How to Insulate Above a Foyer

If your foyer is very cold in the winter and hot in the summer, insulation may be the solution. You will need access to the attic space above the foyer, which may not be the most comfortable environment to work in, but it will be worth it when you are finished. Besides adding insulation, also check for leaks from interior walls to the foyer area. Sealing these leaks can also help prevent heating or cooling loss in that area of the home.

Instructions

- 1
  Inspect the attic area above the foyer. Examine the existing insulation if there is any present. Also look to see if there are openings through the walls that air can easily get to. This may be as simple as sealing drywall seams that aren't covered by insulation. Look for soffit vents where the attic meets the exterior wall and roof line. These vents have to be kept open so the house can breathe. If you already have baffles above the vents, you do not need to add more.

  Put on a dust mask and work gloves. Bring the insulation batts up into the attic. Install baffles above the soffit vents if none is in place. Soffit vents attach to the roof sheathing with staples.
- 3
  Lay the insulation. If there is no insulation above the foyer to begin with, lay the insulation between the joists. Add another layer of insulation above the joist insulation. This application works for newly installed joist insulation as well as over existing insulation. Lay rows of batts perpendicular to the joists and make sure the edges touch. Trim the insulation to fit with a utility knife.
