Most of the energy costs spent to keep a Humber Bay 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 Humber Bay 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 Much Attic Insulation is Enough?
A number of companies are offering DIY polyurethane foam insulation kits for home use. TigerFoam, Handi Foam from FomoFoam, Foam It Green DIY Kits are some of the top brands available online. Tiger Foam offers both Slow Rise and Fast Rise formulations. The Slow Rise is for filling wall cavities and other hidden closed-off spaces in the house. The Fast Rise foam is more suitable for spraying surfaces.
The DIY kits come complete with all the equipment needed to apply the spray foam-nozzles, tank, hose and tips. They also have careful step-by-step instructions that need to be followed in order to the job safely and also for best results.
Apart from insulation the polyurethane foam also acts as a sound barrier. It is moisture resistant and hence prevents mold in the wall cavities and wall surfaces. The excellent insulation capacity of the foam results in the complete cut-off of air transfer from and into the house. Retention of temperature of the house is excellent in homes insulated using polyurethane foam insulation kits. You will save a ton of money in utility bills and the insulation costs will soon paid for.
The Advantages of Home Insulation
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.
- With the cold season upon us, we thought it is important to write about insulation in the home. It's something that most people never give any thought to, but hidden in the walls of your home is an added layer of protection from the outdoor elements. One recent report by the North American Insulation Manufacturers Association stated that approximately 90 percent of all existing homes lack enough insulation. Jonathan Levy, a professor of Environmental Health at Boston University School of Public Health stated, "If all U.S. homes were fitted with insulation based on the 2012 International Energy Conservation Code (IECC), residential electricity use nationwide would drop by about 5% and natural gas use by more than 10%."
Choosing the right type of insulation for your home will depend on your local climate, home design, how it is used and your budget. If you have an attic, crawlspace or basement, then adding additional insulation to the space can be a cost-effective way to save more on your energy bills.
Types of Insulation
While there are a variety of materials that insulation can be made from, it typically is available in four different types:
Foam-in-Place: Foam-in-place is an easy do-it-yourself project for homeowners that can be done with a small pressurized can. It is typically used to fill in small holes and cracks around door frames, windows, plumbing or electrical.
Loose-Fill: Loose-fill is primarily made up of rock wool, fiberglass or cellulose that are in the form of fiber pellets or loose fibers. Special pneumatic equipment is utilized to blow the loose-fill insulation into place.
Rigid Foam: Typically the most expensive of all insulation types, rigid foam can be an effective option and also provides greater insulation. This type of insulation is most commonly used for special applications as well as interior or exterior wall sheathing.
Rolls and Batts: Also known as blankets. This type of insulation is made from mineral fibers and is available in sizes that fit the standard spacing of wall studs, attic joists or floor joists.
What is the R-Value?
The R-value is a measurement to determine the insulation's resistance to heat flow. The recommended 'R-value' will vary from one home to the next as climates and heating/cooling systems differ. R-values range from zero to forty (sometimes even higher). The higher that the R-value is, the greater the insulating effectiveness it provides. The United States Department of Energy estimates that nearly half of a typical home's utility bills are spent on cooling and heating. Ensuring that air is not leaking into your home through windows, doors and other openings can significantly help cut costs on utilities. Additional benefits of a well-insulated home include better humidity control, less dust, pollen and insects as well as noise reduction. When all of the gaps, leaks and holes are added together in a typical home's envelope, it is the equivalent of having a window open each day of the year. If you are curious about how much insulation your home needs you can look it up on the U.S. Department of Energy Recommended Total R-Values for New Wood-Framed Houses here (http://www.energy.gov/energysaver/tips-insulation). Additionally, if you have an attic in your home, you may be able to save more money on energy bills. The U.S. Department of Energy estimates that between 10 to 50 percent can be saved off of a heating bill just by having a properly insulated attic. It's worth having a professional insulation company come and look at your home to make sure that it does have the proper insulation needed. Energy auditors can also perform this task as well as provide you with other great tips to save energy. With the cold season rolling in take the time to make sure your home has the correct insulation.
