Hi all,

We just had our first bout with cold weather here in SE VA and it may be old age on my part but it seems like my floors are colder than they were last year! My house is a 1942 Cape Cod on a crawl space. I've been under the house and there is insulation between the floor joists but it was in sad shape. Should I install new fiberglass batt insulation, foam or what? I'd also like to know if I should block off the foundation vents in the winter. I *hate* for my feet to be cold!

The other insulation question I have is, what is the general cost for injected foam (closed cell?) insulation into the exterior walls? If it helps any, my house is 1500sf roughly. Thanks for any help or information!
