Applications
• Slows the transmission of water vapor and moisture in masonry walls
• Provides continuous insulation over wood or steel stud framing, in insulated concrete sandwich panel walls, in masonry unit cavity walls, or when used with non-penetrating, surface mounted furring systems over masonry or concrete walls
• Insulates and retains its properties in below-grade perimeter and foundation applications, or directly beneath the concrete slab to complement the insulating sheathing envelope around the building framing
• FOAMULAR 250 XPS insulation is great for below-grade applications. FOAMULAR XPS insulation is resistant to degradation from the components of common soils
and will retain its insulating performance characteristics even after prolonged exposure to moisture
• Extruded Polystyrene Provides a weather-resistant barrier (when joints are sealed) to enhance the building’s resistance to air and moisture penetration
