Fiberglass insulation is essential to the energy efficiency and comfort of a home. It blocks heat from escaping during the winter and in the summer, reducing strain on heating and cooling systems and saving money on your energy bills. It also prevents ice dams and other moisture problems by keeping the attic well-insulated.

The type of attic insulation you choose depends on the R-value you need, a number that indicates how well the material resists heat flow. There are 4 types of attic insulation to consider, with different advantages and disadvantages.

Fiberglass batt insulation is the most common attic insulation. Resembling pink cotton candy and clouds, it consists of tiny fiberglass slivers that are fused with a chemical vapor. It has a high R-value of R-2.9-R-3.8 per inch, meaning it provides good thermal protection in most climates. Its main drawbacks include being expensive and producing dust during installation.

How Attic Insulation Can Reduce Your Utility Bills

Another popular option is blown-in cellulose. This is similar to fiberglass batt insulation, but instead of a synthetic fiber, it’s made from recycled materials such as paper and wood. It’s treated with boric acid to be fire-resistant and is more environmentally friendly than fiberglass. It’s also less irritating to the skin.

Spray foam is one of the more expensive attic insulation options, but it offers a very high R-value per inch and acts as an air barrier to seal leaks and crevices. It is only available from professionals and requires specialized equipment due to its chemicals. It also releases gases during and after installation, which requires adequate ventilation.
