Types of Attic Insulation/Modular Home

Updated: Jan 10, 2023

If you want to keep your home warm and comfortable, it is important to have proper attic insulation. By blocking the heat and cold from your attic, you will not only save energy but also keep your home warmer and reduce outside noise. There are several types of attic insulation, each with its own benefits and disadvantages. It is important to choose the right type for your specific needs.

Types of Attic Insulation

The most common attic insulation is fiberglass batts. These flexible fiber sheets are used in conjunction with other insulation to achieve the desired R-value. Batts can be purchased unfaced, or with a paper backing. They need to be placed perpendicular to the old layer of insulation to prevent moisture from seeping between layers.


Loose-fill attic insulation is another popular option. This type of insulation is made from cellulose, metal wool, or fiberglass. It is typically blown into the attic to create a dense barrier against airflow and heat loss. You can purchase loose-fill insulation in rolls and sheets, or you may want to cut it to fit uneven spaces.


Foam insulation is a good choice for insulating your attic. While this type of attic insulation is not cheap, it can be the best solution for an attic that has an irregular joist layout. In fact, the Department of Energy recommends that you add at least one layer of this type of insulation.


However, it can be dangerous, so make sure to wear a mask, goggles, and protective clothing.

Attic insulation can help you keep your home warmer in the winter and cooler in the summer. It can also help control rodent infestations and reduce the risk of leaks in your ceiling. Proper attic insulation can also reduce the noise of storms and other external sources of noise. A modular home can benefit your insulation benefits.


When you are installing your attic insulation, make sure to take the time to install it in a way that will prevent thermal bridging. Thermal bridging is when airflow through your home becomes trapped between the insulation and the framing of your attic. Using a vapor barrier can help.

Spray foam attic insulation can be a great option for an attic with an unusually irregular joist layout. However, this type of insulation is expensive to install and cannot be removed once it has been installed.


For a more affordable solution, consider blanket insulation. Blankets are made from a variety of materials, such as cotton, plastic, and mineral wool. High-density blankets can have an


R-value between R-3.7 and R-4.3 per inch of thickness. Some types of blankets are woven with recycled materials.


Attic insulation is a small investment that can pay for itself in just a year. With proper installation, you will be able to enjoy the benefits of attic insulation, including increased energy efficiency, lower air conditioning costs, and fewer maintenance issues. A properly insulated attic can also keep you from dealing with the hazards of a frozen pipe or the damage of a moldy attic.
