Breathe Easy, Learn Better: How Aeroseal Helps Schools Boost Student Performance

Let’s face it—no one’s ever aced a math test while distracted by stuffy air or a classroom that feels more like a sauna. But here’s a secret that’s hiding in plain sight: the quality of the air in your school is quietly shaping how well students learn, focus, and even show up for class.

Why Air Quality Is the Unsung Hero of Student Success

Sure, schools pour effort into curriculum and tech, but if the air’s not up to scratch, everyone’s working uphill. Research shows that poor ventilation leads to higher levels of carbon dioxide (CO₂) and other nasties—think dust, mold, and whatever’s lurking in the crawlspace. And when CO₂ goes up, test scores and attention spans go down.

• A major review found that dropping CO₂ from 2,100 ppm to 900 ppm made students 12% faster at tasks and 2% more accurate.
• Reducing CO₂ from 2,400 ppm to 900 ppm bumped up national test scores by about 5%.
• Better air even means better attendance—cutting CO₂ from 4,200 ppm to 1,000 ppm led to a 2.5% increase in daily attendance.

What’s Polluting the Classroom Air?

Often, the culprit is hiding in the ductwork. Leaky, outdated ducts suck in air from all the wrong places—attics, mechanical rooms, or even outdoors near car parks. This means:

• Contaminants bypass filters and head straight for the classroom
• HVAC systems can’t keep up, so the air gets stale
• Temperature and humidity bounce around, making it tough to focus

And this isn’t just an “old building” problem—newer schools can have the same issues if their ducts aren’t tested and sealed.

Comfort Counts—And So Does Ductwork

It’s not just about air quality. Even a few degrees’ difference in classroom temperature can make or break a student’s ability to focus. Cooler rooms with steady humidity help brains work better—and keep complaints to a minimum.
