Why you should retrofit your home with foam insulation in Toronto

The majority of homes in North America especially Toronto are insulated with an air-use insulator,  either fiberglass, or cellulose. Dead air and the principles of convection and advection (R-factor) are how these materials are expected to insulate our homes and buildings. The issue lies in that the thermal dynamics working against the envelope of the building are more powerful and intricate than the air use insulator can control. For example, the R-30 loose fill in the majority of attics; in just a couple of hours, radiant heat can build up in your attic to 60 degrees celsius and completely pass through the R-30 and start heating up your house while jacking up the power bill, this is especially true if you have an HVAC system where the ducts and vents are in the attic. Your house should be cooling down when the sun sets, but the air-use insulator will retain the heat and not allow for the house to cool down for several hours.

Conventional insulation really becomes energy hungry in the winter time. When indoor air is heated and the house becomes like a hot air balloon. When the air is heated, it wants to rise and pass through the loose blown in insulation in your attic flooring. When this rise of air occurs, the mass of air takes with it temperature and moisture in the envelope of the house and moves it to the attic. Air mass expansion in the summer months, creates a required pressure release through bents in the attic, this pressure has to be equalized  so that it doesn’t push it into the living area. These vents allow for the heated air to be pushed through allowing for newer cooler air to replace it and start the process over again.

It’s always a good idea to have a look at where the money will be spent, and where it will be best spent before retrofitting your home. Make sure to contact the right insulation contractors Toronto has to offer. Up to %35 of energy is either lost or kept through the roof of the house. Crawl spaces of a home can contribute up to %30 in energy cost and the windows, doors and walls make up the rest. Stop all radiant energy fro entering the building by spraying open cell polyurethane foam under the or against the roof deck. In the hot and humid summer months, humidity is kept from entering the house. Without radiant energy, there is no expanding air mass. Without expanding air mass, vents aren’t needed and by not needing vents, there is a stop of temperature fluctuations in the winter months and your HVAC system doesn’t  have to work overtime.

The roof should be sprayed as it is the largest contributor of energy loss in the envelope of the whole house, followed by the crawl space. Trying to re-insulate walls is a bit tricky and has little payback. Always contact the most reliable spray foam company when you are heating or cool in the air inside of your home, it’s because you retrying to create a different climate inside your home compared to what’s going on outside. When you install open cel polyurethane foam, it eases the burden on you HVAC system which saves you money in the end. You re-coup the initial investment after 3-7 years of energy savings.


Upgrading Your Home with Spray in Insulation

Spray In Insulation is a cheap alternative method to traditional building insulation. It works by having an expanding form from a mixture of two components. The form is mostly made from Polyol resin and Isocynate after combining at the tip of the gun.

The method is very important in keeping your home cool in the summer and warm in the winter. This is because of the rising energy bills when any source of energy is used. Thus, when building or renovating a bought house, you can improve its comfort by using this affordable method.

Where to Insulate

You should add insulation in the following areas Attic, walls, floors, basement, and crawlspace. In addition to that, this will be the cheapest way to improve your home’s energy efficiency. However, you can inquire about crawl space and basement insulation from your contractors.



Materials Used for Insulation

Insulation is made from a number of different materials. These come in four different types namely: loose-fill, rolls and batts, rigid foam, foam-in-place. Blankets or rolls and batts are made from mineral fibers like fiberglass and the rock wool. These flexible materials come in widths suited to standard spacing of wall studs and floor joists or attic: 2 inch by 4-inch wall can take R-13 or R-15 products; 2 inch by 6-inch walls can use R-19 and R-21 batts.

Loose-Fill insulation is mainly made as loose fibers or fiber pellets from fiberglass, rock wool, or cellulose. This material is blown into the spaces by special pneumatic equipment. The material adapts easily to odd-sized building cavities and attics with wires, ducts, and pipes. This makes it suitable for use in areas where other types of insulation fail to work well.

Rigid Foam Insulation is very effective in exterior for basement wall sheathing or other special applications like attic hatches. Foam insulation R-values have range of between R-4 to R-6.5 per inch of thickness. Moreover, this form of insulation material is 2 times greater than other insulating materials.

Foam-In-Place Insulation is mainly used to insulate and reduce air leakage. The material is blown into walls, under floors or on attic surfaces. Thus, you can use small-pressurized cans to block small holes and cracks. These can be like the ones on doors, windows frames, plumbing and electrical penetrations.

Tips to Consider before Insulation

Here are some tips given by the local insulation contractor, , about what you should consider before insulating your home. There are key factors to consider before you think of doing insulation in your home. You should first consider the climate of our home area, home design and budget. This will help you in choosing the best insulation most suitable for your home.

You should also consider using higher R-value insulation like spray foam on the exterior walls and in cathedral ceilings. This ensures you achieve more insulation with reduced thickness. You should as well consider fixing attic air barriers along the attic eave. This helps in reducing summer cooling bills as it ensures proper airflow.

You should consider whether the fixture next to where you want to place the insulation is insulation contact rated. This helps in avoiding a fire danger. You should finally follow the installation instructions from the manufacturer. In this regard, you should always wear genuine protective gear when installing.


You will end up saving more money in most climates when you install a combination of insulative sheathing and cavity. This can be better done if the installation is done when building a new home or addition.

Moreover, you can reduce exterior wall leaks by fastening the joints of exterior sheathing and closing the gaps on exterior walls. These helps in reducing the amount of energy lost through the wood frames.
