Most of the energy costs spent to keep a North 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?
Are You Trying To Find Interior Wall Insulation Contractor For Your North Toronto House?
Although spray foam insulation as we know it today truly emerged in the 1980s around the North 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.

During the 1940s, polyurethane polymers were used primarily in military and aviation applications. The production of war machines for the World War II conflict drove most of the applications of these high-grade plastic polymers for the duration of the war.
It was not until the 1950s that polyurethane began to be used in home insulation. It was the invention of the "Blendometer" that allowed for expansion of polyurethane application to the home insulation realm. The Blendometer was the first machine able to mix components for the creation of polyurethane foam and was created by Walter Baughman in 1953.
The 1980s and early 1990s saw a great deal of controversy within the spray foam insulation industry as different marketing schemes from various companies promoted the benefits of closed verses open foam insulation and as some companies tried to market water blown foam application processes.
Though there has been much debate within the industry, R-value standards, used as a measure of determining energy efficiency, have cleared up much of the controversy. R-value ratings clearly define closed foam as the most effective means of making a home as energy efficient as possible.
Closed cell spray foam has additionally been added to the list of building requirements for making homes in hurricane and earthquake zones more structurally sound. The improved stability of homes insulated with spray foam technology makes the use of spray foam a smart move for any homeowner regardless of geographic location.
What is Insulation, Why Do We Have it and How Does it Work?
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.
