Here are some steps for insulating crawlspaces without pipes and ducts:

Step 1: Press the insulation between the floor joists above your head starting at one end and working out until the cavity is filled. Insulation with a vapor retarder should be used, with the vapor retarder facing up towards the heated area of the home. The insulation should be installed up against the subfloor. The insulation will stay temporarily in place.

Step 2: Once the insulation is in place, hold it in position with either insulation supports, or if the insulation fills the joist cavity, staple chicken wire to the bottom of the joists OR lace wire back and forth around nails in the bottom of the joists.

Step 3: To prevent loss of heat, check your work. Make sure the ends of the batts fit snugly up against the band joists, and the batt itself fits up against the bottom of the subfloor.

Step 4: After you’ve insulated the floor above, completely cover the ground within the crawlspace with polyethylene sheeting and secure it in place with rocks or boards.

Hope it works for You!
