Insulating the bottom floor

Thanks for viewing this message. I would like to put insulation under the floor of my home. I have approx. 18 to 24 inches of clearance from the ground to the floor joist. The joist are on 24 inch centers. The perimeter of my home is cinder block with a coating of motar spread over the outside with several vents placed in the block. I have two access points in which I can get under the house. What is the best way to go about this? Any and all help will be appreciated

If you use Fiberglass. I would reccommend that you go with 10" R-30. Push it up between the floor joists with the paper side toward the underside of the floor above (paper towards warm side) To hold it in place after you can either buy tiger teeth which are heavy gauge wire that is slightly larger than the width of your floor truss spacing. These are placed under the insualtion every two feet. Another method to hold it in place is to staple plastic banding across the underside of the joists.

Good Luck
