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.

New Regulations

GreenGuard XPS currently contains a zero Ozone Depletion Potential (ODP) blowing agent. New laws and regulations are being implemented to lower the Global Warming Potential (GWP) impact of the product.

  • These new regulation are overall very positive and Kingspan is fully in support of this effort
  • Our approach is a measured and customer focused approach

What You Need to Know


  • California, Washington, Colorado, New York, New Jersey and Vermont will begin regulating HFCs on 1/1/2021.
  • Regulations state that “No person may sell, lease, rent, install, use, or manufacture in the State…” XPS Billets and Boardstock that contain HFC 134a as a blowing agent.
  • All states allow the sales, import, distribution and installation of XPS products containing HFC blowing agent that are manufactured prior to 1/1/20201.

2 Types of Products and Where You Can Ship Them

  • All states allow the sales, import, distribution and installation of XPS products containing HFC blowing agent that are manufactured prior to 1/1/2021.
  • GreenGuard LG XPS products do not contain regulated HFCs so will be compliant to local regulation in all 50 states plus Canada.
  • Kingspan will continue to supply HFC product into Canada throughout 2021.
  • In the U.S., GreenGuard regular products produced after 1/1/2021 can only be sold and shipped to the states that currently do not regulate HFCs.
  • All GreenGuard XPS (LG and Regular) boards are printed with a date code. 
  • Anyone selling or shipping into a regulated area can only ship LG product or product made prior to January 1, 2021.
  • Distributors outside of the identified states will be able to purchase HFC material made in 2021. However, it is in violation of State regulation to then ship HFC material produced in 2021 into regulated areas.
  • Fanfold product from Kingspan uses a different blowing agent and is not affected by these new HFC regulations. In addition, the 11/18/20 price increase does not apply.
  • If you are located in a regulated state, you can drop ship HFC material to customers in unregulated states. However, Kingspan will not ship HFC 2021 material to your warehouse for shipment to an unregulated state.
  • If you are ordering product for a customer or project in a regulated location, regardless of your location, the product will be priced to include the appropriate price increase for that product.

Meeting Your Goals

  • GreenGuard LG XPS products will meet your sustainability goals in 2021 for wherever your project is located. It will meet the requirements of both Canada and US states that implemented the HFC regulations.
  • However, due to the high cost of a HFO blowing agent, GreenGuard LG XPS products will come with a price premium.
  • For a limited time, Kingspan will have HFC 2020 product produced prior to 1/1/21 available specifically for distributors in affected regions. While not as low as the LG formulation, Kingspan previously worked to blend our formulation to be below 550 GWP. This is less than 40% of HFC134a.
  • As the situation continues to evolve, Kingspan commits to our partners to work with you to complete this transition in the most effective manner. Please reach out if we can help.

Current Blowing Agent Regulatory Status
  • Canada and 15 States have issued or announced plans to regulate HFCs.
  • 35 remaining states have taken no action.
  • 6 states will begin the HFC ban on 1/1/2021.
  • The states of MA and Maryland announced enforcement date of 7/1/2021, with VA and DE possibly on 7/1/2021.
