Outsulation X is a high performance cladding system that serves as a single source for the air- and water-resistive barrier, continuous insulation and appealing finished appearance of the exterior wall. The system incorporates Dow X Energy Rigid Insulation to allow installers to meet higher R-values with just a two-inch thickness of insulation. It yields a 39 percent greater energy efficiency and 36 percent better impact resistance, compared with similar EPS-based systems with similar weight reinforcing mesh. Outsulation X meets both current and proposed ASHRAE design standards and IGCC/IECC code requirements for the use of continuous insulation. A single, professional sub-contractor can install this engineered, fully tested, code-compliant system.
