Overall, an average home can save 10 percent on cooling by insulating the attic. It's not immediately obvious that insulation can also help keep the house comfortable during the summer, but it's true. The right amount of insulation, combined with a well-sealed home, can save you an average of 15% on your annual heating and cooling costs. But to understand why attic insulation helps keep your home cool in the summer months, you must first know the ways in which a poorly insulated attic can cause your house to warm up.
Access to the attic is usually through one of these, but gaps around the attic door frame can allow air to enter. This is why it's essential to make sure that your attic is properly sealed and insulated. Aerosol foam insulation is relatively versatile and easy to apply and is often the best choice for homes with a certain degree of existing insulation. It can be difficult to determine exactly what type of insulation is best for your home, so it is always recommended that you contact a professional in your area to evaluate and estimate the attic and thus decide together which attic insulation material best suits your needs and those of your home. The R value is the ability of an insulating material to resist heat flow; the higher the r value, the greater the insulating power of the material.
The Department of Energy (DOE) has indicated that adding insulation to the attic is one of the most beneficial things a homeowner can do to improve the efficiency of their home. Of course, when it comes to improving the energy efficiency of your home, you don't have to limit yourself to attic insulation alone. Since attic insulation primarily helps keep winter heat inside, homes in colder climates need more insulation and, therefore, a higher R value. By acting as a way to keep heat inside, attic insulation helps keep you and your family cool and comfortable during summer months. Investing in adequate attic insulation will help make your home more comfortable while also saving you money on energy costs.
