We believe in continuous R&D that allows us to provide the most innovative line of Insulated Concrete Forms in the market. The XR35 form, with its 4in (100mm) thick EPS panels, provide a significant increase in insulation performance. It is available with a 6in (150mm) and 8in (200mm) core as a standard form and a 90° corner form. The fastening strips remain 5/8in (16mm) below the surface of the EPS and are located at 8in (200mm) on center.
