Different Types of Insulation

We might have mentioned this before, but having proper insulation is vital to your home. According to the Department of Energy, you can save up to 20 % on heating and cooling costs by adding insulation to floors, attics, crawlspaces and basements. Insulation not only prevents spikes in energy bills, but it will keep you at a comfortable temperature, no matter what the weather. However, you might be wondering what the different types of insulation are, and which one is right for you. To help you out, the pros at DFW Thermal have prepared a quick guide on the different types of insulation, so you can pick the one that works best for you!

Fiberglass

Fiberglass is one of the most common types of insulation used in American homes, because of its non-flammability, high R-value (the rating used to measure the thermal resistance of an insulation product) and low price. It is made of fine strands of interwoven glass and can either be blown in or installed in batts, blankets and rigid boards.

To be specific, the R-value of fiberglass batt insulation can go from 13 to 30, depending on the thickness of the batts. The cost per foot of fiberglass batt insulation can go from $0.20 to $1.00, depending on the density. Loose fill fiberglass, which is blown in, has an R-value range of 30 to 50 and a price range of $0.45 to $2.25 depending on the thickness.

Cellulose

Cellulose insulation is made of 75-85 % recycled material, primarily paper, which is treated to be fire and mold proof. Unlike fiberglass insulation, cellulose insulation can only be blown in. While loose fill fiberglass insulation might shift around, cellulose insulation does not shift drastically and might be better for preventing air leakages. Since cellulose is made of recycled material, it will not pollute the environment in manufacture or use, nor does it pose any serious health concerns. It has the same cost and R-value as loose-fill fiberglass insulation.

Spray Foam

Spray foam initially feels like shaving cream, but it hardens and turns into an impenetrable barrier. This type of insulation is well-known because it can be installed in the smallest of cracks, preventing the smallest air leakages. There are two types of spray foam insulation: open cell and closed cell. Open cell spray foam insulation that is 3.5 inches thick has an R-value of 12.6 and a price range of $1.70 to $2.50. Closed cell insulation with a thickness of 1 inch has an R-value of 6.5 and a price range of $1.30 to $2.00. In addition, closed cell is the only insulation classified as a flood-resistant material by FEMA.

Radiant Barrier

Radiant barrier does not rely on density to properly insulate your home. Instead, radiant barrier insulation works by reflecting radiant heat. This insulation type is usually installed in attics and prevents heat gain in your home during the summer. It can also be called reflective insulation as it is primarily made of reflective materials such as aluminum foil. According to the DOE, this type of insulation is great for hotter climates (aka Texas!) and can lower cooling costs by up to 10 % in sunny regions.

Radiant barrier’s insulation abilities can’t be measured using R-value as it does not provide insulation through thermal resistance. Get in touch with your local contractors to learn more about the value and price of radiant barrier insulation. DFW Thermal offers a free radiant barrier consultation, so you can learn more about this type of insulation.
