The Right Way to install Blown-in attic Insulation.

Blown-in attic insulation is just as important as other types of insulation when it comes to keeping your home at a comfortable temperature all year long. It keeps your home warm in the winter and cools it during the summer, reducing your energy bills and carbon footprint.

Blown-in attic insulation is a popular choice among Toronto homeowners because it works well and is inexpensive. In this article, we will discuss the right way to insulate attics in Toronto with blown-in attic insulation.

What is Blown-in Attic Insulation?

Blown-in attic insulation is a type of insulation material that is installed in the attic of a building to reduce heat transfer between the living space below and the outside environment. This type of insulation is made of small, loose fibers of materials such as fiberglass, cellulose, or mineral wool that are blown into the attic space using a special machine.

The process involves cutting a small hole in the attic ceiling and inserting a hose into the space through which the insulation material is blown. The material fills the space between the ceiling joists and other obstructions, creating a barrier that slows the transfer of heat through the roof and into the living space.

Blown-in attic insulation is an effective way to improve the energy efficiency of a building, as it reduces the amount of heat lost in the winter and gained in the summer. It also helps reduce energy bills and improve indoor comfort levels. Blown-in attic insulation is also a low-cost and non-intrusive way to insulate a building. It can be installed quickly and with little trouble for the people who live there.

The Right Way to Insulate Attics with Blown-in Attic Insulation:

Stage 1: Inspect the Attic Space

Before installing the blown-in attic insulation, it is important to inspect the attic space thoroughly. This inspection helps expose any problems that could make it hard to insulate the attic and makes sure that the attic is ready to be insulated.

The first step in inspecting the attic space is to check for any signs of moisture or water damage. This may include water stains on the ceiling or walls, mold growth, or damp insulation. If any moisture issues are present, they will need to be addressed before the insulation process begins.

Next, check the ventilation in the attic. Adequate ventilation is necessary to prevent moisture buildup and regulate temperature. The attic should have proper venting, including vents in the roof and soffit vents, to allow for proper air circulation.

The condition of the existing insulation should also be evaluated. If the insulation is damaged, compressed, or damp, it will need to be removed before new insulation is installed. If the existing insulation is in good condition, it can be left in place and used as a base for the new insulation.

It is also important to check the access to the attic. The attic should have a clear and safe access point, such as a pull-down ladder or staircase. If the existing access is not safe or suitable, it may need to be replaced before the insulation process begins.

Before carrying out attic insulation, it is important to examine it for any problems so that they can be fixed and then the insulation will be correctly blown in for the best results.

Stage 2: Calculate the Required R-Value

Once the attic space has been inspected, the next step in insulating with blown-in attic insulation is to calculate the required R-value. The R-value is a measure of the insulation’s ability to resist heat flow, with higher values showing better insulation.

To figure out the required R-value for attics in Toronto, you need to look at several things, such as the local building codes, the climate zone, and the type of insulation being used.

According to the Ontario Building Code, the minimum R-value required for attics in Toronto is R-50. However, this may vary based on the specific construction and location of the building, as well as the energy efficiency goals of the homeowner.

To calculate the required R-value for the attic, it is important to measure the total square footage of the attic space. This is done by measuring the length and width of the attic floor and multiplying the two measurements together.

Once the total square footage has been determined, the required R-value is calculated using a formula that considers the climate zone, which in Toronto is Zone 6. For Zone 6, the recommended R-value for attics is between R-50 and R-60.

It’s important to remember that ventilation and the condition of the insulation already in your attic change the R-value that’s needed. Talk to a professional insulation contractor who will help calculate the right R-value and ensure that the insulation is installed correctly for maximum effectiveness.

Stage 3: Prepare the Attic Space

After inspecting the attic space and calculating the required R-value for insulation, the next stage is to prepare the attic space for blown-in attic insulation. This involves several steps to ensure the insulation is installed correctly and effectively.

Start by evaluating and removing existing insulation if necessary. Insulation that is broken, wet, or compressed should be taken out to make sure that the insulation is properly installed and works well. If the existing insulation is in good condition, it can be left in place as a base for the new insulation.

Any air leaks in the attic space should be identified and sealed. Air leaks can occur around vents, ducts, and light fixtures and may significantly reduce the effectiveness of the insulation. Sealing these leaks will make the house use less energy and keep air from escaping or getting into the attic.

After sealing the air leaks, the attic should be cleared of any debris or items that could interfere with the installation of the blown-in insulation. This includes any stored items or debris from the construction process.

The next step is to install any necessary baffles or chutes to ensure proper ventilation and prevent the blown-in attic insulation from blocking the airflow. Baffles are installed between the rafters to provide a channel for air to flow from the soffit vents to the roof vents. Chutes are installed on the roof deck to provide a clear path for air to flow from the attic to the roof vents. These are necessary to prevent moisture buildup and maintain proper attic ventilation.

When getting the attic ready for blown-in insulation, it’s important to pay attention to the details and do the right things to make sure the insulation works well and saves as much energy as possible. By getting the attic ready in the right way, you will get long-lasting insulation and save a lot of energy.

Stage 4: Install the Blown-in Insulation

The installation step is important if you want your blown-in attic insulation to save you money by keeping your home as energy efficient as possible. As discussed earlier, the attic must be prepared before the insulation materials are blown in. This means getting rid of any old or damaged insulation, sealing any air leaks, cleaning out the space, and, if needed, installing baffles or chutes.

The installation of the blown-in insulation should begin at the farthest point from the attic access point and work towards the access point. This ensures that the insulation is dispersed and no areas are missed.

A professional insulation contractor will use a special machine to blow the loose-fill insulation material evenly across the attic space. The machine will blow the insulation to the required depth, as calculated in the earlier stage, to achieve the desired R-value.

It is important to note that the insulation should be dispersed and not compacted, as this will reduce its effectiveness.

During the installation of blown-in attic insulation, the contractor will also pay special attention to any areas that may require additional insulation, such as around vents, ducts, or light fixtures. These areas may require additional hand-placed insulation to ensure maximum effectiveness.

After the blown-in insulation has been blown in, the contractor will do a final check to ensure the insulation is evenly dispersed and has the right R-value. The contractor will also check that all air leaks have been sealed and that the ventilation system is properly installed.

Stage 5: Finish the Job

After installing the blown-in attic insulation, it is essential to finish the job by sealing any gaps or leaks in the attic. This will prevent air from escaping and help maintain the desired R-value. It is recommended to install an attic hatch cover to prevent heat loss through the attic access hatch.
