and a 90-degree cornere form. The fastening strips remain 5/8 inch below the surface of the EPS and are located at 8 inches on center. Nudura says the forms are high-tech insulated concrete forms that have proven technologies to make building easier and faster.
