In a building such as a pole barn condensation can damage building materials.
Pole barn roof sweating.
The five key points to stop your metal roof sweating are.
Preventing condensation in a pole barn condensation forms when warm air comes into contact with a cold surface.
The key to getting condensation to evaporate is air flow.
Vapor barriers can help to keep condensation under control if installed in right places.
When this warmer air contacts cold surfaces in your pole barn condensation forms since the air loses its ability to retain as much moisture.
Traditionally we ve insulated the roof panel to try and keep the temperature on the panel from reaching the dew point.
But a preinstalled membrane may be even more effective at removing condensation.
This is an easy affordable diy solution that can be d.
Condensation occurs when warm moist air contacts cold surfaces.
Ceiling level vapor barriers are a bad idea because they keep water vapor trapped inside the building rather than allowing it to exhaust through a continuous ridge vent.
We ll add a vapor barrier so the moist air does not flow up through the insulation and condense on the roof.
Warm air has the ability to hold more moisture than cold air.
Having ventilation holes around the roof at eaves level and in the gable walls allows moisture rich air to escape.
The amount of condensation depends on temperature differences and dew point.
