Insulation questions, answered by experts

A radiant barrier is worth the money if you live in a hot, sunny climate. Over time, you should be able to recoup your investment through lower energy bills. Though it can vary depending on where you live and the type of barrier you choose, you might be able to reduce your electric bill by as much as 5% to 10% after installing a radiant barrier.

The type of insulation you need in your home depends on your location, the installation site, and your region’s climate. According to Energy Star, insulation in homes in the Southern United States should have an R-value of between R30 and R60 in attics and R13 to R25 in the floors and walls; homes in moderate climates require R values of R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require an R value of R49 to R60 in attics and R25 to R30 in floors and walls.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

Glass fibers are often used in HEPA filters because of their high efficiency, durability, and thermal stability. Some HEPA filters are made with synthetic fibers, but they may not be as effective. While there is some fiberglass shedding, as long as the HEPA filter is intact and not cut open, the amount of fiberglass released by a HEPA filter is well below the breathable particulate matter.

The cost of installing spray foam insulation is $2,760 on average, but this cost can be as low as $650 or as high as $7,700. The main cost factor is the size of the insulated area and the type of spray foam insulation. 

Polyurethane spray foam costs between $0.44 and $1.50 per board foot, where a board foot is equal to the volume of a one-foot length of a board. More expensive options, like soybean or vegetable oil spray foam, range from $1.50 to $3.00 per board foot.
