Spray Foam Insulation In Ancaster, ON

Spray foam insulation services in Ancaster, Ontario, are intended to assist homeowners in improving their home’s energy efficiency while combating seasonal weather patterns and the local climate.

Ancaster is a city in the Greater Hamilton Area with a humid continental climate and four distinct seasons. The weather is defined by cold winters and hot summers. The average temperature in January is around -8°C, and the average in July is around 22°C. The area receives approximately 790mm of precipitation annually, most of which falls during the spring and summer. Ancaster’s snowfall varies significantly yearly, but the average is around 150cm.

Spray foam insulation is a popular choice among Ancaster homeowners because it is an efficient way to insulate the attic, walls, and other home areas. The insulation is applied as a liquid, which expands to fill the space and create an airtight seal. The goal is to lower energy costs and make the home more comfortable. Furthermore, spray foam insulation can help to reduce moisture levels in the attic, preventing mold and mildew growth.

Spray foam insulation comes in two varieties: closed cell and open-cell. Closed-cell foam has a higher R-value per inch and is denser, making it more effective at insulating and preventing air infiltration. It is also more moisture-resistant and can function as a vapor barrier. Open-cell foam has a lower R-value per inch and is less dense, but it is more flexible and can be used in tight spaces. Open-cell foam is also less expensive than closed-cell foam.

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.

Attic Spray Foam Insulation

Costs and Savings

How does spray foam insulation compare to fiberglass and cellulose insulation?

Insulation is used year-round, not just during the colder months, to keep a house comfortable for its inhabitants. While each serves its purpose uniquely, the benefits are not interchangeable.

Very fine glass fibers are woven together to create fiberglass insulation, which is then used to insulate buildings. It is purchased in batts or rolls and then cut to size for installation in the spaces between a wall’s studs. Fiberglass is an excellent material to use if you need to insulate an already-built house.

Cellulose insulation is treated with fire-retardant chemicals before it is made into usable products and installed in homes; the recycled paper products used in its production include things like old newspapers. Blown cellulose insulation is the most common installation method in the walls or attic. As an added insulation layer, cellulose is an excellent option for preexisting houses.

Insulation in spray foam is applied as a liquid, then dries, expands, and fills the area. A seal is created that keeps out air and helps to reduce draughts. When building or renovating a home, spray foam insulation is a popular and effective option.

Spray foam insulation has a higher R-value per inch than fiberglass and cellulose insulation, making it more effective at insulating and preventing air infiltration. To top it all off, it creates an airtight seal, making it even better at blocking air leaks and draughts. Insulation made from spray foam lasts much longer and is much more durable than alternatives like fiberglass or cellulose. On the other hand, fiberglass and cellulose insulation are more affordable and simpler to set up than spray foam insulation.

What is the R-value of spray foam insulation?

The R-value of insulation is a quantitative measure of its ability to impede heat flow. A higher R-value means the insulation is more effective at blocking summer heat and keeping winter heat inside.

Insulation utilizing spray foam has a higher R-value per inch than any other type of insulation. This means it does a better job insulating a home in the winter and keeping the heat out in the summer. Spray foam insulation typically has an R-value between R-3.5 and R-6.5 per inch, though this can vary depending on the type of foam and the thickness of the insulation.

The R-value of insulation may degrade over time due to air leaks, humidity, and temperature changes. That’s why it’s crucial to get an expert to verify that the insulation is still effective.

When selecting insulation, R-value isn’t the only thing to think about; soundproofing, fire resistance, and moisture resistance are just as crucial. In addition to its high R-value, the versatility and efficiency of spray foam insulation make it an excellent insulation choice for homes.

How long does spray foam insulation last?

Insulation in spray foam can last for many years, provided that it is installed accurately and maintained regularly. The exact amount of time that spray foam insulation will remain effective will be determined by several factors, including the type of foam used, the climate, and the degree to which the insulation was protected from damage.

Spray foam insulation is an option for insulation that is very durable and will last for a very long time, which is one of the benefits of using spray foam insulation. It is manufactured to resist moisture and air leaks, common factors in the deterioration of other types of insulation over time. Insulation created with spray foam has the potential to last for decades and maintain its insulating qualities throughout that time.

However, it is essential to remember that the insulation can be affected by factors such as UV rays and temperature changes. Because of this, it is vital to have a trained professional check the insulation regularly to ensure that it is still in good condition and provides the desired level of insulation. In addition, it is essential to ensure that the insulation is correctly installed and that there are no air leaks or draughts, as both of these factors can significantly impact the insulation’s effectiveness.

Can spray foam insulation be used to insulate attics, walls, and floors?

Yes, attics, walls, and floors can all be insulated with the help of spray foam insulation, which is a viable option.

Insulation applied as a liquid before it expands to fill the space it is being applied to is known as spray foam insulation. This type of insulation is typically used in attics, creating a waterproof seal to air, which helps prevent air leaks and draughts. Because it can be applied to any shape or surface, it can insulate various areas of a house, including the attic, the walls, and the floors.

Spray foam insulation can be used in attics to improve a home’s ability to retain both heats during the winter and cool air during the summer. This can be accomplished by properly insulating the attic. Additionally, it can help to prevent the buildup of moisture in the attic, which can lead to the growth of mold and mildew as well as damage to the structure of the home.

Walls that have been insulated with spray foam insulation can help reduce draughts and air leaks, thereby contributing to an increase in the home’s energy efficiency. In addition, it could lessen the amount of noise from the street that is brought into the house.

Insulating the home’s floors with spray foam insulation makes it possible to help retain the heat inside the house during the colder months and the cool air during the warmer months. Additionally, it can aid in preventing draughts and contribute to the increased energy efficiency of the home.

How can homeowners tell if their existing insulation is in need of replacement or upgrading?

By keeping an eye out for sure signs, homeowners can determine whether or not the insulation in their homes currently needs to be replaced or upgraded.

If you have draughts in your home or specific rooms that are either too hot or too cold all the time, this could indicate that the insulation needs to be replaced or upgraded. Air leaks or insufficient insulation might be to blame for this problem.

If a homeowner notices that their monthly energy bills are higher than usual, this is another indication that the insulation in their home may need to be replaced or upgraded. This is likely due to inadequate insulation, which prevents the building from being adequately protected from heat and cold.

The mold and moisture levels in the attic are other things that homeowners should look for. Inadequate insulation or air leaks may be to blame for moisture in the attic. If mold or moisture is present, it is critical to address the problem as soon as it is discovered because it can result in health problems and damage to the structure.

In addition, homeowners should inspect the insulation itself; if it is visibly damaged, such as having holes or a discolored appearance, or if it is settling and compressing, these are indications that the insulation is not providing the level of insulation that was intended. The insulation either needs to be upgraded or replaced.

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.
