Overview and benefits

Homes often either lack the proper amount of insulation or they do not have any at all. This is especially true of older New England homes, which typically don't have adequate insulation levels to keep your home at a comfortable temperature. Since your attic and exterior walls take up the largest surface area of your home, they can be your greatest areas of heat loss in the winter and cooling loss in the summer.

A well-insulated home can increase overall comfort while reducing energy usage and lowering utility costs. Insulation is added between walls and in attics to ensure that the conditioned air from your heating or cooling system stays within the home. Proper insulation and air sealing work together to create an effective thermal envelope, the barrier that keeps heat inside during the winter and outside during the summer.

Increased insulation also comes with additional benefits, such as reducing outside noise, decreasing the amount of pollen and dust that enters your home, and increasing humidity control.
