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.
Wet attic condensation.
Condensation on your ceiling can cause water damage and promote the growth of mold or mildew.
In the event of the attic not being properly ventilated this would condense on the underside of the roof.
The colder the air is inside the duct the greater the chance of ductwork sweating.
It is common for poorly vented and insulated attics to develop attic condensation.
Condensation will arise as a result of warm moist air penetrating up through the ceiling.
As the humidity level rises outdoors condensation will gradually begin to form on the surface of your air conditioning ducts.
Moisture forming on the glass window panes or other flat surfaces.
It can also cause mold to grow on roof sheathing trusses rafters and ceiling floor.
This condensation can form droplets of water and accumulate into the insulation below.
Drying out a wet attic placing a dehumidifier inside the attic will help to draw out moisture from the surrounding environment.
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.
Signs of condensation in the attic may include the following.
For each relative humidity rh value there is a temperature value below which the condensation will start.
Improper ventilation and insulation of home attic space can produce high humidity levels and trap.
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.
This accumulation can leak through the attic floor and into your living space.
A moist attic means moist insulation and moist insulation is less effective.
The best solution for controlling moisture is at its source.
However you ll need to drain it frequently in order for it to function properly.
Also because airflow is not uniform significant condensation may still occur.
Once the dehumidifier s storage tank is full it won t be able to remove any more moisture.
