    I started insulating the floor joists to our house today and found a whole new respect for everyone that does that sorta work for a living. I'm 6 2" and crawling around in the crawl space is def not my ideal afternoon. Hopefully the work will pay off and help keep the floors a little warmer. we have a large kitchen that is tile and when the weather gets cold that floor is like walking on ice. we are planning on putting hardwood in next yr so i figured with the "Bush" era taxes coming to an end i better do it so i can file it on my taxes this yr.

    Has anyone else done this? and if so did it really make that big of a diff? guess i shoulda posted this b4 buying nearly 30 rolls of insulation....:head:

    I used to Insulate houses for a living a long time ago.And your right,Insulating under the floor was the worst part of the job.I hated it,A mixture of dirt,cobwebs and fiberglass in your eyes is not a good way to make a living!

    And it should help your cold floor problem,Your heating bill too.:up:

    Be sure and install the paper side up,towards the living space.And a hammer stapler would help if you can find one,Its easier in tight spots.

    I lease a lodge in Kansas and the floor was like ice. I sprayed in insulation under the whole floor. You are very right, it was a pain. I was eating the foam insulation and got abunch in my eyes. In the end it made a very big difference.

    Well, it was kinda like a mixture of dog dukie and stale urine. Needless to say it aint something I want to try again.

    It'll be fine ha.. We just spent two weeks under a house tryin to level a fallen floor, and moving 80lb concrete blocks, 5x5 posts and other junk to do the job sure is a workout!

    I would much rather help you hang insulation! :fit:

    If you can get ahold of a hand stapler(the push against and squeeze type) the tights spot wont be as bad. Hard to swing a stanley hammer stapler in tight spots.

    Hope you do not have a water problem under your house, The insulation can get wet by condensation and once it does it will not dry out and will cause your floorjoist to rot .

    NWA house is insulated to the T like in walls that don't need it at ALL, and I've wondered about doing the floors but have been told the the crawl space provides all the airspace I need and the cost savings aren't there. I only have wood heat, do I really lose alot of heat thru the floor?
