Wet Attic Condensation

Traces where water has trickled down the walls.

Wet attic condensation.

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. Drying out a wet attic placing a dehumidifier inside the attic will help to draw out moisture from the surrounding environment. When water condenses and drips into your attic or home it can cause a some serious secondary problems. The best solution for controlling moisture is at its source.

Condensation will arise as a result of warm moist air penetrating up through the ceiling. 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. It is common for poorly vented and insulated attics to develop attic condensation. Improper ventilation and insulation of home attic space can produce high humidity levels and trap.

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. A moist attic means moist insulation and moist insulation is less effective. Also because airflow is not uniform significant condensation may still occur. This accumulation can leak through the attic floor and into your living space.

Condensation on your ceiling can cause water damage and promote the growth of mold or mildew. This condensation can form droplets of water and accumulate into the insulation below. The colder the air is inside the duct the greater the chance of ductwork sweating. Moisture forming on the glass window panes or other flat surfaces.

Signs of condensation in the attic may include the following. It can also cause mold to grow on roof sheathing trusses rafters and ceiling floor. In the event of the attic not being properly ventilated this would condense on the underside of the roof. However you ll need to drain it frequently in order for it to function properly.

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