Owens Corning FOAMULAR 250 Extruded Polystyrene (XPS) Insulation is a closed-cell, moisture-resistant rigid foam board well suited to meet the needs for a wide variety of building applications. FOAMULAR 250 XPS insulation board is great for many residential and commercial construction applications such as wall furring, perimeter/foundation, cavity wall, pre-cast concrete, under a slab, crawl spaces, sheathing, and other applications.
| Thickness | Sq Ft Per Board | R-Value |
|---|---|---|
| 3/4" | 32 Sq Ft | R4 |
| 1" | 32 Sq Ft | R5 |
| 1.5" | 32 Sq Ft | R7.5 |
| 2" | 32 Sq Ft | R10 |
| 2.5" | 32 Sq Ft | R12.5 |
| 3" | 32 Sq Ft | R15 |
| 4" | 32 Sq Ft | R20 |
Features
- 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
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
