If your home is adequately insulated, the average temperature should be easily maintained. It will keep the heat in during the colder months and keep the house cool during the hot summer months. Proper insulation can even remove the need for an air-conditioning system in your home. These systems can use a fair amount of electricity and in some cases, can be noisy.
By ensuring good insulation in your home you can reduce your electricity bill when not using an air-conditioner. There are a variety of insulation materials available on the market, all of which function in a different way but to serve the same purpose- keeping your home temperature regulated.
