The Pros and Cons of Attic Insulation Types

Fiberglass batt, cellulose insulation, and foam are among the most popular types of attic insulation. In addition, fiberglass batts reduce air leakage, and foam is among the most popular types of attic insulation. Read about their pros and cons.

Foam Insulation Creates a Vapor Barrier.

While it can provide great thermal comfort, it’s also highly effective in controlling moisture and preventing mold growth. However, vapor barriers may damage walls, so consider this carefully. It may be a good idea to avoid them in your home if you live in a humid climate, but this isn’t practical.

There are many types of foam insulation. For example, a closed cell foam may need a minimum of two inches to create a vapor barrier. However, some closed-cell foams aren’t effective at creating a vapor barrier, and you’ll need to use a vapor-retarder to avoid condensation. Other foam insulation types do not have vapor barriers, meaning they will not prevent moisture from entering your house. You must consult professionals like those from Attic Man to ensure you get the proper insulation for your attic.

Cellulose Insulation Reduces Air Leakage.

Cellulose insulation has numerous benefits, including the ability to decrease air leakage. It prevents moisture from moving around the building and provides excellent sound insulation. It also minimizes mold growth. Cellulose insulation may be a good choice if you are concerned about mold growth. However, you should choose the proper type of insulation for your climate.

Cellulose insulation has the lowest embodied energy of all building materials. Comparable mineral insulation uses twenty to forty times more energy to produce. On the other hand, mineral insulation is made by burning fossil fuels in factories. Cellulose insulation uses locally available paper, and its process involves machines and furnaces, which are only 50% efficient. This saves the environment and helps protect the environment by reducing air leakage and its costs.

Rolls of Insulation are Easy to Install

While the installation process of attic insulation can be challenging, installing attic rolls is surprisingly simple. First, measuring the width of the attic studs, mark the length and width with a measuring tape. Next, apply the insulation to the attic studs and repeat the process.

You should ensure you’re equipped with the right tools. An extension cord will come in handy if you don’t have a toolbox. If you’re having trouble seeing, you may need an extension cord. Rolls of attic insulation are available in different densities and thicknesses.

Fiberglass Insulation is Inexpensive.

While fiberglass is one of the least expensive attic insulation options, it is not without its drawbacks. Although it is available widely, fiberglass is abrasive to the skin and lungs and requires protective equipment to handle. Although fiberglass is relatively inexpensive, the downsides can be significant. 

If you are interested in installing attic-level fiberglass insulation, you’ll be pleased to learn that installation can be done at home for a low cost. Fiberglass insulation can cost anywhere from $0.88 per square foot to $1.64 per square foot, depending on the coverage needed. So you’ll need to budget at least $300 to $500 for a 500-square-foot attic. Unfortunately, although fiberglass insulation is cheap, poor installation is a common problem.
