Dripstop Condensation Membrane
Dripstop membrane on the reverse of the sheeting provides a medium for trapping moisture in the specially designed pockets formed in the felt 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.
Dripstop is a special membrane that solves condensation problems inside buildings with uninsulated roofing. When the condensation process starts, water drops start to form on the underside of the roof. Dripstop absorbs around 1.000 g/m2 of water which is stored in tiny pockets in the membrane. When it becomes warmer, water starts to evaporate back into the air and the Dripstop membrane will start to dry off again.
Dripstop is self-adhesive and is applied to the reverse of the sheet in the roll forming process. This means that when your sheets arrive they’ll have Dripstop already applied and they’ll be ready to use without any tricky installation of the membrane.
DripStop can be used in virtually any environment or structure where condensation is a problem. However the structure must have a guaranteed supply of airflow such as open sided or fronted buildings, for instance agricultural barns or industrial units. Remember, DripStop does not prevent condensation; the structure must be adequately ventilated to allow the material to dry out between the cycles in order for the membrane to work properly. If condensation is a problem then we do have vented sheets which could help alleviate the problem.
If you’re interested in having the Dripstop membrane applied to your sheeting then you can select from a wide range of sheet colour, thickness and finish.
