Will a Vapour barrier stop condensation?
A vapour barrier (sometimes referred to as vapour retarder) is typically a plastic or foil sheet used for damp proofing to prevent interstitial condensation from forming in various building assemblies such as walls, roofs, foundations and floors.
How do you stop condensation on a corrugated roof?
Correct Insulation Installing a high-quality insulative material is the perfect way of preventing the internal face of your corrugated roof from getting too cold and reaching the dew point.

What causes condensation under metal roof?
Condensation forms when warm, moisture-laden air hits a cold surface. In the case of metal roofs, it happens when warm, moist air from inside the house is driven into, and trapped inside of, the cavity beneath the roof. When the metal roof’s temperature drops at night, the air condenses on the underside of the roof.
What is the best insulation to put under a metal roof?
Fiberglass Batts The higher the R-value, the more insulating the material is. Variable R-value is key because different climates need different levels of insulation.
