I've been looking at and posting about the things that companies like Cleanspace do for the crawlspace under houses. I want to get soe of your opinions on what I plan to do to my crawlspace. I have a sloped lot, so my crawlspace goes fro about 6ft. in the fron to about 2.5ft at the back of the house. The plastic under the house is in bad shape and I have a lot of areas of exposed dirt. I want to put down a new layer of 6mil plastic. I thought about the whole "sealed space" idea, but after talking to some of you I have decided against it. I just want the underneath area of my house to look neat and clean as possible. So...
Here are a few pics of under my house, and I have some questions. You can see that the builder sprayed the cinder block with some type of "loose pack" insulation. I'm not real fond of this stuff. I think it attracts and holds moisture. Plus, it's just plain messy. I would like to tear that stuff off of the walls and glue up some foam board in its place. Then I though I could attach the new plastic to the foam board about 4" from the top, run the plastic down the foam board and across the floor.
Does this sound like a good plan?
Also, notice that I have open joists. I've heard that putting insulation in between them is a bad idea nowadays. Any thoughts?
Thanks in advance for your input.
