You’re not the only one who gets all clammy when the humidity is high. And while you might be able to stay dry by doubling up on the antiperspirant and donning your most breathable shirt, dealing with your home’s “sweaty ductwork” is a little more complicated.

But can my attic have sweaty ductworks?

That’s right. Consider this: Water is everywhere, and the air can only hold so much. When relative humidity reaches 100%, the air is holding all the water that it possibly can, and water vapor will begin to drop out of the air and condense into a liquid.

When warm, humid air meets the colder surface of your home’s HVAC ductwork, it condenses much like the outside of your icy pitcher of lemonade on a sultry Louisiana day. Since hot air can hold more moisture than cold air, you might think that the high temperatures in your attic will prevent duct sweating. Wrong. When attic temperatures drop at night, so does the surface temperature, making condensation inevitable there as well.

Why sweaty attic ductwork is a reason to sweat

  • Moisture can drip off the ducts onto insulation, and depending upon what type you have, compress it and reduce its R-value and effectiveness.
  • It can cause ugly ceiling leaks that get even uglier when they lead to ceiling collapse or drywall rot.
  • It can supply mold with the water it needs to thrive.

Avoiding the dreaded sweaty ductwork

So what can you do to prevent the dreaded sweaty attic duct issue, even in a place with as much humidity as Southern Louisiana?

  • Have a professional install proper and adequate insulation, like spray foam insulation, around your attic ductwork. Condensation simply won’t form if you can prevent the meeting of warm, moist air and cold ducts.
  • Have a professional check to see that your attic has proper ventilation to release natural moisture in the air.

Open cell spray foam to the rescue

Attic encapsulation with open cell spray foam insulation not only offers unsurpassed insulation, but also seals gaps through which high temperatures may otherwise force hot air. Even better, open cell spray foam’s spongy consistency allows moisture to pass through it rather than get get trapped. Even if your attic develops a leak, the water will pass through the spf insulation and alert you to a problem, rather than sitting beneath your roof inviting mold and/or rot.
