Hey guys I always appreciate the information. I own a crawl space repair company in Greenville SC (A Healthy Home). I have been doing it for 14 years and my family built the first unvented crawl space (by code) about 18 years ago in NC. It's refreshing to see another company on point with true building science when it comes to the crawl space...it's not rocket science but there are some key points that are critical. Over a decade ago everyone thought I was crazy to seal up the vents code required lol. Anyhow, I have always steered away from sealing the rim joists because of fear of trapping moisture in the wood. I agree it's a huge benefit and would love your feedback on a foamboard that would allow it to breath or wick moisturs
Yes, we have the same concerns which is why we dry the wood first then install an EPS board that allows some moisture to wick, along with moisture management like a dehumidifier and our Ninja way of encapsulation. But if there are any areas on the outside of the home that are compromised and allow water to intrude, like bad flashing or deck bolts wicking water, it's best to not install.
Dept. of energy in the state of Alabama says, that you cannot insulate a rim joist, you have to be 3 inches below the floor joists. if you do insulate with foam insulation it voids your termite contract.
Hmm... Can you provide a link to the DOE requirements you're referring to? We can't find any information about it and have seen several companies in the area providing rim joist insulation as a service.
Yes! Pro for spray foam. The install is easier than lugging in a foam board. Con is you have to find the right spray foam and you need to make sure that it is consistent all the way through which can be time consuming
I'm sorry to hear you're having trouble finding a good contractor in your area. Hopefully we can get a location opened up there soon! In the meantime, here is a video we made about how to choose a good contractor that may help: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pBSOBByvgtY.html
Building code requires batt/fiberglass in open crawl spaces when built, but we feel air sealing them is better as long as wood is kept dry all the time and is dry before installing.
@@CrawlSpaceNinja yea I can't afford incapsulation. But I'm gonna reinsulate and was just wondering your thoughts on the rim joists. But you answered my question at the end of the video.
Hello my crawl space is encapsulated. There is no insulation in my crawl space. I have a loft style home. The upstairs stays super warm. The down stairs says cols as all the hot air is raising. Would insulation in the crawl space help? Thanks
