XPS Residing Board 25 PSI – R Value 10

With its extruded polystyrene (XPS) construction, Kingspan GreenGuard XPS Residing Board does not absorb water, is not a food source for mold, and is not subject to moisture-related damage and deterioration. An R-Value of 5.0 per inch of thickness makes it an excellent thermal insulator that increases the energy efficiency of your structures, and it retains its insulating properties over time. The board also provides an extra barrier against moisture infiltration. Choose between a square edge (CM) and an interlocking shiplap edge (SL) that helps reduce air leaks at seams and gaps.

  • Highest thermal performance
  • R–value of 5.0 per inch of thickness provides excellent energy efficiency
  • Water absorption of only 1/10% by volume
