Hey guys -
I've been doing some casual research over the past year or so about insulation. I have a house on a lake and as a result its very very humid for a good part of the year. Also, the house isn't terribly well insulation, and to add insult to injury, the only heat is electric baseboard heat. We're not there full time in the winters, but when we are we stay on the first floor and do our best to keep the heat low. Also, we drain the house and turn off the heat when we're not around during the week.
We experimented last winter with leaving the heat on in the kitchen and living room at 50 degrees. When we got the $400 electricity bill for the month, we decided that leaving the heat on wasn't an option.
SO. A lot of backstory I know, but I wanted to explain the situation. I would like to insulate the crawlspace beneath the house. Mostly because I want the floors to be warmer, and I want to reduce the drafts, and hopefully seal up a few holes down there as well where the spiders get in (wishful thinking I know).
I have an estimate from one contractor that goes as follows:
1. Spray foam walls with R10 sealed to vapor barrier on floor $3822
2. Fiberglass floor joist with R30 fiberglass insulation. $1592 (Not an option in my opinion)
3. Spray foam floor joist with R30 open cell foam. $4525
Based on this info alone, what do you guys think? I would estimate the crawlspace is 900sq ft.
Thank you for your thoughts
