Wet Attic Condensation

It can also cause mold to grow on roof sheathing trusses rafters and ceiling floor.

Wet attic condensation.

A moist attic means moist insulation and moist insulation is less effective. Improper ventilation and insulation of home attic space can produce high humidity levels and trap. The colder the air is inside the duct the greater the chance of ductwork sweating. 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.

However you ll need to drain it frequently in order for it to function properly. If you set the air conditioning temperature higher then the temperature of the return air will also be higher and there will be less chance of sweating at the ahu. First water dripping off of your ducts and onto your insulation can cause the insulation to compress which decreases it s r value or ability to insulate. This accumulation can leak through the attic floor and into your living space.

As the humidity level rises outdoors condensation will gradually begin to form on the surface of your air conditioning ducts. In the event of the attic not being properly ventilated this would condense on the underside of the roof. Once the dehumidifier s storage tank is full it won t be able to remove any more moisture. Moisture forming on the glass window panes or other flat surfaces.

The best solution for controlling moisture is at its source. Signs of condensation in the attic may include the following. To prevent frost condensation from developing in your attic you must eliminate or reduce the amount of air leakage into the attic as well as improve insulation ventilation to allow moist air to escape the roof. When water condenses and drips into your attic or home it can cause a some serious secondary problems.

It is common for poorly vented and insulated attics to develop attic condensation. Traces where water has trickled down the walls. Condensation on your ceiling can cause water damage and promote the growth of mold or mildew. Drying out a wet attic placing a dehumidifier inside the attic will help to draw out moisture from the surrounding environment.

For each relative humidity rh value there is a temperature value below which the condensation will start.
