Atlas EnergyShield® XR is a high-performance rigid insulation board engineered to deliver continuous thermal protection for exterior wall and foundation applications in both commercial and residential construction.

Manufactured with a closed-cell polyisocyanurate (polyiso) foam core and durable foil facers, EnergyShield XR helps minimize thermal bridging, improve energy efficiency, and enhance occupant comfort by reducing unwanted heat transfer through the building envelope. Designed for above- and below-grade use, it offers a standard compressive strength of 25 psi, making it well-suited for demanding wall and foundation assemblies. EnergyShield XR also helps control moisture while maintaining excellent long-term thermal performance.

Available in a wide range of thicknesses and R-values, it supports building code compliance and sustainable construction goals through environmentally responsible manufacturing processes, GREENGUARD Gold Certification, and contributions toward LEED credits. Its versatility, durability, and proven performance make EnergyShield XR a dependable solution for high-performing building envelopes.
