There is a lot of talk about insulation these days as people strive to make their homes more energy efficient. Here are some commonly asked questions:
Why is insulation necessary?
The U.S. Department of Energy (DOE) estimates that more than half of the energy costs of the average American home go toward heating or cooling. However, with proper insulation, the DOE states that a homeowner may be able to reduce their heating or cooling bill by 10 to 50 percent simply by increasing the amount of insulation in their home.
What does insulation do?
Air is constantly flowing through your home, even if your doors and windows are closed. It tends to move from warm areas toward cold areas and insulation restricts this movement. During cold weather, insulation prevents cold air from coming into your home through your ceilings and walls. During hot weather, it keeps cooler air inside your home and blocks it from migrating toward the outside.
What parts of my home should be insulated?
Basically, insulation should be installed in any barrier (wall or ceiling) that stands between cold air and warmer air, or heated spaces and unheated spaces. In most homes, the areas that should be insulated would be the ceiling, walls, basement and attic. Adding insulation to any crawl spaces or your garage can also save energy costs.
How much insulation should my home have?
Insulation is measured by its R-value or its resistance to heat flow. The higher the R number the greater its capacity for blocking air. The thickness of the insulation used, where it is installed, and how well it is installed will also determine the total R-value of the insulation in your home.
The DOE recommends certain minimum insulation values for homes based on the climate they are located in. For example, homes in mild climates may need only R-11 in walls and floors and R-19 in ceilings. Homes here in the north should have at least R-19 in the walls and R-38 to R-49 in the ceilings. Please note that these are only minimum recommendations. If you really want an energy efficient home, your contractor, or a firm such as ours, which specializes in insulation, can offer more detailed information. How your house is built, its age and location can also affect how much insulation you need in order to have a comfortable and energy-efficient home.
How do I tell if my home is insulated?
Homes built recently are most likely well insulated. However, homes built in the early 1960s or prior may not be insulated; if they are, the insulation may not be sufficient. Homes were not required to be insulated until the 1960s. Your local utility may provide a free energy audit that can help you determine if your home’s insulation is sufficient; local contractors or firms that specialize in insulation, such as ours, can also advise you.
What are some of the other benefits of insulation?
* Insulation keeps homes comfortable by making them warmer in winter and cooler in summer.
* Insulation reduces drafts.
* Insulation acts as a sound barrier, making your home quieter and less affected by outside noises.
* Insulation can help protect your home in a fire by adding a layer of fire retardation.
What kind of insulation should I choose?
There are numerous types available, but today we focus on what we feel is the best option available for energy efficiency, safety and comfort, that is spray foam insulation. We also offer an injection foam which is perfect for older homes lacking in insulation. You can visit our website at www.nickerson-remick.com and go to the Services page to learn more about our spray foam and injection foam options.Share post
