Atlas Roofing's EnergyShieldXR also provides superior durability, with a 25psi compressive strength to withstand soil, backfill, or hydrostatic pressures. The foil facers remain stable under heat and UV exposure, while pre-scored lines at 16in. and 24in. centers simplify cutting and installation. Its GREENGUARD Gold certification contributes to LEED credits, supporting energy efficiency and building sustainability goals without compromising structural integrity or thermal performance.

• Its closed-cell polyisocyanurate core delivers high thermal resistance per in.
• Foil facers resist moisture uptake even in below-grade applications
• A compressive strength of 25'¯psi ensures durability under backfill and load
• Designed for under slab foundation
• Manufactured without ozone-depleting blowing agents for environmental safety
