Green Investment Fund Ontario

Ontario has committed about $325 million in their Green Investment Fund to finance projects in Ontario that will help fight climate change, create jobs and grow the economy. All these plans are to help secure a clean, prosperous, and healthy low-carbon future. This project will:

• Homeowners use less energy
• Retrofit social developments
• Support electric vehicle charging stations across Ontario

This project will help about 37,000 homeowners in Ontario conduct audits to identify energy-saving opportunities to complete retrofits such as replacing water heaters and furnaces and upgrading their attic insulation. These energy-saving retrofits will help consumers save money on their energy bills. Ontario homeowners can apply for these rebate programs to help cut costs when upgrading their home insulation.

Union Gas Heating System Rebate- Additional Rebate

The Union Gas Heating Rebate Program helps homeowners save $1000 through rebates when they buy an upgraded furnace or boiler. Provided you buy a qualifying model, this program will get you a rebate of $1,000. After you have done your home assessment and also made an energy-saving upgrade (furnace or boiler), you are eligible for more upgrades on the same program. Homeowners can get an insulation rebate after participating in the Union Gas Heat System Rebate program. The money you will get on this largely depends on the resulting R-value of the insulation and where you choose to improve your insulation thermal resistance. This program offers $250 to $1750 in insulation rebates, but only after you have qualified for a heating system upgrade from Union Gas. There are several other rebate programs offered to Ontario residents for:

• Upgrading heating equipment
• First-time Homeowners for high efficiency homes and reduction of rates
• Elderly and disabled Homeowners

• Consult a contractor who has experience with government rebates to help you get the best value out of these rebate programs.

Among many of the programs, Attic and Basement insulation improvements are among the most heavily incentivized upgrades your home could consider.

Measuring Insulation in Attic

What is the adequate amount of Insulation in an attic?

Further Insulating the attic space is an optimal solution to enhance your living space comfortable and, more importantly, to reduce energy bills.

When it comes to upgrading your attic insulation, more is not always better, and there is such a thing as too much insulation. Call Canada Energy Solution for professional attic insulation assessment and services all across Ontario.

• The temperature in your attic should be similar to that of the air right outside.
• air should be circulating through your attic. This keeps the attic from developing excess moisture and mold.
• Too much insulation without installing baffle rafters and airways can mean that your moisture is getting trapped inside the attic with insufficient ventilation. This particular attic may have excessive moisture in a very short period of time. Hence we need to avoid installing insulation material close to the area where the ceiling meets the wall and rafters. Blocking these mentioned critical areas will block the free flow of air and initiate grounds for mildew and mold to thrive. The air flow occurring at that rafter space is essential for the overall health of the attic as well as the quality of the air in the main living spaces. If there is to find mildew, it can be considered as a sign that there is inadequate air circulation in comparison to the amount of insulation.

Fiberglass Batt Insulation

Insulation batts usually have a massive surface area to space ratio. This means that when spread onto an attic’s surface, it insulates the space by diffusing the cold or warm air that would be regularly  passing through it, hence creating a thermal barrier. In Ontario Homes batts are most often used as a wall insulation however many homes also have used batts inside the attics for improving attic insulation resistance. However, it is not usually the best choice to put inside an attic as thermal insulation when it comes to overall thermal insulation strength and volumetric density.

R-value : Measuring How well Insulated a surface is

Batt insulation comes in varying R-values depending on the space in the application.

Example:

• R-14 batt is available to fit in a 2-by-4 stud for walls
• R-30 fits areas with a 2-by-10 ceiling and floor joist.
• Some manufacturers offer variants that provide satisfactory R-values while occupying smaller spaces.
• Installing more batts into your attic does not simply improve the overall r-value.
• Picking the right type of insulation for adequate application is essential.

Does Improving the Attic Insulation Save Money?

Ontario Home energy Insulation Attic

The cost of attic insulation upgrade or renewal may seem significant at the beginning. A standard Ontario contractor may charge anywhere between $1.00 to $2.50 per square ft based on the job at hand. The investment is almost always completely worth it.

Attic insulation is a practical home improvement project and must be met with planning and adequate budgeting,  here are a few reasons why:

Reduce energy bills

Investing in high-quality attic insulation improvement achieving a high R-value done by reputable contractors may save up to $1,200 in annual heating and cooling costs. In a conventional home, the attic is most likely vented to the exterior of the house and insulated with porous material that allows heat to escape winter and enter during the summer. The wrong Installation of insulating material to the upper trusses will drastically reduce the amount of necessary airflow within the home. By improving attic insulation, uneven temperatures that make the air conditioning system actively work all day can be mitigated. With reduced energy usage, the carbon footprint is also reduced, and relative environmental conservation is achieved.

Comfort Improvement

In addition to lowering overall annual energy bills, uneven temperatures between the floors make the home uncomfortable to live in, especially in the peak of summer and winter climate in Ontario. Insulation materials reduce heat loss hence the degree of the unwanted temperature difference (less reduction <cold> in winter and less increase <hot> in summer)  as a result, the home feels more comfortable to live in.

During allergy seasons, adequate insulation can reduce the amount of dust, pollen, and dirt that enters your home as it properly air seals the attic. This reduces the total amount of unwanted particulate matter coming in.

Increase property resale value

If the sales of the property are on the horizon, the selling price can be higher when the attic is well insulated. Buyers are willing to invest extra amounts for a house that is deemed ultimately more comfortable and has lower average expenses on the energy bills, which means that one may get all the initial investment used to optimally insulate the attic back upon the final sale of the property.
