3/4 of my house is sitting on top of a crawl space. The walls are cinder blocks. The crawl space is anywhere between 2 feet and 4 feet high. There is no insulation in the floor above the crawl space. Anyone have any recommendations to insulate it.

The floor is a dirt floor.

The simplest means is to staple wrapped fiberglass batts into the floor joist from the crawl space.

The wrapping takes care of 'vapor barrier' issues.

You should then address the dirt floor by installing at least 2 layers of 6 mil polyethylene plastic construction sheating placed directly over the dirt floor. Layers hould be perpendicular to onve another and all seams taped.

You might also consider adding 4" of concrete on top of the crawl space to as a 'rat slab' to keep vermin out and to prevent radon gas from entering your living space.

my fathers house has fiberglass in in the joists or i should say had. after about 5 years the moisture in the crawl space started to cause it to decay. he has started tearing it out and replacing it with foam on the walls. he had plastic down but high ground water caused it to always be moist. just a point of information.

any suggestions on how to decide whether insulation in the floor joists is a good idea or not?

How would you know if there is too much moisture in the crawlspace that would cause rotting???
