Types Of Attic Insulation

When it comes to attic insulation, there are several types to choose from. We’ve listed the most common types of insulation used in attics to help you understand what choosing fiberglass, cellulose, and spray foam options.

Fiberglass Insulation

Fiberglass Attic Insulation
Fiberglass insulation is created by spinning tiny glass fibers into a mat. Afterward, the mat is cut into batts or blown in the desired area. It is a popular insulation material in North America because it is widely available and reasonably priced. This insulation is appropriate for attics, walls, and floors and can be used in new construction and retrofits. The R-value of fiberglass insulation for attic insulation ranges from R-2.9 to R-3.8 per inch of thickness. In North America, the recommended R-value for attics is R-49 to R-60, which can be achieved with a thickness of 12-15 inches of fiberglass insulation. This is accomplished by installing pre-cut fiberglass insulation batts that fit between the joists of your attic floor. It’s important to remember that the R-value is only one factor to consider when choosing attic insulation, and other considerations should include cost, ease of installation, and fire resistance. Our professional insulation tech’s can assess your attic space and recommend the appropriate type and thickness of insulation based on your specific needs and budget.

Cellulose Insulation

Cellulose Attic Insulation

Cellulose insulation is manufactured using recycled materials such as newspapers and cardboard. Because it is made from post-consumer waste, it is biodegradable and non-toxic, making it a popular choice for environmentally conscious homeowners. Cellulose insulation is easier to install than fiberglass insulation but can settle over time.

Cellulose insulation is an excellent choice for attics because it is a good insulator with a high R-value. The R-value of cellulose insulation per inch of thickness ranges from R-3.2 to R-3.8. This means that cellulose insulation has a high thermal resistance, keeping heat inside during the winter and outside during the summer. It is also an excellent choice for attic air sealing, which is necessary to prevent drafts and improve energy efficiency.

Typically, cellulose insulation is installed by blowing it into the attic space, allowing it to settle into tight spaces which helps to provide a tight seal. This method of installation is less messy and faster than fiberglass. Cellulose insulation is also gentler on the skin, eyes, and lungs than fiberglass insulation.

Spray Foam Insulation

Attic Insulation Spray Foam
Spray foam insulation is a recent option that can be applied as a liquid and expands to fill all the nooks and crannies in the attic, providing a tight seal and a high R-value. Spray foam insulation comes in two varieties: open-cell and closed-cell. Because of its high R-value and air-sealing properties, closed-cell spray foam insulation is an excellent choice for attics. The R-value of closed-cell spray foam insulation is approximately R-6.5 per inch of thickness. This is higher than other types of insulation, such as fiberglass and cellulose, indicating that it has a better thermal resistance and can keep heat inside in the winter and outside in the summer. It is also an excellent choice for attic air sealing, which is necessary to prevent drafts and improve energy efficiency. Another advantage of closed-cell spray foam insulation over cellulose insulation is that it does not provide a food source for pests, as it can help keep pests out of the attic and reduces the risk of insulation damage.

Costs and Savings

Any homeowner looking to improve energy efficiency and lower heating and cooling costs should consider installing attic insulation.

However, the price is understandably a concern for homeowners considering this type of home improvement. In this post, we’ll break down the cost of attic insulation, the potential long-term savings on energy bills, and any available rebates or incentives.

Attic insulation costs vary depending on the type of insulation used and the size of the attic. For a typical attic, the cost of insulation materials and professional installation ranges from $1,000 to $2,500. However, it is essential to note that this is only the initial outlay. In the long run, energy bill savings can be significant.

For example, if you pay $200 per month for heating and cooling and invest in attic insulation, you can generally expect a 20% reduction in your energy bills. That’s a $40 monthly savings or $480 per year, equating to a $4,800 savings over the course of ten years. As a result, the cost of attic insulation can pay for itself in energy savings over time.

Additionally, homeowners who invest in the attic insulation may be eligible for rebates or incentives. For example, the Ontario government offers a Home Energy Conservation Program that provides financial incentives to homeowners who improve the energy efficiency of their homes.

Costs and Savings

Does the age of my house affect my insulation?

In Ancaster, Ontario, buildings range in age from new construction to historic homes dating back over a century. The age of a building can play a significant role in determining potential attic problems. New construction (less than 5 years old): Attics in buildings less than 5 years old are likely to have few insulation problems, but this depends entirely on the developer. Most insulation and ventilation systems most likely up to date and in should be in good working order. Buildings aged 5 to 25 years: These structures may have issues with their attics, such as worn or damaged insulation or insufficient ventilation. Poor initial construction, a lack of maintenance, or exposure to the elements can all contribute to these problems. Buildings between 25 and 50 years old: These structures may have various attic issues, including outdated insulation, poor ventilation, and moisture damage. These problems can be caused by the building’s age, environmental exposure, and a need for proper maintenance. Buildings over 50 years old: These structures may have various attic issues, including outdated insulation, poor ventilation, moisture damage, and structural problems. These issues can be caused by the building’s age, exposure to the elements, and a lack of proper maintenance over time. It should be noted that these are general observations that vary depending on the condition and history of a building, as well as its maintenance.

How does attic insulation help to regulate temperature in the home and improve comfort?

Attic insulation is an important part of any home because it helps to regulate the temperature inside and improve overall comfort. The attic is usually the warmest part of the house in the summer and the coldest part of the house in the winter. This is due to the attic’s direct sun exposure, and heat from the sun’s rays can easily penetrate the roof, causing the attic to become extremely hot. The attic is also exposed to cold in the winter, which can cause the temperature inside the home to drop. Insulating the attic creates a barrier between the attic and the rest of the house. During the summer, the insulation helps keep heat out of the house by preventing it from entering the attic. Keeping the house cooler and less reliant on air conditioning means less overall energy drain. In the winter, attic insulation acts in the opposite direction, trapping heat inside the home and lowering the need for heating which often results in significant energy bill savings. Proper insulation also contributes to overall home comfort. Attic insulation can reduce the heat that enters the home during the summer, making it more comfortable to live in. It can keep the heat inside the house in the winter, making it warmer and more comfortable. Attic insulation also helps to improve indoor air quality by preventing draughts and moisture from entering the attic, where mold and mildew can grow.

How does attic insulation protect the home from moisture damage?

Attic insulation is critical in protecting a home from moisture damage. Moisture can cause various problems in the attic, including mold and mildew growth, which can lead to serious health issues and structural damage. Several factors, including high humidity levels, roof leaks, and inadequate ventilation, can cause moisture in the attic, especially during warmer months. By reducing moisture in the attic, attic insulation helps to protect the home from moisture damage. The insulation forms a barrier between the attic and the rest of the house, keeping it dry. Proper attic insulation also helps to improve attic ventilation. Insulation helps to keep drafts out, which can help to keep moisture out of the attic. Furthermore, proper ventilation can help lower the attic’s temperature, preventing moisture buildup. Another way that attic insulation protects the home from moisture damage is by preventing roof leaks. Insulation helps to keep moisture out of the attic by sealing gaps and cracks in the roof.

How does attic insulation affect the air quality in the home?

Attic insulation has a significant impact on the air quality in the home. Insulation creates a barrier between the attic and the rest of the house, which can help to improve indoor air quality. Attic insulation helps to improve air quality by preventing draughts. Drafts can allow cold air into the home in the winter and hot air into the home in the summer. This can make the house uncomfortable to live in and cause the HVAC system to work harder than necessary, lowering the air quality in the home. Improving indoor air quality is critical for your health as well as the health of those who share your space. The air inside our homes and businesses can be more polluted than the air outside due to various factors, including chemicals, cigarette smoke, dust mites, mold, and mildew. Insulation helps to keep draughts at bay, which improves overall air quality by controlling the temperature inside the home more consistently.

How does Ancasters different seasons affect the importance of attic insulation?

In Ancaster, Ontario, attic insulation is critical for maintaining a comfortable temperature inside the home throughout the year. During the winter, when temperatures can drop below -20 degrees Celsius with wind chill, proper attic insulation keeps heat from escaping the house, keeping it warm and lowering heating costs. Ancaster’s wind direction and elevation can significantly impact temperature, making it feel even colder than it is. A well-insulated attic creates a barrier between the living space and the harsh winter weather outside, making heating the home more energy efficient and cost-effective. In the summer, when temperatures reach 30 degrees Celsius, insulation helps keep heat out of the attic, keeping the home cooler and lowering cooling costs. Ancaster’s humidity can make it feel even hotter than it is. A well-insulated attic can help keep the house cool and reduce the load on air conditioning systems, making cooling the home more energy efficient and cost-effective. Furthermore, proper attic insulation can prevent moisture buildup, mold growth, and structural damage. During the wet seasons in Ancaster, spring, and autumn, attic insulation can keep water out of the attic and prevent condensation from forming. These can help keep the home dry, protect the structural integrity, and avoid mold growth, which can be hazardous to one’s health.

You were all very polite and I appreciated how you explained everything related to our old home.  I guess you’ve seen a lot of flipped houses like ours that contractors didn’t think to upgrade the insulation.  Thanks again.
