insulating an exterior porch

dian57September 21, 2010

Our 1947 cape cod has a side porch off the kitchen that was enclosed and converted to a pantry. We added a small electric baseboard but want to insulate under the floor, which is currently accessible.

We are in zone 5 with frigid upstate NY winters.

If we put fiberglass batting between the floor joists, should we staple plastic sheeting over it? We plan on caulking where the floor meets the house for drafts and critter blocking.

When all this gets done we're installing small-square vinyl lattice dug into the ground to prevent the previous tenant (a mangy coyote) from moving back in. This why I want to do this once and do it correctly.

Thanks for your reply.

The plastic is a vapor barrier. Vapor barriers should face towards the warm side. In your climate, that is the house. If you are using fiberglass, you will be better off just getting the faced kind and putting the face up against the bottom the floor. The sell little hangers that will keep the batting in place.

Thanks, Bill. I guess when I pick up the insulation I can ask about the hangers. They'll keep things intact, right? Once we put that lattice up, there are no plans of returning unless some disaster strikes under there.
