Insulation questions, answered by experts

Each insulation type has its own R-value, so you’ll want to weigh the pros and cons of your materials when deciding which one will give you the best value. Energy.gov recommends you choose a pipe wrap that’s at least one inch thick. The International Code Council (ICC) suggests choosing a pipe material with an R-value of at least 3.

Yes, exposure to fiberglass insulation can cause harm to your skin and eyes. However, this typically refers to the fiberglass insulation that is mostly used in walls and attics. Fiberglass doors don’t pose risks for fiberglass exposure because they're fully encased in polymer cladding.

While more is seemingly always better when it comes to energy efficiency, your house does need some interaction with its environment. Adding too much insulation can affect your home's ability to breathe. Breathing simply means ventilating itself to reduce accumulated moisture within it. Too much insulation can physically block the venting ability or be enough to trap the moisture and damage the insulation or the house.

Garage door insulation can last anywhere from 20 to 100 years depending on the type of insulation. Cellulose has the shortest lifespan coming in at between 20 and 30 years, while spray foam, mineral wool, and fiberglass can last between 80 and 100 years with proper maintenance. 

Humidity plays a role in how long more susceptible insulation materials—like fiberglass—last. Once fiberglass batts reach the 15-year mark, you'll need to routinely inspect your insulation to ensure that it is in mint order.

Actually, condensation can mean that your windows are more energy efficient because the seal keeps cold air out and warm air in. In some cases, windows with poor seals can lead to more condensation, but they may allow the cold and warm air to mix and reduce condensation. If you’re worried about whether or not your windows are properly insulated, have a pro assess them.
