Why High R-Value Attic Insulation is Important for Energy Efficiency

If you live in an area where temperatures fall well below freezing during the winter months like we do in Maryland and Virginia, you might have trouble keeping your home warm. Several culprits can contribute – single pane windows, poorly sealed windows and doors, and even vaulted ceilings play a factor. Another big contributor is your home’s attic insulation.

Heat Rises

Heat Loss Through AtticThe laws of physics tell us that heat rises. It stands to reason then that any heat generated through the vents in your floor will make its way to your ceilings. If your home is 2 or more stories, you know that your upper level is warmer than your lower levels. Eventually that heat makes its way to your attic, and if your attic insulation is lacking, the heat escapes through your roof.

Many homes come with standard roll-out insulation in the attic. That’s should be sufficient, right? To know for sure, we need to know about R-Value.

What is R-Value for Insulation?

R-Value is a measurement given to insulation. The R in R-Value means Resistance to heat flow. The higher the R-Value, the more resistance. Standard roll-out insulation with thicknesses of between 3.5- to 14-inches have an R-Value between R-11 and R-19. Blown-in insulation offers higher R-Values depending on how many inches are installed. 

How Much Insulation Do I Need?

The Department of Energy (DOE) published recommended R-Value ratings for various climate zones throughout the United States. Below is their published chart. Homes in Maryland and Virginia fall into Zone 4, with recommended R-Value ratings between R-38 and R-60.

Measuring InsulationAt S&K Roofing, Siding and Windows, we recommend approximately 16 inches of Owens Corning AttiCat blown-in insulation, which can save you up to 20% on your heating and cooling costs.* This level of insulation provides an R-Value of R-49. As you can see, compared to roll-out insulation at R-11 – R-19, blown-in insulation offers exceptional heat flow resistance. In addition to fiberglass insulation providing energy efficiency, it is non-combustible and non-corrosive, provided added safety.

Why Adding Attic Insulation Makes Cents (Yes, Cents!)

Adding attic insulation such as Atticat blown-in attic insulation from Owens Corning not only makes sense, it makes cents! Additional attic insulation provides a higher level of energy efficiency, which in turn saves you money each month – summer and winter.

Atticat Attic Insulation MarylandAtticat blown-in attic insulation is easily installed in just a few hours, and will provide energy efficiency for years to come. When your home has attic insulation with a high R-value (a measurement of energy efficiency), it helps prevent heat loss through the ceilings in your home. Warm air rises, and when insulation in your attic is insufficient, that warm air can pass through your ceilings into your attic, and escape through your roof. Efficient attic insulation provides a barrier, preventing the warm air from entering the attic.

During the hot summer months, energy efficient attic insulation work the same way, only in reverse. Sun and high temperatures warm your home from the roof down. Adequate insulation prevents the heat in your attic from entering your home. In addition to adequate insulation, you should also be sure that your attic is properly ventilated so that the warm air can escape.

According to energystar.gov, 15.5 inches of blown-in attic insulation can save you up to 20% on your heating and cooling costs. In fact, energystar.gov also states that the average US home spends $2,200 on home energy costs (http://www.energyhog.org/adult/pdf/EnergyFacts.pdf)  Add it up, and your Atticat insulation installation can save you hundreds of dollars each year. And because Atticat insulation is made of fiberglass, it is non-combustible and will not settle over time. Atticat insulation offers an R-Value rating of R-49 which is recommended for the Maryland climate zone.
