Latest on Low-GPW XPS Board Insulation?

Greetings all,

Does anyone have the latest on status and availability of low-GWP XPS board insulation? I understand it is coming very soon, and I’m assuming that I would be able to find it by now if it was available as manufacturers would be eager to promote it, but seems like it is still a thing of the future. Thanks in advance for any info!

Best,

Owens Corning is scheduled to have a reduced GWP XPS board insulation available no later than Jan 1, 2021. I expect the official data sheet and an updated EPD will be released late this year.

Thanks Cheryl, I appreciate the update - I figured Owens Corning would be early to the gate with this, good to have expectations set on timing for projects under development. I’ll keep my ears open.

If anyone has info from other manufacturers to share, thanks in advance!

Cheryl - do you know what type of blowing agent Owens Corning plans to use for that reduced GWP XPS product? Is it HFO?

I’m interested if DuPont (formerly Dow, there was a merger apparently) is also planning to release a low-GWP XPS product. I reached out to DuPont awhile ago but never got a good answer. I see the DuPont Styrofoam product a lot: https://www.dupont.com/brands/styrofoam.html

Mark, not sure if you were on our ECN Vancouver webinar earlier this week, but we just uploaded all of the talks onto YouTube. This is the talk from Paul Lewandowski from Owens Corning, which may be of interest.

Also, I came across this announcement from DuPont. At the end of this press release, it says that:

DuPont expects to begin shipping Styrofoam™ with the DuPont oval effective Jan. 1, 2020, and newly formulated low Global Warming Potential (GWP) Styrofoam™ starting Jan. 1, 2021.

The blend we will be moving to has a GWP < 100 and there is ongoing development to further reduce GWP to 0. I can’t remember if Paul mentioned more detail in the video that Anthony has posted.

DuPont is presently working on implementing a new reduced GWP STYROFOAM TM insulation in order to meet the upcoming HFC regulations and provide our customers with a lower embodied carbon option. The reformulated product will have reduced embodied carbon while continuing to deliver the superior physical and thermal performance associated with STYROFOAM TM brand insulation.

As was indicated in the press release, this new formulation will be available by Jan 1, 2021. The R&D team at DuPont has done a great job to continue driving this work, despite the challenges of Covid-19, to meet this deadline! Please reach out to your local sales rep or go to https://www.dupont.com/building/contact-us.html to get more information.

Thanks Cheryl and Michal for these updates, very helpful! I expect you’ll be releasing EPDs in advance/in concert with the product release? I look forward to it, best of luck with the developments.

Cheers,

Extremely helpful question and thread, all.
