Most houses are built with 2x4 framing covered with wall board or plaster. This leaves an empty space where the electrical wires and water pipes are hidden inside the walls. Things like water pipes, sewer pipes and electrical wiring pass through from floor to floor in these hidden spaces inside your walls.
Hollow interior walls can act like chimneys pulling warm air into the space between the walls and sending it up to your attic.
You really should crawl around in your attic to check and seal the tops of interior walls. Sealing around any pipes or wires that pass upward into the attic is a priority.
Being a lazy old man, I vote for the easy way and stop the air leaking into the walls.
We all have seen the flimsy foam rubber gaskets that are used to seal light switches and outlets. Most folks think that these are something to be used only on the exterior walls to stop air leaks to the great outdoors. Not so. You need them everywhere in the house. Install the gaskets on all outlets and light switches to help stop the loss of heated air up through your walls. Look for them at your favorite hardware or building supply store.
Plastic, child proof, safety plugs can be used to stop air leaks through unused electrical outlets. My wife goes around the house before our grandson comes to visit making sure all the safety plugs are in place.
When he arrives he knows this game and scoots around the house collecting safety plugs like he was on an Easter egg hunt. I did not think that a 14 month old had the finger strength to pull those plugs. Wrong again.
Keeping the warm air that you paid to heat inside the house is a good way to keep your heating bill down.
