Why Homeowners Should Add Insulation to Their Attics
Reviewed by Fadi Mamar, Co-founder
With the harsh winters that are common in Canada, it's essential for homeowners to ensure that their homes are well-insulated. One area that often gets overlooked is the attic. Adding insulation to your attic can have a range of benefits, from improved energy efficiency to cost savings.
Energy Efficiency
One of the primary benefits of adding insulation to your attic is improved energy efficiency. Insulation acts as a barrier that prevents heat from escaping your home in the winter and entering your home in the summer. This means that during the winter months, your home will stay warmer for longer, reducing the amount of energy you need to heat it. Similarly, during the summer months, insulation will keep your home cooler, reducing the need for air conditioning.
Cost Savings
In addition to improved energy efficiency, adding insulation to your attic can also lead to cost savings. If your home is poorly insulated, you may be spending a significant amount of money on heating and cooling costs. By adding attic insulation, you can reduce these costs and save money in the long run. While the upfront cost of adding insulation may seem high, the long-term savings can make it a worthwhile investment.
Comfort
A well-insulated home is also more comfortable to live in. By keeping your home warmer in the winter and cooler in the summer, you can enjoy a more comfortable living environment all year round. This can be particularly beneficial for those who have rooms that are difficult to heat or cool. With proper insulation, you can create a more consistent temperature throughout your home, making it more comfortable for everyone.
Noise Reduction
Another benefit of adding insulation to your attic is noise reduction. Insulation acts as a sound barrier, which means that it can help to reduce the amount of noise that enters your home from outside. This can be particularly beneficial if you live in a particularly noisy area or near a busy road. By reducing noise levels, you can create a more peaceful and relaxing living environment.
Increased Property Value
If you're looking to sell your home in the future, adding insulation to your attic can help to increase its value. Buyers are often willing to pay more money for a home that is energy-efficient, comfortable, and has lower energy bills. By adding insulation to your attic, you can make your home more attractive to potential buyers. In fact, according to the Appraisal Institute of Canada, adding insulation to your home can increase its value by up to five percent.
Environmental Benefits
By reducing your energy consumption, you can also reduce your environmental impact. By adding insulation to your attic, you can help to reduce your carbon footprint and contribute to a more sustainable future. This can be particularly important for those who are environmentally conscious and want to do their part to protect the planet.
Final Thoughts
Adding insulation to your attic can offer a range of benefits for homeowners. From improved energy efficiency and cost savings to increased comfort and noise reduction, there are many reasons to consider adding insulation to your attic. If you're looking to improve your home's insulation, be sure to hire a professional to ensure that the job is done correctly. With the right insulation, you can enjoy a more comfortable and energy-efficient home all year round. So, don't hesitate to invest in your home's insulation and start enjoying its benefits today.

Frequently Asked Questions
Is adding insulation to an attic worth it?
Yes, adding attic insulation is one of the most cost-effective home improvements a GTA homeowner can make. It reduces heating and cooling costs significantly, with many homeowners seeing energy savings of 15–25% annually. Given Ontario's harsh winters and humid summers, proper attic insulation pays for itself within a few years.
What is the 7 and 7 rule for a finished attic?
The 7 and 7 rule states that a finished attic space must have at least 7 feet of vertical headroom over at least 50% of the floor area, with no portion of the usable space having less than 5 feet of clearance. This guideline helps determine whether an attic qualifies as livable or conditioned space under building codes. In Ontario, this distinction affects how the space must be insulated and ventilated to meet Ontario Building Code requirements.
Is blowing in insulation in an attic a good idea?
Blown-in insulation, typically cellulose or fibreglass, is an excellent choice for GTA attics because it fills gaps and irregular spaces more effectively than batt insulation. It is particularly useful for topping up existing insulation or insulating attics with many obstructions like joists and pipes. Professional installation ensures the correct depth and density are achieved to meet Ontario's recommended R-60 insulation level for attics.
What happens if you don't have insulation in your attic?
Without adequate attic insulation, heat escapes rapidly through your roof during winter, forcing your furnace to work harder and driving up energy bills. In summer, the attic absorbs heat and transfers it into your living space, overworking your air conditioning system. Poor attic insulation can also lead to ice dams forming along your eaves in winter, which can cause serious water damage to your roof and interior.
What are the disadvantages of attic insulation?
The upfront installation cost can be a barrier for some homeowners, though government rebates through programmes like Canada Greener Homes can offset a significant portion of the expense. Improperly installed insulation can block soffit vents, reducing attic ventilation and leading to moisture buildup, mould, and premature roof deterioration. Additionally, adding insulation to a finished or partially finished attic can be more complex and costly than insulating an open, unfinished space.
