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, BARRICADE Insulated Subfloor makes floors feel warmer. Enjoy a warm, comfortable basement for years to come! XPS' closed-cell structure resists moisture and maintains R-value. BARRICADE Insulated Subfloor panels are fast and easy to install; a typical 500 square foot basement installs in an afternoon.
