Most homes, even newer ones, simply don’t have enough insulation. The minimum insulation levels required by building codes don’t come close to protecting your living space from temperature extremes. An estimated 35 percent of heat loss is through the walls. The better insulated your home is the less heat you will be losing, meaning you do not need to run your heating as much (saving you money!).
Insulating your walls will help reduce your energy consumption and lower your fuel bills. Insulation can also help alleviate damp, making it a healthier home to live in.
There’s no getting around it: If your house is in a cold climate, keeping it warm in winter is expensive. The Department of Energy predicts that prices for natural gas and heating oil will rise again this winter compared with last—and that’s after a year in which heating-oil prices rose sharply in most parts of the country.
Sure, you can dial down the thermostat and get used to wearing bulky sweaters indoors to cut costs. But if you’ve got an unfinished attic, giving it proper insulation is one of the simplest ways to keep a lid on your heating bill this season.
Insulation saves money, increases home comfort, and protects the environment by reducing energy use. According to the U.S. Department of Energy (DOE), the typical U.S. family spends close to $1,500 each year on energy bills. DOE statistics show that, typically, 44% of a homeowner’s utility bill goes for heating and cooling costs. DOE states that homeowners may be able to reduce their energy bills from 10% to 50% by taking certain steps. One of the major steps is increasing the amount of thermal insulation in their existing homes or purchasing additional insulation when buying new homes.
R-value measures insulation’s resistance to heat flow. It can also be referred to as “thermal resistance.” The higher the R-value, the greater the insulating power. All materials having the same R-value, regardless of type, thickness, or weight, are equal in insulating power. The R-value of different insulating materials must be based on test methods established by the American Society of Testing and Materials (ASTM). Don’t forget that R-values are determined by material type, thickness, and installed weight per square foot, not by thickness alone. Insulation helps keep your home cool during the summer months and warm during the winter months.
Proper installation is essential for insulation to perform properly. Knowledge of vapor retarders, air infiltration, ventilation, recessed lighting, and water pipes are just a few of the areas critical to installation techniques. Professional insulation contractors have access to a wide variety of training, are familiar with local codes and regulations, and can offer guidance about the type and amount of insulation to be used.
Yes. Insulation is an efficient way to reduce unwanted sound, and it is commonly used to provide a more comfortable and quieter interior environment. Insulation effectively reduces noise transmission through floors and through interior and exterior walls. A professional insulation contractor can help you select the proper insulation for your needs.
Fiberglass – This type of insulation traps air bubbles and creates an insulation effect that escalates, slowing heat exchange between surfaces.
Spray Foam – This is a polymer that expands to nearly 100 times its original volume, and then hardens into a solid. This allows for much more coverage and is more of an automated process than fiberglass.
What’s the point of insulating every nook and cranny around the house just to let air seep in and out of the garage, especially since these spaces are known for fluctuating temperatures: they’re steamy in the summer and freezing in the winter?
Engineering studies have shown that replacing a non-insulated garage door with an insulated one can reduce heat loss through the garage by more than 70%. Even if your garage is unheated that could mean a garage that’s warmer by as much as 20 degrees Fahrenheit
According to the U.S. Department of Energy, homeowners should insulate crawl spaces and unheated garages. Although they aren’t living spaces in your home, they are important when it comes to helping you save on your energy bills.
Crawl space insulation (and sealing) can help maintain your entire home’s energy efficiency. Without insulation, heat and cool air are easily lost—in fact, crawl spaces that aren’t insulated can be huge sources of energy loss.
