To keep the air quality of your home healthy, prevent damage to your attic and roof, and keep your HVAC system running cost-efficiently, it’s important to maintain an air barrier between the living space of the home and the attic. Simply put, everything works better when attic air is kept out of the house and house air is kept out of the attic. Why? Let’s start with keeping attic air where it belongs. If you’ve ever ventured into the attic, especially during the warmer months, you know that attic air can be outright nasty. It often contains dust particles and other contaminants — contaminants that can cause health problems for the home’s occupants. The less attic air that enters your home’s living spaces, the better.
Just as important, we want to keep living space air out of the attic. Living space air can can be filled with water vapor. When that air is exposed to colder attic temperatures, the vapor gas condenses into water droplets that can potentially cause roof rot and mold growth (unfortunately, mold is an all-too-common attic contaminant). Living space air naturally tries to move up into the attic, especially in the winter, because of the “stack effect.” Heated air rises and expands. As air heats up, its molecules are pushed farther away, making it lighter (that’s why hot air balloons float). The air pushes upward against the attic floor. If there is a way for the air to find its way in, it will. Air leakage into the attic stresses your HVAC system, increasing your heating and cooling bills. There are a number of possible sources of air leaks, but attic hatches are at the top of the list. More often than not, attic hatches are unsealed and have gaps that allow for unwanted air movement. There is an easy solution for this: Attic stairway covers.
The homeowner mentioned to us that he was concerned that his attic hatch was causing significant air leakage. We had the perfect product: the Hatchmaster Attic Stairway Cover. This lightweight, durable cover secures around the perimeter of the attic hatch frame. It’s made of double-bubble reflective insulation, has a 15 R-Value, and a heavy-duty zipper to open and close.
