Insulating Your Home for Energy Efficiency and Comfort - Why Insulate? Properly insulating your home will help reduce your heating and cooling costs and make your home more comfortable. Insulation is a smart investment because it provides year-round comfort and savings. Heat flows naturally from a warmer to a cooler space. In the winter, this heat flow moves directly from all heated living spaces to adjacent unheated attics, garages, basements, and even to the outdoors. Heat flow can also move through interior ceilings, walls, and floors—wherever there is a difference in temperature. Insulating keeps heat where you want it to stay. [more...]
