16" is the way to go!

A client reached out about their crawlspace flooding and the original insulation had to be removed before mold started to grow. I purchased 2 rolls of the 16" to wrap the main trunk line and it was such a time and energy and life saver! I highly recommend using this for anyone going forward. And the price just can't be beat either.
