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.
Pole barn roof sweating.
We ll add a vapor barrier so the moist air does not flow up through the insulation and condense on the roof.
In order to control condensation in your pole barn you need insulation a vapor barrier and adequate ventilation.
Having vents in all elevations of the shed is an effective way of minimising metal roof sweating.
Condensation occurs when warm moist air contacts cold surfaces.
When this warmer air contacts cold surfaces in your pole barn condensation forms since the air loses its ability to retain as much moisture.
The key to getting condensation to evaporate is air flow.
Vapor barriers can help to keep condensation under control if installed in right places.
This is an easy affordable diy solution that can be d.
But a preinstalled membrane may be even more effective at removing condensation.
Preventing condensation in a pole barn condensation forms when warm air comes into contact with a cold surface.
In a building such as a pole barn condensation can damage building materials.
The five key points to stop your metal roof sweating are.
Having ventilation holes around the roof at eaves level and in the gable walls allows moisture rich air to escape.
Warm air has the ability to hold more moisture than cold air.
