Attic Insulation

Diagram of heat loss during Winter

Did you know that most homes in the United States are improperly insulated or under insulated for their homes climate region?  In Southern California especially, the scorching hot summers bring with it high cooling bills and when it cools down in the winter the heating bill takes over. On top of that energy prices are at an all time high and increasing steadily.

A United States Department of Energy study shows that heating and cooling costs account for 50 to 70% of the energy used in the average American home. With the extreme climate in our region these numbers may be even higher.

Attic insulation works by limiting the movement of air in your attic, keeping the warm air inside your home and not letting it escape through the roof in the winter and blocking heat from entering the home during the summer. As shown on the diagram to the left, air is pulled into your home through cracks in doors, windows, electrical outlets and vents. When the air in the attic begins to cool, warm air is pulled up from the living area into the attic to balance the temperature. This works the opposite way in the summer, the sun warms up the air in the attic and radiates down into the rest of the home. Most air conditioning units cant keep up at the rate that the heat is coming in from above and you are left with a home that doesn’t stay as cool as you would like and a rather large bill at the end of the month.

Standard fiberglass batted insulation isn’t as effective as other solutions. Fiberglass ‘bats’ are pre-cut so when put between framing it is meant to be a perfect fit, however, not every house is perfect and there will be gaps if the spaces are too large or too small. Bats also can’t reach some of the small spots where the need for insulation is most critical. Fiberglass insulation isn’t very dense and it takes almost 12” to reach a level of R-30.

With improved cellulose insulation in your attic you will notice the difference immediately. Cellulose has magnificent insulation characteristics and is installed by being ‘blown-in’ to the attic. Because of its loose form, it can find its way into small cracks, gaps and even into areas not accessible by crawling in the attic.

Cellulose makes a great soundproofing material and may homeowners with cellulose insulation have reported less noise in their home. Cellulose is meant to last a lifetime as it is designed never to settle or lose any of its insulating qualities and is treated with products to deter infestation of rodents and insects.
