How Much to Add Insulation to Your Attic

Do you want to know how much to add insulation to your attic? You may not be aware that loose-fill cellulose insulation is not the same as fiberglass batt insulation, which is heavy and is also prone to deterioration. But the truth is that it can be a significant energy-saving measure. In addition, it can save you money on energy bills. In this article, we will examine how much it costs to add cellulose insulation to an unfinished attic.

Cost of adding insulation to an unfinished attic

The cost of adding insulation to an unfinished attic varies widely and will depend on several factors, including the amount of insulation needed, the size and condition of the attic, and the type of material. Many homeowners, however, are happy to spend an extra couple hundred dollars to improve the comfort of their home, and insulated attics have numerous advantages. Not only do they help to reduce their utility costs, but they also improve the look and feel of the home.

However, adding insulation to an attic can be expensive, especially in colder climates. Depending on the type of insulation, it could cost up to $2,100. Some homeowners may not be aware that insulating their attic will add several inches of insulation to their roof, and this process could increase the cost of the overall project. For this reason, homeowners should first estimate the cost of adding insulation to an unfinished attic before committing to a specific project.

Cost of Insulation Depends

The cost of adding insulation to an unfinished attic can vary, and it depends on the type of material and the R-value of the insulation. If you are a do-it-yourselfer, renting a blowing machine may be a cheaper option. Just be sure to include all of the parts of the attic in your budget, because insulating just the floor and ceiling will not be enough.

You can add insulation to an unfinished attic by installing fiberglass or cellulose. Fiberglass and cellulose are easy to install and come in different forms. Fiberglass insulation can be blown in or data form. Cellulose, on the other hand, is cheaper but is prone to deterioration. You can also choose between the two, depending on your budget. Regardless of the method you choose, the cost of adding insulation to an unfinished attic should help lower your energy bills and make your home more comfortable.

Blown-in Approach

If you have a finished attic, a blown-in approach is the easiest way to add insulation to the space. It involves less tear out and rebuilding afterwards. A blown-in system can reach all the rafters and wall joists. Adding insulation to an unfinished attic is a good way to add more space for storage and more. You can also use this space for air-conditioning ducts and use it as an additional room in your home.

The cost of adding insulation to an unfinished attic depends on the type of material you use. Some of the most popular types of insulation are made of cellulose, and the cost of the materials used will vary depending on the thickness of the material. However, cellulose is cheaper than fiberglass and cellulose, and it can also be installed more quickly and easily. As long as you have access to the right tools, you should have no problem getting the job done.

Cost of adding insulation to a fiberglass batt attic

Adding fiberglass batt insulation to your attic is one of the easiest ways to keep your home’s attic cool and comfortable. This material comes in large packages that can be installed inside the walls or attic space. It provides insulation and prevents air penetration, and can be cut to fit around vents. Bats vary in size, thickness, and R-value. They are easy to install in open attics and are relatively inexpensive.

Most homes have some type of attic insulation, but many are not equipped to install it properly. While fiberglass rolls are the most common type of insulation, fiberglass batts are easier to install. Most homes already have some insulation, so adding more will improve its overall insulation. In addition, fiberglass batt insulation is easy to remove if it is no longer needed. Once installed, you will be able to enjoy the lower energy bills for years to come.

Hire Professional

Batts can be installed yourself, or hired to be installed by a professional. Batts are long, puffy sheets of insulation held together by an adhesive vapor barrier. Professional installers usually use a blower to distribute the insulation evenly and avoid air pockets or obstructions. Most insulation manufacturers also produce “rulers” for their products. A good installer will make them according to your measurements.

R-value: The R-value of an insulation material determines its thermal capability. The R-value of a particular material is based on its thickness and density. In addition, the thickness of your attic’s insulation determines its R-value. It is recommended that you install insulation that has a minimum R-value of R-30. If you can afford it, you can invest in high-quality insulation to improve your home’s comfort.

Cost of Fiber Glass Attic Insulation

Depending on your budget, you can save as much as 10% to 50% on your energy bill by installing fiberglass batt insulation. Adding insulation to an attic is a relatively simple and straightforward home improvement project, but it does require professional help. Get several estimates to ensure that you get the best deal on your insulation project. Remember, a lowball bid may not be the best deal because it does not include blocking vents and other necessary work. You might also want to check into financing options. Some insulation contractors will even accept payments over one or two years.

The cost of adding fiberglass batt insulation to an attic is roughly $350 per square foot. It’s possible to install fiberglass batt insulation yourself, but you can also hire a professional to do it for you. If you’re confident enough to complete the project, you can save money by performing the installation yourself. In addition to fiberglass batt insulation, you can also consider the cost of spray foam insulation, which is the most expensive option. The cost of spray foam is generally twice as much as batt insulation.

Cost of installing loose-fill cellulose insulation in an unfinished attic

There are many pros and cons to installing loose-fill cellulose insulation in an attic, so it’s important to understand the cost of installation. While it may be a relatively small investment, it can lead to significant energy savings and improved comfort. Whether you choose to DIY or hire a professional, the process will require a few hours of work. In addition, it’s important to consider the structural integrity of your home when choosing the type of insulation.

The typical cost of installing loose-fill cellulose in an unfinished attic is $600 to $3,500. This material is made from wood pulp and typically contains post-consumer recycled content. This type of insulation is durable and insect and flame-resistant, and is available in damp or dense-pack forms. Depending on the application requirements, you can choose between two types: dense-pack cellulose for vertical installation, and wet-spray cellulose for horizontal installation.


Loose-fill cellulose insulation is easy to install. However, it may create some dust, which makes it difficult to handle for DIYers. Mineral wool batts are more expensive than cellulose, but they are naturally fire-resistant and block sound transmission. When you choose a type of insulation for an attic, you should check the depth of the current insulation and estimate the R-value. In addition, you should dispose of the old insulation or repair any damage in the insulation itself.

Fiberglass or blown-in cellulose insulation is an inexpensive option but may not be as effective. This material is the most common type of insulation. Unlike fiberglass, it is eco-friendly and biodegradable, and has the highest R-value of any material. Therefore, if you’re considering insulating your attic, consider adding cellulose insulation. It’s not only environmentally friendly, but it will also help reduce your energy bills.

Cost to install Cellulose Insulation

The cost to install cellulose insulation in an unfinished attic varies widely. Loose-fill cellulose is the least expensive, and it only costs $0.8 to $1.30 per square foot. Its R-value is approximately 3.5 per inch. Depending on the type of cellulose insulation you choose, you could save as much as $2085. You can do the work yourself and save money on the cost but remember that you don’t get a warranty on your labor.

The cost of loose-fill cellulose insulation in an uncompleted attic is approximately $2.50 per square foot, and the contractor will charge a service fee of around 10 percent. There are other types of cellulose insulation available, including fiberglass. Both materials are cheap to purchase, but you may need to rent a blower to get the job done properly. You can also opt to blow-in cellulose insulation using a blower, which costs between $1.40 and $2.10 per square foot.

R- Value

While the R-value of cellulose insulation will vary, the cost of Rockwool blown insulation will range from $1.40 to $2.20 per square foot. It is not as widely available as cellulose, but it can offer more benefits, including fire resistance, a high R-value, and sound dampening. Unlike cellulose, rock wool is a byproduct of the steel industry. It is durable and resistant to insects and pests and can be installed in unfinished attics.
