Low Cost Spray Foam Insulation in Toronto
Spray foam insulation is applied on walls, roofs and on surfaces with contours and in corners with the aim of creating an air tight ceiling barrier. The two most common types of spray foams are made from polyurethane and are referred to as open cell and closed cell spray foam.
When it comes to costs and prices, every investment if your house or premises will sure cost you a certain amount of money, but not all those investments presents you with a chance to save money. Saving some money that is spent on bills is very possible with the use of spray foam insulation. This are some of the costs that should be considered as future investments, especially for residents of Toronto. The cost of spray foam insulation depends on the the type of spray foam used and the amount that is applied. You can choose to insulate your whole house or just a part of it.
Spray foam insulation is a good alternative to fiberglass insulation during constructions or construction plans. The foam used in this insulation method is expandable and is easy to spray on existing wall cavities onto a roof or during construction.
Cost of Open Cell Spray Foam Insulation
Open Cell spray foam has a density of half an lb per cubic foot and an R-value of R3.5 to R3.6 per in. The R value, also referred to as the thermal resistance is determined by the foam density of the spray such that the higher the density of the foam, the higher the R value. The role of the R-value in the insulation process is to show the resistance of the material to the heat flow. It is important for this value to be high because this will result in a greater resistance too. Open Cell foam spray has a lower density as compared to that of it’s counterpart, the closed cell spray foam and it is not resistant to vapor. When used in the attic and cool temperatures, is is advisable that the spray be applied together with vapor retarding paint. The cost of the R6 foam ranges between $2 to $7 per square foot.
Cost of Closed Cell Spray Foam Insulation
On the other hand, the closed cell spray foam has a density of 2lb per cubic foot. It’s R value is R6.5 per in. It is used on ceilings, walls, roofs and under tabs. This type of insulation is the most expensive among the two, but the high price is justified by it’s quality. The cost of insulation using this spray foam ranges between $1.75 to $3 per square foot. When applied in the right way, this spray foam gives better results that any other method of insulation that is available in the market. Looking at the air exchange, this method of insulation gives an excellent barrier. It is also very effective for repelling moisture from the inner walls of the house. Closed cell spray foam increases the strength of the ceiling, roof or wall structure with glue like tenacity.
The cost of spray foam insulation can also be calculated per board such that, open cell spray foam costs ranges between $0.44 to $0.65 and the closed cell spray foam cost ranges between $1 to $1.50. The average cost for professional installation of spray foam is $2,021 for most companies in Toronto Canada. This amount varies depending on whether the structure being insulated is newly constructed or renovated. All in all, finished homes are not very good candidates for insulation. However, they make excellent candidates for an energy audit or weatherization.
Measuring the Thermal Resistance (R-Value)
During spay foam installation or any other type of insulation, the R Value should be the basic part of your decision. However, it is important to note that the loss or gain of heat can occur in many ways, therefore measuring insulation through the R-Value alone is not always the best way.
Spray form of polyurethane does not effectively guaranteed prevention of all methods of heat transfer from taking place. Instead, you should consider heat conduction, radiation, convection, air infiltration and intrusion and the amount of moisture accumulation. These six mechanisms are the key determiners of the effectiveness of the insulation.
DIY Foam Insulation Costs
You can choose to install foam insulation on your own using kits from the brand of your choice. The average price that you should budget to cover about 200 square feet with a foam insulation kit ranges between $300 to $600, which is about two or three kits. When you purchase these kits, you will find a foam made up of two liquids referred to as Icynene, which are heated then pushed through a gun on the can. The cost of installation might seem minimal when you choose to do it yourself but if you are an inexperienced installer, you will find it difficult to evenly spread the foam over a surface.
Missing some spots or leaving some holes can lead to cold air getting into the structure. You can proceed with the insulation project if you intend to deal with small projects such as installation of foam in a crawl space. Other large projects such as the basement, attic or garage should be lefts for professional insulation contractors who have the proper equipment and efficient knowledge background. They are in the best position to properly price the insulation project, whereas you could incorrectly budget for the insulation project and end up loosing more money in the process.
Insulation Cost Difference for Existing and New Homes
There is a very big price difference when it comes to insulating a new home versus insulating a relatively older home in Toronto. Insulating a newly constructed house is much easier because the insulating contractor can work effectively to ensure that the insulation is designed for optimum protection against utility costs, heat transfer and sound. On the other hand, installing spray foam insulation on a much older home especially those that contain an existing insulation can cost more and require more time to install. Weatherization and energy audit are the most recommended for such kind of homes.
