Most of the energy costs spent to keep a Markham 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 Home Insulation Contractors For Your Markham House?
Although spray foam insulation as we know it today truly emerged in the 1980s around the Markham 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.
- 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.
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.
Insulation at home helps in saving energy and reducing utility bills. It makes the house more comfortable. Insulation at home not only helps in keeping the house cool in summer and warm in winter but it also prevents damage from leaking water and provides a good thermal resistance. Insulation is very useful to keep the temperature of the house as outdoor temperature.
By using insulation, the cost spent in cooling and heating the home can be reduced to a great extent. There should always be sufficient insulation at home to protect the house from air leakage, water leakage etc. R value, also known as thermal resistance is used to compute the insulation resistance. It shall be installed between the heated and unheated space.
There are many types of home insulation available. All insulation has pros and cons. They are mainly differentiated based on the material used for the insulation. They can be distinguished into Plastic foam, rigid board, reflective, loose fill, batts and blankets and blown in insulation etc. Batts and blankets insulation can be performed by the homeowner himself. No professional is required for this type of insulation. They are easily affordable and the material like blankets and batt strips are easily available in the market. Batts and Blankets insulation can be performed with the help of materials like Fiberglass, Mineral wool, plastic, concrete block, polystyrene fiber etc.
Insulation can be performed at home in attics, on ceilings, exterior walls and garages and storage areas for proper ventilation and thermal resistance. Insulation must be performed either by professionals or proper care must be taken while installing them. Air and water leaks must be thoroughly checked before installing the insulation as moisture can dampen the efficiency of insulation or insulation may mask them. It must be checked that electrical equipment and fixtures are not getting touched by the insulation. Also some insulation can cause allergies to the skin and may cause respiratory problems so proper care must be taken while installing them.
