Crawl space and insulation..


I have a crawl space that is approx 15x20. Currently the insulation is exposed in the above beams and is starting to hang down. Looks like cotton candy..for lack of better terms...and I wanted to replace it. I was wondering if there was a way to keep that from happening. The space is not heated of course and the is plenty of ventilation. I was thinking a thick plastic staples up to the beams to hold it there and possibly sealing off the above cavities...and proper textbook way to insulate in between the beams and keeping it from having sagging fibers...thanks in advance for the help.....

Crawl space and insulation..


Those are already in place. That how the insulation is being held up. The insulation doesn't have waves in it its just the fibers are stringy now and I almost looks like someone was pulling cotton candy. Sorry only way to describe it...I read 3mil plastic sheeting to keep out moisture..maybe the fluctuation in humidity is doing it. What really wanna know is what is the best way to insulate a crawl space using fiberglass for the joists....the rods hold it in place but what else....Thx again

ouch. tear that crap out and replace it with Roxul and rigid foam on the bottoms of the floor joists. tape the edges/ends of the foam and install a 6 or 8 mil visqueen vapor barrier on the floor. search here; lots of threads on insulating crawl spaces.

thinking of tiger teeth ? you could always staple mesh fabric to hold the f/g in place,,, 6mil's popular 'cause apron/vest stores sell it cheap & those stores are EVERYWHERE IF you want a decent vapor barrier that will stand up to crawling/duckwalking/scootching w/o ripping/tearing/shifting, find something substantial,,,we use stego (no financial interest),,, might be overkill but no client has yet complained when we demonstrate its superiority over 6mil stuff

stego wrap is 10x what 6 mil visqueen is; very tough stuff. it costs much more than visqueen, and for a reason. i'd use it in a heartbeat.

Here is a link about venting crawlspaces. Might make you reconsider your plan.
