Attic Insulation

High utility bills due to the lack of energy efficiency, is one of the most significant concerns to home owners here in the Dallas – Fort Worth Metroplex. Traditional houses are built with the attic floor as the air barrier and the ceiling as the thermal barrier. The attic floor is typically lined with fiberglass insulation or cellulose insulation that is either loosely laid in or blown in forming the attic insulation. A much more energy efficient solution would be completely removing the old attic insulation and installing spray foam insulation instead.

How is Spray Foam Insulation Installed in the Attic?

The spray foam insulation is strategically sprayed in the attic covering the entire roof deck, roof air vents, soffits and sometimes more depending on specific applications. This seal allows your attic to now be a conditioned space, raising the air barrier from the attic floor to the bottom of the roof deck and in addition requiring a new thermal barrier to be added in most cases.

In very rare cases (and not recommended by Shield for safety reasons) an ignition barrier is allowed in place of a thermal barrier. Since your attic is now a conditioned space, Shield will also recommend adding one or more HVAC vents in the attic. (Note: Air from your HVAC system that goes into your attic is not wasted as it is now inside your homes’ building envelope, which is basically like another room in your home.)

What are the Benefits of Spray Foam Attic Insulation?

It Helps Keep What You Need, In

Spray foam insulation is designed to create a nearly impenetrable air barrier at your roof deck. With standard insulation, air leakage is one of the most vital issues you face. In simple terms, the extreme hot or cold air from the attic is seeping back into your house because the standard insulation is allowing too much to come through. In addition your air ducts are flowing through those extreme attic temperatures diminishing the hot or cold air your HVAC system just produced. Meaning your HVAC system is having to work harder than it should to maintain the temperature of your home. Spray foam in the attic when applied as we just mentioned not only stops the leaking air it also allows your duct work to flow through temperatures that are within a few degrees of the inside of your home.

It Helps Keep What You Don’t Need, Out

The air barrier created by spray foam insulation not only keeps the air inside but it also helps keep unwanted guests out. Small rodents are known, especially during the colder months, to take lodging in attics. Since spray foam fills every possible crack or opening in your roof deck, this makes it much harder for even smaller rodents to find a way inside. Also, Spray foam is made from an organic chemical that does not serve as a food source for pests or rodents trying to get inside.

It Helps Keep Money In Your Pocket

The EPA’s Energy Star Program estimates that you can save up to 20% on your monthly energy bills by sealing air leaks and upgrading your insulation although we have seen savings much higher for some home owners.  The weather in North Texas can move from extreme heat to intense cold throughout the year. HVAC costs are among the highest expenses a home owner will face. With a weak air barrier, the controlled atmosphere slowly leaks in causing the HVAC system to work even harder. By raising the barrier to the roof deck and forming a substantial air barrier, you extend the conditioned area into the attic. This keeps the internal temperature from drastically changing and allows the HVAC system to operate more efficiently thus typically resulting in much lower utility costs.
