ELECTRICAL OUTLETS

You have holes all over your house; they just may be hiding under electrical outlet covers.

  1. Turn off the main electrical switch for the area of the home you will be air sealing.
  2. Use a screwdriver to remove outlet cover plates on perimeter walls.
  3. Homes have holes cut in the drywall or plaster for electrical outlets. Check for gaps between the wall and the metal or plastic box that houses the electrical socket.
  4. Fill the gap around the perimeter of the electrical box. Do not use GREAT STUFF™ Insulating Foam Sealant anywhere inside the box.
  5. Allow the foam to cure completely (usually takes 8 hours). Trim excess foam with a serrated blade so that the foam is flush with the wall.
  6. For an airtight electrical outlet seal, also utilize a foam gasket. Foam gaskets are readily available at hardware stores. Simply place the gasket over the front of the outlet.
  7. Replace outlet covers. Note: GREAT STUFF™ Insulating Foam Sealants are combustible, so it's very important that all electrical switches are turned off before starting your project. Also, never apply foam to exposed wire or inside an electrical box. Be sure that wires have a protective covering before applying.

Main Electrical Panel

It's the hub of all electricity in the house and a large distributor of unwanted airflow.

  1. Be sure to turn off the main electrical switch.
  2. Stand in front of the main electrical panel and trace, starting at the top of the panel, the covered wires until the main electrical supply enters the main floor of the house. Be sure that wiring is run through a pipe or a protective covering before applying foam.
  3. Air seal around the entry hole to the main floor with GREAT STUFF™ Fireblock Insulating Foam Sealant.

Note: GREAT STUFF™ Insulating Foam Sealants are combustible, so it's very important that all electrical switches are turned off before starting your project. Also, never apply foam to exposed wire or inside an electrical box. Be sure that wires have a protective covering before applying.
