Spray on insulation under house on piers
My house is on piers during winter floor gets really cold. I heard of spray on insulation. Has anyone tried it? Does it work? Can you recommend someone to have it installed?

Get you some carpet.
Heat rises. In respect to your homes thermal envelope, your home looses heat primarily thru your roof, then your walls and last your floor. Don't like carpet, look into heated floors.

Have not tried it, but it does work. If you choose to do spray foam you need to be sure to do an open cell insulation. Closed cell will trap moisture and could cause wood rot. The R value from open cell spray foam insulation is not that high but you will see a noticeable difference in drafts, especially where air migrates through walls and electric outlets.
Not sure if its cost effective for this scenario though. If its just for comfort, go for it. If your reasoning is financial in nature, you may need to rethink it.
