The Phoenix Steels Anti-Condensation Membrane is a product designed to eliminate the problem of condensation. When the temperature and humidity conditions reach the dew point, the moisture condenses on the underside of the metal roof and forms droplets of water. This can often lead to damage of the contents of the building. This is a more cost effective way of stopping this problem rather than insulating the roof with such products as composite panel.
Anti-condensation backing is available on all Box Profile, 3″ Corrugated and Tile Form sheeting.
Condensation occurs when the temperature and humidity conditions reach the dew point and moisture occurs on the underside of the metal causing an internal drip.
The most common use for the moisture barrier is to protect whats inside the building and prevent any damage from drips.
For example, building you may used Phoenix’s Steels moisture barrier on are:

How It Works
The roof panel with the moisture barrier applied provides a medium for trapping the moisture in the specially designed pockets formed in the membrane. The moisture barrier holds the moisture until the conditions go back below the dew point and it is then released back into the air in the form of normal humidity.
The moisture barrier is self adhesive and is applied to the metal panel in the roll forming process. As a result the moisture barrier arrives at the site already in place and ready to be installed. The membrane is resistant to ageing, and has a rubber based adhesive that actually provides an additional layer of protection for your metal panel.
The moisture barrier is made up of a large number of interlaced PES fibres among which there is enough space to store water drops. The moisture barrier serves as a medium for absorbing condensed water drops which evaporate back into the air when the temperature rises. For this process it is important that there is some air circulation (ventilation) present.
