Insulation questions, answered by experts

Spray foam has superior sealing properties, moisture resistance, and soundproofing capabilities compared to traditional insulation.

A DIY blown-in insulation project in a typical attic should take you no more than a week to complete. Experienced homeowners can blow an entire attic in one or two days.

In most cases, the building code in your location will determine the minimum amount, in R-value, required for your home's walls, attic, and other spaces. For attics, the minimum R-value amounts start at R30 in the south, R38 in mild climate locations, and R49 in northern states and cold western areas.

Whether plaster walls should be insulated depends on whether the walls are at particular risk of moisture problems. In many cases, you can insulate plaster walls, while in others, it's a poor decision because of the lack of a vapor barrier. Choose a reputable insulation contractor to help you decide if and how to proceed to increase your home's energy efficiency.

Exposed ductwork can sweat just like ductwork placed behind walls, sometimes even more so. Ductwork sweats—like a cold drink on a hot day—because of a temperature imbalance between the air in the duct and the air in the room. In a crawl space or wall, this temperature can equalize faster due to the small space but in lofts and open rooms, that wouldn’t happen as quickly. Many people insulate their ducts for this reason.
