OX-IS R-3 Structural Insulated Polyiso Sheathing

Product Overview The OX-IS R-3 Structural Insulated Polyiso Sheathing is an advanced solution for modern construction, providing a blend of superior thermal insulation and structural support. Measuring 1/2″ x 4′ x 8′, this sheathing offers an impressive R-value of 3 and a compressive strength of 25 PSI, ensuring energy efficiency and durability. Designed to meet various building code requirements, the OX-IS R-3 functions as structural sheathing and continuous insulation, while also providing a weather and air resistive barrier. The non-reflective exterior facer enhances water resistance, and the closed-cell polyisocyanurate foam core provides high compressive strength and a continuous air barrier. This versatile product serves as a time-saving alternative to traditional exterior sheathing, ideal for both residential and commercial applications.
