Attics

For your Attics we Blow an R-50 about 19 – 20 inches in our new construction homes. In residential attics we will bring existing insulation to an R-50. We use Blown in Fiberglass. We do not use cellulose.

Heating and cooling costs account for up to 50-70 percent of the energy used in an average home. This means that losing your home’s hot or cold air makes for a huge energy waste. Taking steps to prevent this loss is very important when thinking of ways to make your home more green. Any area where you can prevent wasting energy is always an important area to focus on.

Exterior Walls

Option #1 Blown in Fiberglass R-23

In my opinion this option is the best insulation for your money. It provides the highest R-Value possible in typical sidewall applications. When installed at recommended density levels, it yields an R-15 in 2"x 4" construction and an R-23 in 2" x 6" construction. This option offers a custom-fit seamless thermal blanket and outstanding thermal performance in irregular-shaped cavities and around obstructions.

Tests show that even a small gap in an insulated cavity can cause a substantial increase in heating or cooling costs. This option makes it easier for installers to provide a superior insulation job with no voids around wires, electrical boxes and pipes. And odd-sized framing assemblies are no problem. With this option there’s no cutting or fitting. The absence of voids means you’re assured of full R-Value for a superior finished job and exceptional thermal efficiency.

Option #2 Fiberglass Batts

Sustainable batt Insulation brings you long-lasting comfort through thermal performance, reduced noise levels and exceeds California’s strict Indoor Air Quality Requirements. It will last for the life of the building as it won’t settle, accumulate moisture or lose its R-value over time.

This product is easier to install and less expensive. It is a more budget friendly option. The R value is not as good as Blown in fiberglass or the poly urethane but is very effective when installed by professionals.

Option #3 Polyurethane Spray Foam

Spray-foam insulation has become a weapon of choice for many builders and homeowners trying to build tight, energy efficient houses. It fills tiny cracks in walls and roofs to form an effective air seal. The high R-values of closed-cell foam pack a lot of punch in a small space, and closed-cell versions can block the movement of moisture into wall and roof cavities. Expensive as it may be, it's at the top of its class.

For every inch of foam you get about a 6.5 R-value. So in a 2x6 wall you could expect to yield a thermal R value of about 36 points. Utility bills will be very, very low. Even just one and a quarter inch of polyurethane sprayed properly in the wall of a house will prevent more heat loss than all the fiber insulation that can be crammed in the walls. So imagine what 5.5 inches would accomplish. Not only does the polyurethane provide better insulation, it provides the house with significant additional strength. This application is labor intensive and is a very, very expensive chemical. However I believe this product does very little for noise reduction and I mean very little. A lot of contractors will use it in the Rim joists only.
