Attic Insulation and Air Sealing

The Truth About Attics and Insulation

Most of us know that warm air rises. In a house, that means warm air is headed to the ceilings of the uppermost floor. If those ceilings are cold, because the attic above them is poorly insulated, then the warm air isn’t going to stay warm for long, and your home is going to be less comfortable and more expensive to heat.

You think the first step is to call the insulation company and add insulation to the attic, right?

Wrong! While adding insulation to your attic is one of the most important pieces of the home energy puzzle, you should not do it until you’ve completed some key preparatory steps. What these steps are depends on your house, but they may include:

  • Repairing and eliminating the source of structural damage caused by roof leaks, insects or other factors;
  • Reducing moisture in the attic caused by air leaks in the house and duct systems;
  • Removing debris and hazardous substances, including asbestos, mold, animal droppings;
  • Inspecting and upgrading, if necessary, old plumbing, electrical and duct systems, which may have safety or functional limits;
  • Adding baffles and roof vents to ensure that the new insulation stays dry and free from mold and mildew.

Adding insulation in an attic without having addressed these conditions not only hides problems, but can even make them worse, and more expensive to repair or upgrade later. And when the repairs finally get done, the existing insulation gets damaged in the process.

So remember, insulation isn’t the first thing to do in your attic. It’s the last. If you hire Vesta to upgrade your attic, you should never have to go up there again, for as long as you own your house. Now isn’t that a nice thought?
