This is the first time I've seen anyone use mineral fibre - even the 110 - for the underslab instead of EPS or XPS. As a huge fan of mineral fibre, I would love to know if the slab stays perfectly intact. Great move!
If I understood you correctly, the rockwool is laying on the gravel and in between you're going to have an air pocket, right? Why did you choose for this option, rather than to sandwich the rockwool directly to the underside of your flooring? Wouldn't that cause the heat from the radiant heating system to not be able to travel downwards better? Nice short video btw! Straight to the point.
Close. The Rockwool sits on the gravel and then we put an air barrier directly on top and then put directly on top of that. Essentially the concrete sits right on the insulation. No air pocket
You mentioned that there would be a vapor retarder or vapor barrier between the insulation and concrete. Why are you putting the barrier between the insulation and concrete and not below the insulation? I know rockwool is tough stuff, but it seems like putting the barrier on top of the insulation will lead to the insulation swelling and shrinking and degrading over time.

The pencil you were using looked like a high quality pencil !
Whoah, wayback playback. I was a huge fan of Love It or List It, and excited to follow along. Great to see modern building science being applied!
Fun video!! I like learning new things and seeing how you do it Todd!
More to come!
Thanks!
@@talbotlife excited to see more 😊

I like see your vídeos Todd!
Wouldnt the rockwool get moist from the vapors coming from the ground?
Wiil the stable board stop the radon?

Sorry doesn’t make any sense , put it under the Floor ?
