I was starting to think about winterizing my home as the cool fall nights are approaching our Chicago area home and I came across a tip, that I used when my children were in school and forgot about.
Everyone knows we need to insulate windows and doors to make sure the cold outside air stays out side but we forget light switches and plugs.

Take the plates off light switches and plugs on outside walls and insulate them. They can be insulated with Styrofoam that you throw away from meat trays, easy to cut and fit behind the wall plate.

I have saved and washed the Styrofoam from my meat trays and I am ready to do the project this weekend. Give it a try and let me know what you think. It really is simple and saves energy and the earth by not throwing away Styrofoam that will not decay in the landfills.
