Attic Insulation: A Crucial Project for Homeowners
Attic insulation is one of the most essential things a homeowner must do to make sure the home is well-insulated.
Good insulation allows the home to maintain a desirable temperature throughout the seasons. Attic insulation can reduce heating and cooling bills.
But how is attic insulation done? This requires a barrier to be placed to prevent energy flow from the interior to the exterior. With good attic insulation, the home stays warm when it is cold outside and cool when the weather is hot.
By insulating the attic properly, the home becomes more energy-efficient and prevents moisture build-up that causes damage.
Benefits of Proper Attic Insulation
To emphasize why attic insulation is so important, here is a more detailed overview to help you understand.
1.Energy Efficiency and Cost Savings:
- Attic insulation prevents heat loss in winter and heat gain in summer, thus reducing the pressure on your heating and cooling systems.
- Efficiency results in lower energy bills and enhanced comfort in the home.
- A well-insulated attic can significantly reduce heating and cooling bills.
2.Increased Comfort and Indoor Air Quality:
- Insulation helps to regulate indoor temperature to make the home warmer in wintertime and cooler in the summertime.
- It also reduces condensation and moisture buildup which improves air quality in the home. Moisture buildup, if left unchecked, can lead to mold and mildew growth.
- Good attic insulation also lowers noise transmission from outside to promote a quieter home environment.
3.Increased Home Value and Durability:
- A properly insulated attic can increase home value at resale as homebuyers seek energy-efficient homes.
- Good insulation also protects the roof from moisture and heat damage. This prevents costly repairs and extends the life of the roof structure.
4.Eliminate Pests
- Did you know that rodents, bugs, and even birds love attics? They are unwanted guests that can cause damage to your home.
- Attic insulation can deter pests by creating a barrier. Animals are less likely to stay in the attic because insulation materials are not good for feeding or nesting.
5.Sustainability:
- Lower energy usage due to proper insulation also reduces carbon emissions, a huge contribution to environmental preservation.
6.Additional Benefits:
- Good insulation prevents ice dam formation on the roof which leads to roof damage.
- It also prevents pollen, dust, and other allergens to promote better indoor air quality.
- Some types of attic insulation are also fire-resistant. Although insulation alone cannot prevent a fire, some insulation materials can slow the spread of flames to reduce property damage.
Attic insulation is a good investment that offers numerous benefits to homeowners. From promoting better health, a more comfortable home, and lower energy bills, the money you spend on attic insulation is worth every cent.

Types of Attic Insulation Available in Canada
Choosing the right type of attic insulation is essential for energy efficiency, comfort, and durability. Homes in Canada endure severe seasonal changes.
When considering the different types of attic insulation, priority should be placed on the product’s R-value or thermal resistance.
Good insulation must reach the thermal resistance that will keep warm air out in the summer and winter. The R-value plays a critical role in the efficiency of attic insulation.
Below you will find the different attic insulation types and their pros and cons.
1. Fiberglass Batt Insulation
- Pre-cut spun glass fiber panels.
- Ideal for standard joist spacing and accessible attics.
- Pros: Easy to install, affordable, and fire-resistant.
- Cons: Gaps can lower effectiveness. They are not suitable for irregular spaces.
- R-Value: ~R-3.0 to R-3.7 per inch.
2. Blown-In Cellulose Insulation
- Loose-fill recycled paper material treated with fire retardants.
- Suitable for filling gaps or irregular attic spaces.
- Pros: Environment-friendly, good air sealing, and effective in narrow spots.
- Cons: May settle over time, thus reducing R-value.
- R-Value: ~R-3.2 to R-3.8 per inch.
3. Spray Foam Insulation (Open or Closed Cell)
- Liquid foam that expands and hardens in place.
- Good for maximum air sealing and moisture control.
- Pros: Seals air leaks and good moisture barrier.
- Cons: More expensive and requires professional installation.
- R-Value: Open-cell: ~R-3.5 to R-4.0 per inch; Closed-cell: ~R-6.0 to R-7.0 per inch
4. Mineral Wool (Rock Wool) Insulation

Cost Comparison: Attic Insulation Types in Canada
In Canada, the cost of attic insulation can vary depending on the material and installation method. They typically range from $1.50 to $4.00 per square foot.
Fiberglass and blown-in cellulose are the cheapest types while spray foam and cellulose poured or wet-spray are more expensive.
Below is a breakdown of estimated costs for the different types of attic insulation available.
1. Fiberglass:
- Batts: $0.30 - $1.50 per square foot.
- Loose-fill (blown-in): $0.50 - $1.10 per square foot.
2. Cellulose:
- Blown-in: $1.00 - $2.30 per square foot.
- Poured or wet-spray: Can be more expensive than standard blown-in cellulose.
3. Spray Foam:
- Cost: $3.00 - $5.00 per square foot.
4. Rockwool:
- Cost: $1.40 - $2.10 per square foot.
The cost of upgrading your attic insulation will depend on several factors including:
- The size of the attic (in square feet)
- The existing type of insulation material in the attic
- Required treatments before the insulation product can be installed
- Depth of the existing insulation
- Scope of the project
Expect to spend between $1.50 and $3.50 per foot or about $1,700 to $2,100 for attic insulation.
Spray foam is the most expensive insulation and is ideal for new buildings and for noise reduction.
Blown-in insulation is the cheapest and is ideal for old attics.
The square footage for insulation has a huge impact on the overall cost. The bigger the area, the higher the budget required for insulation. The accessibility of the attic will also be considered by the contractor when estimating costs.
The contractor could charge around $70 per hour. It is advisable to hire an electrician to insulate around electric cables and junction boxes. This would increase your overall costs.

Choosing DIY vs. Professional Attic Insulation
Both DIY and professional attic insulation offer distinct advantages.
DIY insulation could help you save on labour costs but professional installation ensures expert installation and potentially higher energy savings.
Professionals use proper equipment and are knowledgeable about the methods of installation, thereby leading to faster completion and more efficient work.
You can save a lot of time and effort with professional attic insulation. It can also help you save money in the long term because professionally installed insulation lasts longer.
DIY is time-consuming and entails hard work, especially if you need to remove old insulation or if the attic space is complex.
If you are not experienced or don’t have the proper tools, your work may not produce optimal results which would be a waste of time and materials.
If your attic is hard to reach or has irregular spaces, special equipment like spray foam with professional installation is recommended.
