Atlas EnergyShield XR Foil Faced Both Sides Above & Below Grade Polyiso Insulation is a versatile board that boosts thermal efficiency for both above- and below-grade applications. Designed for Type I–V construction, it protects exterior walls, under-slab foundations, and more with durable, moisture-resistant performance. It’s the kind of insulation that quietly handles extreme temperatures so you don’t have to micromanage comfort—even when the weather acts up.

Key Features & Design

• Dual-sided foil facing on both sides provides excellent thermal resistance and radiant heat reflection, dramatically reducing heat transfer.
• Versatile applications suitable for exterior walls (wood or steel studs), masonry, concrete structures, and under slab foundations in Type I–V construction.
• Moisture control & mold resistance to promote a durable, stable building environment and long-lasting performance.
• Safety & compliance meets ASTM E84 and UL 723 for flame spread and smoke development (Class A), with broad code approvals including ASHRAE, IECC, and IBC.
• Robust physical properties delivering excellent compressive and flexural strength, backed by a tested 25 PSI compressive rating.
• Extreme temperature tolerance designed to perform from -100°F to +250°F, ensuring energy efficiency across diverse climates.
• Energy-first performance high thermal resistance and radiant heat reflection help create an energy-efficient building envelope with fewer run-ins with your utility bills.
