Insulation questions, answered by experts

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.

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.

Sometimes you may be able to leave the bags with your regular trash. However, that’s not always the case. Call your local waste management prior to starting the removal and ask about the proper ways to recycle or dispose of removed insulation. In many cases, your town or municipality has a designated dumpster for building waste.

Spray foam insulation doesn’t do well around heat sources. Therefore, You can use spray foam insulation to seal around HVAC boots that penetrate through the drywalls or around where wrapped ducts connect to the boots, but we don’t recommend using spray foam insulation to encapsulate your air ducts. Spray foam insulation on air ducts is also less effective compared to duct wraps.

Yes, you can install insulation over ductwork, and doing so can save you money. Without insulation, the HVAC unit must work harder to force warm or cool air around the home, and once the air reaches the vent, it may not be the correct temperature. Insulating HVAC ducts makes your system work more efficiently, saving you money on heating and cooling bills.
