I have an 18 year old house that I've just recently purchased. The floors were incredibly cold, so I had a home energy audit performed, which revelaed that insulation (or lack of) was my source of heat loss. Now, after spending a fairly significant amount of money to spray foam the entire crawl space and bring the attic up to R50 values, the floors and home are still cold? What gives? Not really sure what my next steps should be. I'm very frustrated and certainly can't continue to spend frivolously. Any help or suggestions would be appreciated. **also note that I have 3 skylights, which are certainly a contributor, yet shouldn't be the only contributing factor.
