Pole Barn Roof Sweating

Warm air has the ability to hold more moisture than cold air.

Pole barn roof sweating.

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. In a building such as a pole barn condensation can damage building materials. 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.

Condensation occurs when warm moist air contacts cold surfaces. Vapor barriers can help to keep condensation under control if installed in right places. Having vents in all elevations of the shed is an effective way of minimising metal roof sweating. In order to control condensation in your pole barn you need insulation a vapor barrier and adequate ventilation.

We ll add a vapor barrier so the moist air does not flow up through the insulation and condense on the roof. This is an easy affordable diy solution that can be d. Preventing condensation in a pole barn condensation forms when warm air comes into contact with a cold surface. 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. The amount of condensation depends on temperature differences and dew point.
