Styrofoam™ brand square edge insulation is an extruded polystyrene foam (XPS) insulation board that meets the needs of the commercial foundation and building floor slab market and can also be used for attics, foundations/slabs and crawl spaces in residential applications. With more than 60 years of proven performance in wet environments, the closed-cell structure of Styrofoam™ brand square edge extruded polystyrene foam insulation resists water pickup, enabling it to retain a high R-value over time, a necessary property in wet, below-grade commercial foundation applications.
Styrofoam™ Insulation Board, 8 ft Length, 4 ft Width, 1/2 in Thickness, Polystyrene Foam, 165 deg F, Compressive Strength: 25 psi, Resists: Impact, Water, Weather
| Resists | : | Impact, Water, Weather |
- Bonds dry, treated, damp and frozen surfaces
- Can be used under almost all weather conditions
- Enhanced productivity
- Excellent adhesion
- They are easy-to-handle, cut using a utility knife or serrated blade and install
- Have a minimum compressive strength of 25 psi and a flexural strength of 50 psi
- Designed to ensure energy efficiency and minimize on-site cutting and waste
- Resistant to degradation from soil components and will retain insulating performance characteristics after prolonged exposure to moisture
- Provide a secondary barrier against groundwater leakage
- Help protect foundation damp-proofing and waterproofing, especially during backfilling
- Minimize the freeze-thaw cycling of the foundation, reducing the potential for cracking
- Warm the foundation, reducing the potential for condensation
- Will not corrode, rot or support mold growth
