A well-insulated attic is a home’s best defense against high energy bills and comfort problems caused by air leakage. Adding insulation to an attic has been proven to pay for itself in a few years by saving on cooling costs in the summer and heating expenses in the winter. It is important to pick the right type of insulation for your specific home. There are a number of different options on the market and each type has its pros and cons. This article focuses on three of the most popular types of attic insulation: fiberglass batts, fiberglass rolls, and loose-fill insulation.
Each type of attic insulation has its own R-value rating which indicates how effectively it keeps the flow of heat in and out of your home. The higher the R-value, the better the insulation will work.
Choosing the best attic insulation indiana for your particular situation requires careful consideration of the R-value requirement for your home, the climate you live in, and the amount of sunlight your house receives. A qualified professional can help you select the proper insulation for your attic.
Fiberglass is a common choice for insulating attics because it is inexpensive and has a decent R-value. It also comes in a variety of thicknesses, which allows homeowners to customize their attic’s level of insulation. However, fiberglass insulation is not moisture-resistant and will lose its R-value if it becomes damp or wet. It can be dangerous to touch and requires special precautions when removing from attics. In addition, it’s flammable and must be installed over a vapor barrier to prevent fires.
Another attic insulation option is fiberglass rolls, which are similar to fiberglass batts but come in longer segments that can be cut to fit between joists. This makes it easier for DIYers to install. Fiberglass rolls are also cheaper than blown-in insulation and can be installed without a vapor barrier. However, these rolls must be cut to size and gaps can develop between them if not properly installed.
Loose-fill cellulose or fiberglass insulation is a great choice for homes in colder climates, which require more effective insulation. This type of insulation is blown into the attic using a blower and can be applied to hard-to-reach areas. Its effectiveness is boosted by covering gaps with duct tape before installing it.
Spray foam is a highly effective attic insulation that is available in many different R-values. It provides a tight seal and is made from recycled materials. It is not a good choice for attics with HVAC ducts or plumbing pipes, and it can cause damage to attic decking or rafters. If you are planning to install spray foam, consider hiring a professional. Whether you choose a fiberglass, roll, or loose-fill attic insulation, it is important to prepare your attic before installation by sealing air leakage sites and repairing any damage. This will ensure your new insulation is as efficient as possible.
