How Different Types of Attic Insulation Work

Attic Insulation can reduce your energy bills by anywhere from 15-50% and help you protect your home’s drywall and wood framing. It can also prevent mold and mildew and keep pollutants from entering your indoor space. It’s important to understand how different types of attic insulation work so you can choose the best one for your home and budget.

The R-value of an insulation material is how much heat it can stop per inch, with higher numbers meaning more effective insulation. A professional can assess your attic and recommend the right R-value for your area.

Stop Air Leaks with Quality Attic Insulation

R-values are based on climate and home size, so the type of insulation you need will vary by region. There are several insulation options available, including fiberglass, cellulose, spray foam, and radiant barriers. Some have better soundproofing and fire resistance than others, while some are easier to install for DIYers and others require a professional’s expertise.

Fiberglass batt insulation, commonly known as blanket insulation, is a time-tested solution that works well for many homes. It consists of paper-like materials on both sides of a pink center made from fiberglass, and it comes pre-cut into sections or rolls. It’s affordable and easy for DIYers to work with, but it has the lowest R-value of all insulating materials at between 2.2 and 3.2 per inch.

Loose-fill or blown-in attic insulation consists of bags of loose cellulose, fiberglass, or rockwool that are blown into the attic with a machine designed for this purpose. It’s easiest to install during roof replacements, but it can also be a cost-effective way to add insulation to an existing home or re-insulate an attic with a high R-value. The installer will wear protective gear, depending on the type of insulation, to minimize exposure.
