Attic insulation is a key energy-saving tool that prevents air leaks and drafts from entering your home. These issues can cause temperature fluctuations in your home, which will affect the comfort of your living space and increase energy costs.
It can also reduce the growth of mold, mildew and other microorganisms that could cause illness or other health problems. Moreover, it can help to eliminate air pollutants that are harmful to your health and the environment.
Besides saving you money, attic insulation can help to increase the value of your home as well. In addition, the insulation will help to prevent ice dams from forming on your roof during winter.
The first step in determining whether your attic needs to be insulated is to perform an inspection. Look for cracks or holes that can let in cold or hot air and any signs of water damage.
Insulation is available in several materials, including fiberglass, cellulose, liquid polyurethane and polystyrene. It comes in rolls or batts and can be installed by an experienced contractor.
Foil is another option that can be blown into your attic space using a blower or dropped in by hand. It has a reflective barrier that prevents heat transfer by creating a pocket of air that slows down the speed at which your attic’s temperatures can change.
Fiberglass is a type of cellulose that can be blown into your attic, or it can be purchased as rolls of batting. It has a lower R-value than cellulose, but it can be easier to install and is cheaper than cellulose.
Cellulose has an R-value of 2.2 to 3.8 per inch and is available in a variety of thicknesses and materials. It is the most effective material, but it can lose 20% of its R-value over time if it is exposed to moisture.
Loose-fill insulation can also be blown into your attic space and is available in a variety of materials, including fiberglass, cellulose and mineral wool. It can be used to fill voids that are difficult to reach with a blower and is available in a variety of thicknesses.
The installation process is simple. Start from the perimeter of your attic and work your way to the entry, making sure to cover all vents and soffits that can allow moisture to enter the attic.
If your attic does not have proper insulation, it is likely to be a nesting spot for pests like rodents and birds. This can be an expensive problem since they can damage the insulation and leave waste products behind.
Spray foam is a versatile insulator that is often paired with blanket insulation. It is easy to apply, seals gaps in existing walls, and can make the installation of loose-fill or blown-in insulation much easier.
The attic insulation industry has made strides in recent years, and if you are looking to save money on your energy bills and improve the energy efficiency of your home, it may be time to consider adding attic insulation. It can add significantly to the overall value of your home, and it will provide a great deal of peace of mind for your family.
