Attic Ductwork Condensation

When ductwork is touching it forms a very cold spot where they are touching thus condensation begins.

Attic ductwork condensation. The 1 746 square foot house has r 19 insulation between the rafters and between r 15 and r 20 of rigid foam above the roof sheathing. Ductwork located in an attic must be hung properly so that the insulation can do its job. It s a natural process and similar to the way a chilled soda begins to sweat once you take it out of the refrigerator on a hot day. The colder the air is inside the duct the greater the chance of ductwork sweating.

For more information on this. Condensation on air ducts can be a serious problem. Let s say your ductwork is in your attic. You can install insulation on the attic side of the register boot and you can make sure that your duct is adequately.

Condensation will begin to drip onto your attic insulation making it less effective at regulating temperatures inside your home. There are two main ways to solve this problem. As the humidity level rises outdoors condensation will gradually begin to form on the surface of your air conditioning ducts. So if you see unusual water staining on any of the ceilings in your home and the roofer has eliminated roof leaks it is likely coming from some fault with the duct system in your home.

Dripping condensation may also lead to a ceiling leak which not only looks bad but also rots drywall and can cause your ceiling to collapse over time. You can convert your vented unconditioned attic into an unvented conditioned attic. Over time condensation dripping from your ductwork onto attic insulation can cause it to compress which lowers its r value. Even though the air conditioning equipment appears to be operating normally humidity inside the house is between 60 and 65 and return ducts located in the attic show significant condensation.
