Bio:If you're looking for a cheap and easy way to save energy in your home, one of the best Do-It-Yourself home improvements is to install foam electrical outlet gaskets to seal your sockets. If you happen to stand by your outlet sockets and switch plates on a windy day during the winter, have you ever felt cold air blowing from these places? The purpose of foam gaskets is to seal and insulate the wall cavities behind all outlet and switch plates, creating a barrier from the living space. If an energy audit firm conducts what is called a "blower door test," you will be amazed to find a generous amount of outside air blowing out from all wall plates. A blower door test depressurizes the home to expose air entering the home from the outside. In other words, it turns the house into a giant vacuum chamber. Some people will tell you that you only need to insulate outlets and switches on outside walls. Conducting a blower door test confirms that ALL switch and outlet receptacles (including inside walls) are leaky and need to be sealed since electrical wires run across walls allowing outside air to enter the inner-wall cavities. Inner-wall cavities also contain pipes, introducing outside air from your crawlspace, basement or attic. All of these wall penetrations contribute to a heating and cooling loss by as much as 20%. This is what makes the inner wall cavities subject to cold air even in a well insulated home.
