Introducing the New Kingspan GreenGuard LG XPS Insulation Board

Kingspan is ready for this market transformation with the Kingspan GreenGuard LG XPS Insulation Board product! “LG” stands for Low Global Warming Potential formulation.

The Kingspan GreenGuard LG XPS Insulation Board product line will continue with our 25-year history of:

  • The same green foam color
  • The same high R-value of 5 per inch
  • The same wide range of compressive strengths including 25 psi, 40 psi, 60 psi
  • The same superior moisture resistance

There are also improvements and changes:

  • The new formulation will have a GWP (Global Warming Potential) of less than 50!
  • The board face print will be blue!
  • New literature specific to the LG product line with new product numbers: GG25-LG, GG40-LG, and GG60-LG. We believe these new product numbers will enhance the communications regarding which product a customer is requesting and expecting.
  • GreenGuard®  XPS LG (low GWP formula) is a premium product with ZERO ODP and <50 GWP.
  • HFC134-A has been completely eliminated.

This new product line is fully in support of the Kingspan Group’s world-wide Planet Passionate Initiative. Click Here for more information on Kingspan’s Planet Passionate initiative.
