Extruded Polystyrene

XPS has a higher moisture resistance than many insulations combined with low dust. Typically used as fabricated pipe insulation for low-temperature pipe applications. The unique closed cell structure of extruded polystyrene insulation makes it highly resistant to moisture while retaining its R-value year after year even following prolonged exposure to humidity, condensation, ground water and freeze/thaw cycling. Tough compressive strength adds to the significant performance benefits of extruded polysytrene. XPS is not recommended where sustained temperatures exceed 140 degrees Farenheit.
