Most of the energy costs spent to keep a Toronto home warm in the winter and cool in the summer end up leaving through the attic. In the summer, the sun’s heat pours in through the attic and in the winter, warm air rises past the ceiling and out of the home. Saving on energy costs starts in the attic, but how much insulation is enough?

Although spray foam insulation as we know it today truly emerged in the 1980s around the Toronto area, spray foam actually has its roots several decades further in the past, beginning with the development of polyurethane foam in the 1940s by Otto Bayer. Otto Bayer, an industrial chemist, actually began working with polyurethane in Germany during the late 1930s. This technology was brought to the United States in the early 1940s by David Eynon, the president of Mobay, a war effort conglomerate created from the partnering of two chemical industry giants, Monsanto and the Bayer Corporation.
How To Install Blown In Attic Insulation
What is Spray Foam Insulation?:
It's a form of insulation, which is sprayed over an area you wish to insulate, instead of the conventional way of placing some sort of insulation in the wall cavity. When it is sprayed it rapidly expands and fills in every single void it can, creating an almost perfectly sealed space.
What are the advantages of using Spray Foam Insulation?:
By expanding and filling ever crack and void it provides complete sealing, preventing air from leaking, which is still in effect with other insulations. It can be placed in any area without having to remove existing tubing, electrical wires or pipes of any kind. It is water repellent and allows moisture to leave from the walls. Mold cannot grow on it. It also prevents the development of mold, which is due to humid air. It is an effective way of reducing outside noises. Also, Spray Foam Insulation has a low flammability. It can be used as an effective way of insulating your boat. It can be used in small areas.
Is it environmentally friendly?:
Many organizations have rated spray foam insulation as one of the greenest methods of insulation with the most attention going to icynene. Most spray foam insulations do not contain HCFC's, CFC's or formaldehyde. They are relatively safe for individuals with respiratory problems such as asthma. So the answer to the question is yes it is environmentally friendly.
Spray Foam Material Handling and Storage
Movement of air in and out of a home can be a leading cause of escalated energy bills. Air can enter your house through holes, cracks and crevices. You can stop unconditioned air from entering your home and indoor conditioned air from escaping outside by adding an advanced insulation system to achieve optimal building performance.
A small science lesson about insulation:
Heat moves from warmer areas to colder areas. This is the single basic principle on which the idea of insulation is based. On hot days heat tries to get inside your house and on cold days the heat tries to escape. Insulation seeks to minimise this ebb and flow of temperature by slowing the process.
Unfortunately no matter how good your home insulation is, any building always needs a constant supply from a heat generating source to maintain a steady temperature. Of course however, if you have good insulation then you will need much less heat and thus a lot less energy to achieve the same effect.
Most of us learned in GCSE science about conduction convection and radiation.
Here is a brief summary of each to refresh every ones memory.
o Distance between surfaces
o The emissive of the surfaces (shiny and light/matt and dark)
o Temperature differences between receiving and radiating surfaces
The application of thermal insulation does not have the effect of generating heat in your house. It is still always the rule that you will have to supply heat from an inside source. There may be a rise in temperature inside the building after the installation of insulation but that will be down to the better performance and energy saving properties of better house insulation.
