BARRICADE Insulated Subfloor is the first and most important step towards creating a new living space as warm and comfortable as any other space in your home. BARRICADE is the one-step engineered subfloor solution that is specifically designed for basements. BARRICADE Insulated Subfloor combines high density Oriented Strand Board (OSB) and extruded polystyrene (XPS). With an R-Value of 3.2, BARRICADE Insulated Subfloor provides maximum insulation strength against the cold concrete. BARRICADE Subfloor Air Plus softens finished floors to cushion against the hard concrete. It/s sturdy confection supports over 6,600 pounds per square foot. BARRICADE Insulated Subfloor panels have been designed with patented Air Gap technology that helps protect against moisture, mold and mildew to keep basement floors dry, comfortable and cozy for years to come! XPS' closed-cell structure resists moisture and maintains R-value. BARRICADE Insulated Subfloor panels features tongue and groove design that snaps into place for fast and easy installation; a typical 500 square foot basement installs in an afternoon. No worry with the limited 25-year warranty.
