Question from a reader:

Question: I've been trying to do some remodling of a older house I hope you can help. I have some crawl spaces underneath house in order to get underneath for any kind of work that has to be done. Is there anything that can be used to put on bottom of floors to help keep the inside floors warmer. I've heard about spray on insulation or regular insulation but not sure about these.

Any ideas?

There is insulation that comes in the form of thick styrofoam sheets. Given the tight space that you are working in and the "mess factor" this would probably be a good way to go. To get a smooth even cut, you could use an electric knife to cut it to the size you need. We've used it in a root cellar located under our kitchen floor.
