DR!PSTOP is a special membrane that solves condensation problem inside buildings with an uninsulated roof. When the condensation process starts, water drops start to form on the underside of the roof.
DR!PSTOP absorbs around 1.000 g/m2 of water which is stored in tiny places in the membrane. When it becomes warmer, water starts to evaporate back to air and DR!PSTOP membrane gets dry again.
DR!PSTOP 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.
