Attic Insulation Best Methods

Proper attic insulation is key to a Milwaukee, WI, energy-efficient home. For most climates, the bare minimum is 13-14 inches of fiberglass batts, or R-30. But adding more will boost your return on investment.

To get the most out of your insulation, start by identifying and sealing air leaks. This prevents unwanted airflow that ruins the effectiveness of your new insulation. Foam sealants, caulking, weather stripping, and other products will help you keep your house air-tight.

Fiberglass batts are the most popular type of attic insulation. They are inexpensive and easy to install. They provide good energy efficiency, sound control, and air quality protection. They are available in faced (with a paper backing that faces your living space) or unfaced (without a facing) options.

Improve Attic Insulation Performance

Blown-in (loose fill) cellulose and fiberglass insulation are also readily available in attic spaces. Both are made from recycled materials, and cellulose has the added benefit of being fire-resistant. They can be installed quickly by a professional. Blown-in insulation is effective at reducing noise transmission, and provides more comprehensive coverage than fiberglass batts. However, it can settle over time, reducing its R-value. Also, cellulose can absorb moisture, which may lead to mold and mildew.

Mineral wool is an eco-friendly alternative to fiberglass insulation. It’s made from shredded, treated denim fibers and is treated with borate for fire resistance. It can be used for attics, walls, and floors. It reduces heat gain, lowers cooling bills, and is effective in hot climates. However, it may not be as effective in cold climates, and can absorb moisture which will rot the batting. It is also a bit more expensive than fiberglass insulation.
