Insulating your attic is crucial for keeping your living space comfortable and decreasing your energy bills. There are many things you need to know about installing insulation in your attic.

Proper installation is necessary for your attic insulation to be effective. Your comfort and utility bills will be negatively impacted if the attic insulation is not installed correctly.

Ensure that your attic is properly ventilated before installing insulation to maintain the right levels of moisture and reduce the risk for mold growth. An attic ventilation system can help prevent moisture and potential mold because it creates a continuous upward air flow.

Loose-fill insulation (also known as blown-in insulation) is typically used in open attics. Loose-fill insulation creates a complete thermal blanket to decrease the transfer of heat. Blown-in insulation also fills corners in the attic and makes your existing home more comfortable and energy efficient.

Air leaks should be sealed before adding insulation for additional energy efficiency. Sealing air leaks will plug penetration points to prevent air transfer which helps with energy savings.

Installing spray foam insulation in your attic seals air leaks and adds R-value. Spray foam is applied along the roofline to seal the very top of your home and help prevent temperature fluctuation.

Contact a qualified insulation contractor to install spray foam insulation in your attic. A professional contractor will assist to make sure you have proper ventilation in your attic and the right R-value.

The thickness of spray foam insulation is determined by multiple factors. Insulation is rated by its R-value which measures the resistance to heat flow. A higher R-value indicates higher thermal resistance. The R-value is apparent for cellulose, fiberglass or mineral wool insulation. But the R-value of spray foam insulation depends on the type of spray foam that is installed.

The R-value of spray foam insulation is different. Spray foam insulation R-value is contingent on the type of spray foam insulation being applied. Spray foam insulation is available in open cell and closed cell.

The R-value of open cell spray foam is about 3.5 per inch, although the R-value can be different depending on the product. Open cell spray foam has a low density and is many times applied in interior walls and areas that are hard to reach in a home.

The R-value of closed cell spray foam ranges from 5.0 to 7.0 per inch, although the R-value can be different depending on the product. Closed cell spray foam is denser than open cell spray foam and is often used in areas like basement box sills where it helps prevent moisture from entering the home.

So, to answer the question “How thick should spray foam insulation be?” the answer depends on certain factors. The U.S. Department of Energy recommends insulation levels relative to the climate zone and part of the structure being insulated. It is also essential to examine the degree of moisture permeability that is needed. These factors determine whether open cell or closed cell spray foam insulation should be installed.

Consult with a professional insulation contractor to ensure that your home has the correct amount of insulation. At Southland Insulators we have the expertise and training to advise you on the right insulation for your home.

Saving on energy bills and maintaining a comfortable home or business starts with insulation. Insulation resists heat flow, so when heat flow is decreased your home’s interior temperature stays more comfortable and your utility bills are lower.

Heat flows from warmer to cooler areas until the temperature equalizes. So warm air attempts to leave a home or building in the winter and hot air attempts to come into a home or building during summer months. This causes your HVAC system to work more to sustain the ambient indoor temperature resulting in higher energy bills.

Proper insulation provides an effective thermal barrier to decrease heat flow, lower energy costs and maintain a more comfortable living space. If you are interested in installing insulation in a new home or building or are interested in upgrading existing insulation, contact us for an estimate.
