Single bubble vapor barrier is designed to keep your metal roof from sweating. It is white on the bottom side and foil on the top side (against the metal). Where a felt paper or even synthetic felt paper attempts to trap moisture after condensation has occurred until it can evaporate, single bubble vapor barrier will prevent the metal from sweating to keep the inside of your building dry. It will also reduce the noise of rain on your metal roof and add a small insulating value as well.
In the morning when the sun comes up the steel on your roof is cool and the humidity is high – as the sun warms the steel on the roof naturally the outside of the roof heats up faster than the inside of the roof; this creates condensation and moisture has made it’s way into your building. Single bubble vapor barrier acts as a reflector and as the suns ray heat the steel the heat radiates through the metal to the tin foil side of the vapor barrier which in turn reflects back to the back side of the metal, eliminating the temperature difference that causes condensation which prevents the metal from sweating.
