In the average home Heating and Cooling contributes for 50 to 70% of the energy used. Lack of insulation and high air leakage are major causes of energy waste in most homes.
Insulation, makes your house more comfortable by helping to maintain a uniform temperature throughout the house and makes walls, ceilings, and floors warmer in the winter and cooler in the summer.
The amount of energy you conserve will depend on several factors:
Once the energy savings have paid for the installation cost, energy conserved is money saved - and saving energy will be even more important as utility rates go up.
Weatherization Services LLC will help you understand what different types of insulation are available, how insulation works, and how much insulation makes sense for your home. There are many other things you can do to conserve energy in your home as well. The Department of Energy offers many web sites(http://energy.gov/) to help you save energy by sealing air leaks, selecting more energy-efficient appliances, etc.
There are different types of insulation available. Some work as better air sealers and insulators then others. However, all insulation, whether it is fiberglass, cellulose, polyicynene, and expanded polystyrene all work by limiting air movement. The still air is an effective insulator because it eliminates convection and has low conduction. Some foam, such as polyisocyanurate, polyurethane, and extruded polystyrene, provide additional resistance to heat flow.
Naturally, heat flows from a warmer to a cooler space. The heat moves directly from all heated living spaces to the adjacent unheated attics, walls, garages, and basements, in winter - wherever there is a difference in temperature. In the summer, heat moves from outdoors to the house interior, which is the opposite of winter time. 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 and air sealing attics, walls, floors, and basements decreases heating or cooling needed by providing an effective resistance to the heat flow.
