Insulating a Floor Over an Unheated Space

[@shaolinmonk8620]

This is exactly what I was looking for ...Thank you so much for the video... great work and good explaination.

I’d like to see how you handle the joints in the comfortboard in this application.

How does this do in Louisiana with high humidity during the summer? I have a raised home and wood floors so its pretty cold in the winters here.

Hello , I just came across you video . I am also considering using the Rockwool . I live in South Carolina and it gets very humid here in the summer months . Some animals got under our mobile home and got thru the under belly vapor barrier and destroyed the under belly & nest thru the insulation . So I need to remove the under belly & replace the insulation. Would you not apply a wrap to the underside of the mobile home ? Thanks

Will you run into any issues with adding comfort board IS as far as closing vapor barriers or trapping moisture? I know those products are both somewhat breathable. Just wondering if I should do that extra step under my crawlspace that is not encapsulated

What would you do differently if this was to become a heated four season Room?

[@shakeyojunk]

Can I do this for a vented crawl space?

[@ROCKWOOLNorthAmerica]

yes!

@@ROCKWOOLNorthAmerica if I did this in a vented crawl space, would I need a vapor barrier on the floor or can I leave the floor dirt? I’m in climate zone 3 (Los Angeles)
