Insulation on ground under open deck?

Jeffery Lindholm's picture

The house we bought has pink fiberglass insulation on the ground under the front deck. All the area under the deck seems to have a layer of pink insulation lying right on the open ground. Some of it's even buried under a light layer of dirt. This is a deck that's about 2 feet or so off the ground, with open spaces of 1/2 between the slats of the deck. The underside of the deck's not insulated; the insulation is lying on the ground.

Any reason why someone would do that? We're in Vermont, in case climate comes into it. It seems to have been there for a long while? Does it keep animals or wasps or something from digging holes or nesting under the deck?

I started to crawl under there and dig it out, but there's not a lot of space, there are some nails down in the dirt, and there's mold (I guess) on the fiberglass I pulled up that messed with allergies and made it hard to breathe.

So, what's up with this?

I'm gonna guess that there's something under there they didn't want to freeze.  Something like a cistern, or shallow water or drain pipes.
