Insulating attic and porch.

The purpose of insulation is not to keep the attic warm but to keep the house warm or cool. Install batting between the attic s floor joists. Plan to pull up the flooring and layer new insulation on top of the old. The batting material must be faced and.

You actually want the attic to stay relatively close to the outside temperature to prevent ice problems in the winter or overheating in the summer. If not then don t bother. But if the floor is covered in plywood you can t stuff enough insulation beneath it to do the job sufficiently not even in warm climates. The important thing is that the ceiling above your living space is insulated because that s the area you heat cool.

The insulation should fit snugly to prevent air from getting through. Large foam insulation sheets can be nailed directly against the floor above or held in place by chicken wire or other metal elements with the facing against the underfloor. Insulating attic floors unfinished or uninsulated attics need a layer of protection against air migration. If you can crawl under your porch insulate from below by nailing plywood boards to cover any openings.

Because the simplest and cheapest way to insulate an attic is to add material to the floor. Your porch being open on one side doesn t really need to be insulated at all. Not sure where exactly to insulate.
