Before you invest in attic insulation, you should know what you’re getting yourself into. The following article will explain the various types of attic insulation available, the cost, and how to determine the R-value for your home. You’ll also learn about Vapor Barriers. These are the best insulation materials for attics because they prevent the flow of air from the attic to the living areas. You should make sure you install a sufficient amount of attic insulation to meet local building codes.

Cost of attic insulation

The cost of attic insulation varies greatly, depending on the type and size of your home. Homes with high ceilings and hallways may require more insulation than other types. Some homes may also require the installation of a knee wall to help with airflow. If your attic is not insulated properly, it may be at risk of mold growth and other problems. Using the right type of insulation can lower energy bills and save you money on heating and cooling bills.

Types of attic insulation

Fiberglass batts are one of the most popular types of attic insulation. These are made of plastic reinforced with tiny glass fibers and come in long rolls. The rolls can be easily cut into the required lengths and are easy to transport. They also offer the most square footage per package. If you’re worried about the toxicity of fiberglass, you may want to choose another type. However, you should be aware that fiberglass is not suitable for every home.

R-value of attic insulation

A higher R-value indicates better insulation. Without adequate attic insulation, air can easily enter the attic. An inadequate layer of insulation can result in 25 to 30 percent of your home’s heat loss. The R-Value of attic insulation is 3.7 times the depth of the insulation. The Building Code recommends R-values based on climate zones, which vary by region. In the Seattle area, R-values should be between R-38 and R-60.

Vapor barriers

If you want to add insulation to your attic, you may be wondering whether or not to install vapor barriers. The answer depends on the climate of your home and the current insulation. In colder climates, such as North America, a vapour barrier is essential to control heat loss and moisture. In warmer climates, however, it is not necessary. Besides, improperly installed vapour barriers can do more harm than good.

Fiberglass batts

Batts are the most common type of fiberglass attic insulation. They consist of rolled up sheets that are held together by adhesive binders. While batts are the easiest type of attic insulation to install, they can pose problems if there is something in the attic that interferes with their installation. Batts work best when there is no air coming from outside, so they are not a good option if you have an attic with any type of obstructions.


There are many benefits to using cotton attic insulation over fiberglass. The fibers are naturally resistant to fire and pests, and cotton is non-toxic, making it a good choice for people with allergies or chemical sensitivity. Cotton is also easier to install than fiberglass and has lower risk of fire, thanks to fewer fibers floating around. Cotton is also a more cost-effective option than fiberglass, and can save you money on your energy bills.

Spray foam

The benefits of spray foam attic insulation outweigh any disadvantages. Not only does it offer superior protection against water and air leaks, but it can also decrease noise levels in your home. It is also a relatively inexpensive and easy option for many homeowners. However, it should be installed by a professional to ensure the highest level of quality. Listed below are the pros and cons of this type of insulation. If you’re interested in insulating your attic, consider contacting Foam Tech, Inc. to install your spray foam insulation.
