Will insulating the crawl space help reduce cooling costs?
I'm thinking about insulating my crawl space but not sure it will be worth it.
I have a 100 year old, 2000 sq. ft house in new orleans that is about 4 feet off the ground. The floor is in excellent condition, but it's the hardwood and that's it. No subfloor, so winter is chilly. I got an estimate of $3300 for closed cell foam. But, considering that our winters are pretty short and mild, I want the investment to help with cooling costs as well. I have uninsulated walls and cellulose in the attic.
If anyone has an experience adding crawl space insulation, I'd love to hear what impact it has on your cooling costs. Everything I hear/see/read points to saving on heating costs, not cooling.
Many thanks in advance for your thoughts.
