Use spray foam insulation to keep the cold out in your attic.
Spray foam insulation is used in buildings, docks, ships, roofs and aircraft wings. The main ingredient is polyurethane foam that expands after being sprayed onto a surface. Using a spray insulation for your attic will keep it warm during the winter and cool when the temperature starts to get hot. Spray foam is non-toxic and often carries a lifetime guarantee, making it a preferred insulation solution. However, this is a very labor intensive DIY task, and this must be considered before attempting to do this job yourself. Does this Spark an idea?
Instructions
1. Remove all items from the attic before spraying. Cover any items you cannot move with plastic sheets.
2. Practice on a test area before covering the entire attic with insulation. Get used to the power of the spray nozzle and how much pressure to apply. Also note that the foam expands to 100 times its initial volume, so plan accordingly.
3. Spray the foam evenly between the framing studs on the backside of the exterior sheathing. Allow it to expand and work its way into all gaps, form and set.
4. Shave away any foam that extends past the wall studs, using a handsaw blade, if you are going to be installing drywall. The insulation should be flush with the wall so that drywall can properly be installed on top.
