Cost of closed cell Spray Foam Insulation
Adversely, the closed cell spray foam’s density is 2lb per cubic foot. It’s R value is R6.5 per inch. It is used on walls, ceilings, roofs and under tabs. This type of insulation costs more than the open cell, but the high price is justified by its quality. The cost of insulation using this spray foam varies between $1.75 to $3 per square foot. When applied as should, this spray foam gives better results than any other method of insulation that is available in the market today. Having a look at the air exchange, this method gives an excellent insulation barrier. It is also really effective for repelling moisture from the inner walls of your house. Closed cell spray foam increases the ceiling’s strength, roof or wall structure with glue like tenacity.
The cost of spray foam insulation is also calculated per board, such that, open cell spray foam costs vary from $0.44 to $0.65 and the closed cell spray foam cost varies from $1 to $1.50. The average cost per professional installation of spray foam is $2,021 for the majority of companies in Toronto, Canada. This amount depends on whether the structure that is being insulated is newly constructed or renovated. To conclude, finished homes are not very suitable for insulation. However, they make excellent candidates for weatherization or an energy audit.
Measuring the thermal resistance (R-Value)
During the process of spray foam insulation or any other type of insulation, the R Value should necessarily be the basic part of your decision. However, it is also important to note that the loss or gain of heat can occur in many different ways, and as a result, measuring insulation through the R-Value alone is not always the right way.
Polyurethane foam spray does not necessarily guarantee prevention of all methods of heat transfer from taking place. Alternatively, you may want to consider radiation, heat conduction, air infiltration, convection and intrusion alongside the amount of moisture accumulation. All six of these mechanisms are the key factors of the effectiveness of the insulation.
DIY foam insulation costs
You can choose to install foam insulation by yourself using kits from brands of your choice. The average price of covering about 200 square feet with a foam insulation kit varies between $300 to $600, which is about two or three kits used. When you buy these kits, you will find a foam made up of two types of liquids referred to as Icynene, which are firstly heated and then pushed through a gun on the can. The installation cost might seem minimal when you decide to do it by yourself but if you are not experienced in installing spray foam, you may find it difficult to evenly spread the foam over a surface.
Failing to cover some spots or leaving some holes may lead to cold air getting into the structure. You can safely proceed with the insulation project if you intend to deal with small projects only such as foam insulation in a narrow space. Other large projects such as the attic, basement or garage should be left to certified insulation companies which can provide the proper equipment and have a respectful background. They will properly price the entire insulation project, whereas you on the other hand could incorrectly calculate the cost of the insulation project and end up losing more money in the process.
Insulation cost difference for Existing and new homes
There is a huge price difference when it comes to insulating a new home and insulating a relatively older home in Toronto. Insulating a recently constructed house is usually much easier because the insulating company can work effectively and make sure that the insulation is designed for optimum protection against heat transfer and sound, whereas installing spray foam insulation on an older home, specifically those that contain an existing insulation may cost more and require more time to install, which also increases the cost. Energy audits and weatherization are the most recommended alternatives for these kind of homes.
Cost of open cell Spray Foam Insulation
Open Cell spray foam’s density is of half an lb per cubic foot and an R-value of R3.5 to R3.6 per inch. The R value, also known as the thermal resistance, is determined by the foam density of the spray such that the higher the foam’s density, the higher the R value. R-value’s role in the insulation process is to show the resistance of the material to the heat flow. It is really important for this value to be high because this results in a greater resistance too. Open Cell foam spray has a lower density compared to that of its counterpart, the closed cell spray foam and it is not resistant to vapor. When used in attics and cool temperatures, it is advisable for the spray to be applied together with vapor retarder paint. The cost of the R6 foam varies between $2 to $7 per square foot.

Q: Where do we apply spray foam insulation?
A: Spray foam insulation is applicable on roofs, walls and on surfaces with contours and in corners with the aim of creating a tight air ceiling barrier. The two most used types of spray foams are made of polyurethane and are referred to as open cell and closed cell spray foam.
Q: Can I save money by choosing to insulate my property with spray foam?
A: When it comes to prices and costs, every investment in your house or property will certainly cost you a specific amount of money. Regardless, not each of these investments present you with a chance to save money. Saving yourself money that is spent on bills is actually possible with the use of spray foam insulation. These are some of the costs that should really be considered as future investments, especially for Toronto residents. Spray foam insulation costs depend on what type of spray foam is used and the amount that is applied. You can choose between insulating your whole house or just a part of it.
Spray foam insulation is considered as the best alternative to fiberglass insulation during construction or construction plans. The type of foam used in this insulation method is flexible and expandable and is easy to spray on existing wall cavities during construction or on roofs.
