My crawl space is ventilated. Should I insulate as well as use a dehumidifier?
Are you having problems? Is it cold in the house? Humid climate?
Wonderful Harmon, you are going about this project the right way. Here are some tips to get you started.
Whether you do yourself or hire out, consult again with the building inspector which would be best for your climate. What I do here in Zone 9 in Southern CA will be different than what you might need to do in a snowy or humid climate. Here is how to hire a contractor if need be.
Hermon,. Definitely insulate, this will keep your floor warm. The dehumidifier depends on how much moisture you have. Aloha!
Check out the website below. There are many things to consider depending on your exact circumstances. However, based on the most recent research, the conventional wisdom has changed and turning an unconditioned crawlspace into a semi-conditioned space without vents seems to be the preferred method. The idea that air flow in/out of the crawl space would reduce moisture problems turns out not to be true or at least not as good as people thought. A sealed crawlspace will supposedly reduce moisture problems and be more energy efficient, if done correctly.
