Styrofoam™ Brand Plazamate™ XR Insulation

DuPont™ Styrofoam™ Brand Plazamate™ XR Foam Insulation is next generation in the evolution of high-performance closed cell insulation that allows extra design flexibility for architects and engineers by optimizing roof thickness, reducing expensive commercial roof building alterations required for meeting the latest building and energy codes, and assists in reducing overall project costs.

It is also reusable, durable, easy to work with and resists compressive creep and fatigue, which delivers long-term compressive strength and high R-value.

Styrofoam™ Brand Plazamate™ XR Insulation is an extruded polystyrene insulation available in compressive strength of 60 psi (415 kPa) and is ideal for exposed wet applications, and has the following characteristics...

  • Provides superior resistance to water absorption, water vapor transmission, and freeze-thaw cycling
  • Features exceptional R-value and R-value retention, in typical construction and in demanding cold, wet, humid, changing environments
  • R-value of 6.7 per in. @ 75°F (24°C) mean temp.
  • R-value of 7.4 per in. @ 40°F (4°C) mean temp.
  • R-value of 7.7 per in. @ 25°F (-4°C) mean temp.
  • Ideal for low-temperature, geotechnical, high-load commercial and other in-ground or water-contact applications such as Protected Membrane Roofs, Green and Blue Roofs, Amenity Decks, and many others
  • Delivers long-term compressive strength in high-load applications
  • Resists compressive creep and fatigue

Why is this important?

This means that the insulation is able to deliver R6.7 per inch vs. R5. In addition to "more is better" this increase in R value can positively impact the total assembly in many ways...
