Is it normal to have condensation on top of vapor barrier?

To avoid condensation on the vapor barrier itself, you want to avoid a large temperature differential from one side to the other.

How do you stop condensation on basement walls?

Insulate Your Basement: Insulating the places where condensation builds up can also help to eliminate moisture. Covering those places, such as walls, pipes, and ducts, with insulation, will help keep warm air from coming in contact with the cool surfaces, thus preventing condensation.

What is the difference between a vapor barrier and a moisture barrier?

Air Barriers Provide Superior Moisture Protection for a Home Over Vapor Barriers. Air barriers are designed to prevent the flow of air, and the moisture attached to it, from entering a building envelope. A vapor barrier only aims to prevent the transport of moisture by vapor diffusion into a home’s building envelope.

Do you need a vapor barrier with rigid foam insulation?

Foam insulation usually does not require a vapor barrier. For some foam insulation types, such as closed-cell spray foam and foam board insulation, the insulation itself stops the movement of most water vapor.

Can you spray foam over vapor barrier?
