If it's enclosed on the bottom, you might also consider putting the
poly on the ground and weighting it down with pea-stone. That'll keep
the ground mosture out but won't do anything for the moisture in the
air.

Hello all,
I have a closed in front porch and it has a crawl
space underneath. I want to insulate it for the winter.
It has exposed floor joists and I can see the subfloor.
My question is what type of insulation is best for this?
Also what is the correct way to install it?
I live in NJ where there is plenty of heat and humidity.
And could be very cold in winter. Thanks
If there is no chance of it getting wet just use fiberglass batts and poly
for a vapour barrier, otherwise look for a rigid type insulation.
