EXTRUDED POLYSTYRENE (XPS) INSULATION

Improve Insulation Value of XPS Board

XPS rigid insulation uses an extrusion process with polystyrene, a foam blowing agent, and other materials. XPS is an excellent insulator, inhibits mold / mildew growth, may be used below grade, and is used in many commercial and residential construction applications.

Solstice® GBA is ideal for XPS insulation used in residential and commercial construction. It replaces HFC-134a and other fluorocarbon and non-fluorocarbon foam blowing agents.  Using our ultra-low GWP blowing agent increases the insulation value of XPS foam. This can translate into thinner panels required to achieve the desired performance, or higher thermal insulation value of panels with the same thickness.

Benefits of Solstice GBA for XPS include:

  •  Long-term insulation performance is 7% better than HFC-134a; 26% better than CO2
  • Nonflammable (ASTM E-681, EU A11) (unlike other gaseous blowing agents or hydrocarbon alternatives, which require flammability handling equipment)
  • Low Maximum Incremental Reactivity (MIR)
  • Low Photochemical Ozone Creation Potential (POCP)
  • Global Warming Potential (GWP) < 1, even lower than CO2
  • VOC-exempt (U.S. EPA)


XPS Foam Performance

20-25% Better Long-Term Lambda Than CO2-Blown XPS

Solstice® Gas Blowing Agent allows extrusion of thick, dimensionally stable planks with lambda values of 27mW/m.K or lower (per EN 13164 Annex C) depending upon machine configuration and co-blowing agent used.

Solstice GBA demonstrates:

  • Good thermal and mechanical performance
  • Lambda: 20-25% improvement vs. CO2 and similar to HCFC-142b and HFC-134a
  • Capability to extrude thick foam without capital investment
  • Capability to extrude low density foam
  • Compressive strength similar to HFC-134a
  • Dimensional stability similar to HFC-134a
