I have powder post beetles which will require removal of the R 19 rolled insulation in my crawl space. Hse is 23 yrs old, passive solar. I will need to have moisture barrier put down. I have been offered an option of sealing off the walls with 10 mil moisture barrier, insulating and not replacing rolled insulation, but, I am worried that future work like replacing furnace/ducts, etc. might fracture the plastic. How can I maximize geothermal assist, meet code and solve my problem?

Elizabeth,

In my opinion, the best option would be to insulate the floor (ground) of the crawlspace and the foundation walls essentially making this area conditioned space.

The best insulation for this...
