Thanks for following along! I actually think Rockwool is great for certain applications, especially roofs. I regret including it in this video! It does require a bit of processing but is generally a pretty low carbon footprint. Its great on roofs because of its high R value, waterproof and fireproof properties. Its a great when used as exterior insulation. Hope that helps!
there are additives to these now the stop fire, mold, etc... not a fan but it works much better than the alternatives. Home designs in the US make it easier to install and do it well. The moisture mitigation caused by air leakage is far superior with spray foam. By many definitions of eco-friendly and environmentally-conscious it works because of the short-term benefits such as no drafts, immediate savings on heating, and long-term savings in money from heating and not needing to replace wood and walls due to air leakage causing rot.
Totally understand your point from a building science perspective and with conventional framed wall systems. Just exploring alternatives here for those who want a more naturally based home from a materials perspective.
Thats a great question! I'll have to look into that a little closer. From what I understand PFAs are more prevalent in coatings and adhesives, so would mostly be a concern for the air barriers and not the insulation. I think there are some water based air barrier sealants out there that may be a good option, like Prosoco. I will look into these a little further! Learning more and more every day!
The real ecology issue is we're building structures with wood and have several industries developed around that. It's crazy considering the superior alternatives used throughout the world.

What are your thoughts on rock wool for insulation? Great videos! (Just came across your channel & binging through your library! 😂)

@christinaransbury Thank you! Yes, I was thinking it would be great for the exterior envelope. 👍

well done video!!
Thanks for watching!
What about pfas in any if these materials?

I agree! A lot of mass walls out there that are more efficient and less risky! Primarily and issue in North America
I feel you should have at least discussed fiberglass and rockwool
good point! I could elaborate on other options in another video
