Non vented and encapsulated is the way to go? Do I still Need a dehumidifier in there? I will be digging, installing a perimeter drain, 4” of gravel adding 2” to 4” of insulation, moisture barrier and 2” of concrete Edited I fixing it because previous owners Didn’t even have a moisture barrier under the kitchen floor all of the dirt was exposed and the entire floor was rotted due to high levels of moisture and termites 🤷🏻♂️😩
@@HomePerformance nothing funny here. In bed with the flu. Just wondering how much diff it makes. Its rather cosy in sub floor since i fitted the ground sheet and insulation. The plumber loved it!
@@HomePerformance lol. better today. tho nothing worse than off work during peak season.....or during building of your dream home. at least there is entertaining video's on utube. many thanks for the vids.
I didn't see that twist ending coming :) I thought you were going to say the best way is to NOT encapsulate the space, like mies van de rohe's Farnsworth house. Interesting twist saying that the best way is to fully encapsulate. I'll stay tuned for more info, and visit your website
I was surprised by your comment on non-vented crawlspaces almost always being a better option. I’m a big believer in non-vented crawlspaces but I’m not sure they make sense (to retrofit at least) in dry climates. Sure, in humid climates vented are a disaster, no disagreement there. But if you live in a dry/mild climate with an existing crawlspaces and no HVAC down there I’d argue it’s better and more cost effective to simply add a proper air barrier at the subfloor level. New construction I’d still opt for non-vented but I believe retrofit is more nuanced.
You’re right, that’s why we said ‘almost always’. Great thing about home performance is there are always details to consider. The world needs people like you to analyze the angles, which is why performance contracting isn’t scalable. It takes local experts, and we hope people pick that up for certain from ‘Home Diagnosis’.
Home Performance thanks for responding C! This is a topic I’ve gone back and forth on over the years, it’s funny how your views change every time you learn a bit more and peel back another layer of the onion. Hey you should consider attending the next Fine Homebuilding Summit, the number of Building Science geeks you get to talk to is amazing and I think you’d love it.
