Seal your Attic to Save Money and Energy
Attics are notorious for losing up to 30 percent of conditioned air. Common areas of leakage in attics include behind the knee walls, exterior wall plates, attic hatch, wiring holes and lights, plumbing pipes and furnace flues. By taking the time to inspect for leaks and seal your attic, you can save money and save energy losses.
How and Where to Seal the Attic Spaces
- Sealing the Perimeter: Air sealing the wall plate around the perimeter of an attic prevents air from escaping around the outer edges of the house. It’s a cramped space to work within, but it can be done. Start in the corner and work on one section at a time. Move the insulation and lay some plywood down for a secure work platform. Crawl under the eaves and use a sealing gun to apply the seal. Some products are foam but dry quickly.
- Top Plates and Electrical Wires: Locate the top plates on the interior walls. Remove the insulation and squirt some sealant between the framing and the drywall. There will likely be some wiring projecting through the plate. Just stick the sealant tube down in the hole and press the trigger. Once the application is no longer sticky, you can put the insulation back into place.
- Air Sealing Ceiling Light Boxes: Most attics have a light in the center ceiling of the room. The hole surrounding the light fixture should be sealed. Be sure to seal around the light box where it reaches the drywall and the wiring holes on the sides and top of the box.
- Air Sealing Attic Chases and Plumbing Pipes: Plumbing pipes enter the attic through an opening called a plumbing chase. Typically, these pipes have large holes cut around them. If the hole is large, you’ll need to use a foam insulation board or a piece of drywall to cover the hole. Once the hole is covered, just apply the seal with a sealing gun.
- Sealing the Furnace Flue: Size up the approximate diameter of the flue. To be on the safe size, cut a circled piece of sheet metal just a little bigger but not too big. It needs to fit between the ceiling joists. Cut the metal circle in half and place one half on the side of the flue. Place the other half on the other side of the flue and seal it off with a high temperature caulking or sealant.
