How Your Attic Impacts Your Home’s Air Quality

Few people associate their home’s air quality with their attic.  However, they should.  That’s because insulation works 24/7 to regulate a home’s temperature.  In fact, your home’s insulation should be thought of as a giant filter that is a major player in a home’s overall air quality.  Here’s what you need to know.

Critters Living in Your Attic Can Make You Sick

Many times, pests such as squirrels, insects, raccoons, bats, and mice can make their way into your attic through a home’s soffits.  While this is always a comprise to a home’s air quality, it’s even more problematic when the stack effect is present.  In the winter months, the stack effect will draw air from your attic to your basement. The opposite is true in the summer.  This additional air circulation promotes the inhalation of harmful chemicals that are found in animal fecal matter.  Particularly concerning is bat guano.  When the guano dries, it converts to a powdery substance.  If inhaled, it can lead to lung infections and even death.

Vermiculite Insulation

Vermiculite insulation can be recognized by its shimmering flakes.  At high temperatures, the flakes will expand. While not all vermiculite insulation is dangerous, a mine in Libby, Montana where much of the country’s vermiculite insulation came from, also contained deposits of asbestos.  When vermiculite insulation that contains asbestos is disturbed, the fibers within it become airborne.  When inhaled, the fibers can lead to cause lung cancer and mesothelioma.

Attic Moisture Issues

Mold growth in your attic is often the result of a leaky roof or ice dams.  When insulation becomes wet, it is no longer able to keep a home cool in the summer and warm in the winter.  Even more alarming is that mold can have a negative impact on a home’s air quality.  That’s because mold spores can float throughout your home.  When they are inhaled, they can cause respiratory infections, watery eyes, allergic reactions, and compromised immune systems.

"The Lindus people were efficient and quick taking out the old insulation and adding new spray foam and blow-in. All was done within the estimated time frame and the residuals were cleaned up.  A good job was done."

"Eric is great. We used him on my mom’s house for several projects: new doors, windows, re-insulating the inside of the roof in upstairs bedrooms, tearing down & rebuilding the garage. My sister also used Eric to install LeafGuard® on her own house, build her a new deck, and install a metal roof. We recently had a meeting to discuss building a new deck for me, to replace the old one. We will be using no-maintenance materials, so no more sanding, staining, painting."

"Jason and the insulating crew did a great job. I told Jason it looked like nothing was done when he finished cleaning, which is a very good thing.  The insulating crew did have a difficult time working under the bay window. They usually hold their spray gun about 2 ft. away from the surface. In our location, they only had a foot at the most. So, there was a lot of blowback, clean-up, and additional layers to get the final result."
