The average attic is only about the size of a bedroom, but it’s home to thousands of dollars worth of your most important investments: your roof, walls and windows. When you insulate an attic, you improve the overall energy efficiency of your home—and lower your heating bills in the process. In addition to protecting these valuable assets against moisture and heat loss, insulation makes homes safer by preventing heat from entering through uninsulated vents or ductwork. It can also reduce airborne dust and allergens that can cause respiratory problems for people with allergies or asthma. Minnetonka Spray Foam Insulation 

Blown-in, cellulose insulation: $0.50 – $1.00 per square foot

If you’re looking for an affordable way to insulate your attic, cellulose insulation is a good option. Typically it costs about $0.50 – $1.00 per square foot, which is much less than the prices of other types of insulation like fiberglass or foam. If you have a cramped and cluttered attic that makes it difficult for a professional installer to get all the way into the space with traditional methods, blown-in cellulose may be your best bet. This type of insulation is made from recycled newsprint, cardboard and other paper products so it won’t add any extra waste to landfills!

Spray foam insulation: $0.90 – $3.80 per square foot

Minnetonka spray foam insulation is the most expensive type of insulation. It provides the best thermal performance and seals gaps and cracks, but it’s also more expensive than other types of insulation.

Spray foam costs between $0.90 – $3.80 per square foot to install, depending on how much your attic needs to be insulated, the amount of material needed, and any custom work required for your project (such as cutting holes for vents or electrical outlets).

Batt, fiberglass and foam board insulation: $0.50 – $2.50 per square foot

In order to make your attic more comfortable, there are two types of insulation that you can install. These are batt and fiberglass. Both of them work great in attics and will help keep the space warm during the winter months. Batt insulation is made from fiberglass, which is a material used in many different things like boats and cars because it is lightweight and does not lose its shape easily. Batt insulation costs about $0.50-$2.50 per square foot, so if you need to cover an area larger than 100 feet by 100 feet, then it will cost anywhere from $25-$100 extra just for the material alone!

Fiberglass is also used as another type of low-density foam board insulation known as polyisocyanurate (PIR). This form is popular among homeowners because it’s less expensive than other forms, such as rock wool or cellulose, but still provides great R-value ratings (20). Foam board costs about $0.75-$1 per square foot, so if you’re looking at covering over 100 feet by 50 feet, then expect something like $150-$300 more than what we listed above!

Insulating your attic is a great investment in your home’s energy efficiency. 

To start, it’s important to understand that insulating your attic is a great investment in your home’s energy efficiency. It will save you money on energy bills and help you avoid expensive repairs by preventing moisture buildup in your attic that can cause mold and rot.

Insulation also increases the comfort level of your home by keeping it cool in summer and warm in winter. In addition, an insulated attic makes it easier to sell your house—a common practice among sellers is to improve the property before putting it up for sale—and, therefore, helps increase its value by up to 15%.

The cost of insulation varies depending on several factors: how much space needs coverage; what type of foam insulation (closed-cell or open-cell) is being used; how many roof vents exist that need covering; if any other modifications may be required (like adding ventilation fans). However, there are some general guidelines for estimating how much the project might cost:

  • A typical residential project would cost from $1 per square foot (for open-cell foam) up to $2 per square foot (for closed-cell foam). This includes materials only, so labor costs would need to be added if needed.


As you can see, the cost of attic insulation varies a lot depending on what kind of insulation you choose. You may also need to consider things like labor and shipping, which add to your final bill. Think about how much you’ll save on your energy bills as well as how much money this project could save over time. Then, when it comes time to budget your home improvements or repairs, don’t forget about this important step!
