Attic insulation plays a crucial role in maintaining the comfort and energy efficiency of your home, especially in a climate like Calgary’s, where temperatures can fluctuate drastically throughout the year. Among the various types of attic insulation available, blow-in insulation is gaining popularity due to its ease of installation and effectiveness. In this comprehensive guide, SmartFoam Insulations explores the cost of attic blow-in insulation in Calgary, helping homeowners make informed decisions about their insulation needs.

What is Attic Blow-In Insulation?

Attic blow-in insulation, also known as loose-fill insulation, is a type of thermal insulation that is installed by blowing or pouring loose insulation material into the attic space. This method allows for seamless coverage of irregularly shaped areas and hard-to-reach corners, providing uniform insulation throughout the attic. Common materials used for blow-in insulation include cellulose, fiberglass, and mineral wool, each offering different levels of thermal resistance and performance.

Benefits of Attic Blow-In Insulation

Attic blow-in insulation offers several benefits that make it a popular choice among homeowners in Calgary. Firstly, its seamless installation ensures complete coverage of the attic space, eliminating gaps and reducing heat loss. This results in improved energy efficiency and lower heating and cooling costs throughout the year. Additionally, blow-in insulation is highly effective at reducing air infiltration and preventing drafts, creating a more comfortable indoor environment with consistent temperatures and fewer hot or cold spots.

Factors Influencing Attic Blow-In Insulation Cost

Several factors can influence the cost of attic blow-in insulation in Calgary. These include the type of insulation material used, the R-value of the insulation, the size of the attic space, the accessibility of the attic, and the labor costs associated with installation. Understanding these factors is essential for homeowners planning their attic insulation projects and budgeting accordingly.

Type of Insulation Material

The cost of attic blow-in insulation can vary depending on the type of insulation material used. Cellulose insulation, made from recycled paper fibers treated with fire retardants, is often the most affordable option and offers excellent thermal performance. Fiberglass insulation, made from spun glass fibers, is slightly more expensive but provides comparable performance and durability. Mineral wool insulation, made from natural rock or slag fibers, is the most expensive option but offers superior fire resistance and soundproofing properties.

R-Value of the Insulation

The R-value of attic blow-in insulation refers to its thermal resistance, or ability to resist heat flow. The higher the R-value, the better the insulation’s performance. The R-value required for attic insulation in Calgary will depend on factors such as local climate conditions, building codes, and energy efficiency goals. Homeowners should consult with insulation professionals to determine the appropriate R-value for their attic insulation project.

Size of the Attic Space

The size of the attic space is another crucial factor in determining the cost of blow-in insulation. Larger attics will require more insulation material and labor to achieve complete coverage, resulting in higher overall costs. Additionally, attics with irregular shapes, obstacles, or multiple levels may require additional time and effort to insulate, further impacting the cost of the project.

Accessibility of the Attic

The accessibility of the attic plays a significant role in the cost of blow-in insulation installation. Attics that are easily accessible via stairs or attic hatches will typically incur lower labor costs compared to attics with limited access or tight spaces. Homeowners should consider the accessibility of their attic when budgeting for insulation installation and discuss any access challenges with insulation contractors beforehand.

Labor Costs

Labor costs associated with attic blow-in insulation installation can vary depending on the complexity of the project and the skill level of the installers. Factors such as the time required for preparation, insulation application, and cleanup will impact labor costs. Additionally, any additional services required, such as air sealing or moisture remediation, will add to the overall cost of the project. Homeowners should obtain quotes from multiple insulation contractors and compare labor costs to ensure they are getting a fair price for their project.

Additional Materials and Services

In addition to insulation material and labor costs, homeowners may require additional materials and services to complete their attic insulation project. This may include air sealing materials, vapor barriers, insulation supports, or protective coverings. These additional materials and services are essential for achieving optimal energy efficiency and performance but will add to the overall cost of the project.

Cost of Attic Blow-In Insulation in Calgary

The cost of attic blow-in insulation in Calgary typically ranges from $1.00 to $3.00 per square foot for materials and labor. However, the total cost of the project can vary depending on the factors mentioned above and the specific requirements of each project. Homeowners should obtain quotes from reputable insulation contractors and carefully review the scope of work and pricing details before proceeding with their attic insulation project.


In conclusion, understanding the cost of attic blow-in insulation in Calgary is essential for homeowners looking to improve the energy efficiency and comfort of their homes. By considering factors such as the type of insulation material, the R-value of the insulation, the size and accessibility of the attic space, labor costs, and additional materials and services, homeowners can make informed decisions about their attic insulation needs. With its numerous benefits and long-term savings, attic blow-in insulation is a worthwhile investment for homeowners in Calgary looking to create a more comfortable and energy-efficient living environment.
