Owens Corning FOAMULAR 250 XPS Insulation Board - All Sizes

Product Code: OWCFOAM2503/4In

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
