Your windows can be the bane of your existence. During the summer, the heat will come in almost unimpeded and in the winter, the cold will do the same thing. You can fix this! You can create your own plastic window covers or simply use blankets or other items in your house to cover them up. It won’t let as much sunlight in but it will help keep the heat and cold out. These can help save you money on your electricity bill and gas bill because your heating and cooling won’t have to work so hard to keep your house at a comfortable temperature. Another good idea is the draft stopper.
