Yes! Budgeting is a big one. I have a pricesheet that can help. Head over to my website to download that. I will consider this for a future video. Thanks for watching!
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!
@@christinaransbury Not very good in areas with rodents. They eat right through it and like living in it. As rodent proof roof / ceiling insulation it's better to use straw mixed with clay slip or stuff made of old newspapers and similar recyclables that is sprayed with rodent repellants like borax and boric acid (celluloid / cellulose wool, for example Werrowool). This might differ by area as some rodents may ignore some repellants. Rock wool is also hazardous to place, not as bad as some other artificial stuff but much worse than hemp and similar natural wools. The heat during production makes all kinds of tiny particles separate into the wool.
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.
Foam is the first thing rodents chew through to get to the warm inside. Second is expanded polysterene, third any type of rock or glass wool. All pose no serious barrier for rodents. Only old growth wood (thin rings making the wood more dense), dry clay mix, stone or metal make a home rodent proof.

I would greatly appreciate a video on how to budget our build! Thanks for being so thorough! Learned quite a bit.

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. 👍

What about pfas in any if these materials?

I feel you should have at least discussed fiberglass and rockwool
good point! I could elaborate on other options in another video

I agree! A lot of mass walls out there that are more efficient and less risky! Primarily and issue in North America

Right? Those are great points, thanks for sharing. Old growth wood
well done video!!
