- Excellent long-term stable insulating performance at R-5 per inch
- Exceptional moisture resistance, long-term durability
- Lightweight, durable rigid foam panels are easy to handle and install
- Easy to saw, cut or score
- Scored Square Edge
- 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
