Insulating your house is one of the best decisions you can make. Insulation protects you from the elements and makes the home more energy efficient.
Home and attic insulation is essential to surviving a cold New England winter. Without insulation, you just have bare space inside your home’s walls and ceilings. When icy weather and cold wind is in the air, you need insulation. Insulation is the only thing protecting you from the elements, aside from the home’s walls and possibly vinyl siding if you have it. When you install blown-in or rolled insulation, you’re making a smart energy choice. It’s like wrapping a warm sweater around your home. Most of a home’s energy is lost through ceilings, walls and floors. That’s why it’s so important to insulate. 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.

Home and Attic Insulation:
- Saves money and our nation’s limited energy resources
- Makes your house more comfortable by maintaining a uniform temperature throughout the house
- Makes walls, ceilings, and floors warmer in the winter and cooler in the summer
How Insulation Works
Heat flows naturally from a warmer to a cooler space. In winter, the heat moves directly from all heated living spaces to the outdoors. Adjacent unheated attics, garages, and basements are a prime spot – 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. The heat gained in summer must be removed by your air conditioner. When you insulate ceilings, windows, walls, and floors, you decrease the heating or cooling needed. This is done by providing an effective resistance to the flow of heat. See the graph below for more information:
In addition to saving on your heating and air conditioning bills, you can also save money through the following methods as well:
If you install home or attic insulation, you may qualify for a rebate from your local energy company.
You may also be eligible for tax credits for installing energy efficient windows, doors and skylights as well.
The amount of energy you conserve will depend on several factors. Your local climate; the size, shape, and construction of your house; the living habits of your family; the type and efficiency of the heating and cooling systems; and the fuel you use. These can all be factors. Once the energy savings have paid for the installation cost, you save money as energy is conserved. Saving energy will be even more important as utility rates go up.
Batts, blankets, loose fill, and low-density foams all work by limiting air movement. These products may be better known as fiberglass, cellulose, polyicynene, and expanded polystyrene. The still air can insulate because it eliminates convection and has low conduction. Some foams, (such as polyisocyanurate, polyurethane, and extruded polystyrene), are filled with special gases that provide additional resistance to heat flow.
Reflective insulation works by reducing the amount of energy that travels in the form of radiation. Some forms of reflective insulation also divide a space up into small regions. This reduces air movement (or convection). Not to the same extent as batts, blankets, loose-fill, and foam though.
