DR!PSTOP is made of a large number of interlaced PES fibres among which there is enough space to store water droplets. DR!PSTOP serves as a medium for absorbing condensed water droplets which evaporate back into the air when the temperature rises. For this process it is important, that there is some air circulation (ventilation) present.
When the outside temperature falls below the temperature inside a room, clad with single skin metal panels the non-insulated metal roof panels become colder than the inside room temperature. When warm air inside the room gets in contact with the cold roof panel, it suddenly cools down which immediately increases the relative humidity of the air. When it reaches the dew point, condensation occurs.
Tinman Steels Ltd are proud to offer DR!PSTOP anti-condensation backing felt as an addition product on our 32/1000R Box Profile, 34/1000R Box Profile, TILE1000 and PAN TILE Tile effect roofing sheets.
DRIPSTOP anti-condensation felt is self adhesive, and is applied to the metal panel in the roll forming process. As a result, DRIP STOP arrives at the building site already in place and set to be installed with the roofing panels immediately. The membrane is resistant to aging, and also provides an additional layer of protection for your metal roof.
The roof panel with DRIPSTOP anti-condensation felt provides a medium for trapping this moisture in the specially designed pockets formed in the membrane. DRIPSTOP holds that moisture until conditions go back below the dew point and it is released back into the air in the form of normal humidity.
