How Insulation Works
The more heat flow resistance your insulation provides, the lower your heating and cooling costs.
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 indirectly through interior ceilings, walls, and floors—wherever there is a difference in temperature. During the cooling season, heat flows from the outdoors to the interior of a house.
To maintain comfort, the heat lost in the winter must be replaced by your heating system and the heat gained in the summer must be removed by your cooling system. Properly insulating your home will decrease this heat flow by providing an effective resistance to the flow of heat. An insulation’s resistance to heat flow is measured or rated in terms of its thermal resistance or R-value.
Unless your home was specially constructed for energy efficiency, you can usually reduce your energy bills by adding more insulation. Many older homes have less insulation than homes built today, but adding insulation to a newer home may also pay for itself within a few year
Cooler in the Summer and Warmer in the Winter!!!
The attic is by far the most important area of your home to have insulated. All too often homeowners believe they have adequate insulation in their attic when in fact they only have a small fraction of what they should have. Current Energy Star Guide lines suggest that most Los Angeles area homes should insulate the attic toR-38 level. If your heating and cooling bills are unreasonably high or you are suffering with an uncomfortable or drafty home. Check your attic insulation!
Attic insulation works both during the summer and during the winter. In summer it blocks heat from coming into the home and in winter it holds heat from rising out. The result is a more comfortable home with lower energy bills year-round.
Most homes built before 1972 do not have insulation in the walls!!!
Properly insulated exterior walls in your house will not only increase comfort but also help you save on heating and cooling costs. For energy savings, you can add insulation to your walls in an existing house. Wall insulation also can help quiet outside noises such as traffic and airport noise…
