Why Insulate Your House?
Heating and cooling account for 50 to 70% of the energy used in the average American home. Inadequate insulation and air leakage are leading causes of energy waste in most homes.
» Insulation saves money and our nation’s limited energy resources.
» Insulation makes your house more comfortable by helping to maintain a uniform temperature throughout the house.
» Insulation makes walls, ceilings, and floors warmer in the winter and cooler in the summer.
Heat flows naturally from a warmer to a cooler space. In winter, the heat moves directly from all heated living spaces to the outdoors and to adjacent unheated attics, garages, and basements – wherever there is a difference in temperature. During the summer, heat moves from outdoors to the house interior. To maintain comfort, the heat lost in winter must be replaced by your heating system and the heat gained in summer must be removed by your air conditioner.
Insulating ceilings, walls, and floors decreases the heating or cooling needed by providing an effective resistance to the flow of heat.
