One of the basic requirements of a good functioning of a modern roof is the usage of roof membranes with high affordability vapor (anti-condensation) installed under the main casing.
Anit-condensation membrane guarantees the drying of all layers of the roof, when the ventilation of the space under the main casing is insured.
It also facilitates the passage of water vapor from the roof insulation to the external environment. Thus, the quantity of vapors that gathers in the roof construction is limited and it can no longer appear condensation in the roof, especially in the mineral wool.
In this way the structural elements of the roof, insulation, interior finishes of the building will not be affected by water from condensation.
Qualities and advantages:
Wetterbest® also offers you the special autoadhesive membrane Dripstop, which it is sticked to the inner metal surface of the corugatted sheet, durring the automatic profiling, replacing the utilization of the clasic formula of vapor-permeable mebrane.
The Dripstop membrane represents an economic way to solvethe problem of condensation inside the buildings without thermal-insulated roof, preventing the dripping of the water inside the building, extending the lifespan of the metal roofing, increasing insulation and reducing acoustic noise produced by the rain.
Dripstop has a great capacity of storing the water, which may result from condensation. By using the Dripstop membrane, it is eliminated the occurrence of the most common effect of condensation, namely, dampness. Its performance is different depending on the gram weight of the material and on the slope of the roof.
Dripstop membrane is resistant to acids and bacteria from animal manure and it can also be washed with running water.
Dripstop is used at roofs without thermal insulation and at the walls of industrial buildings (production halls, workshops, etc.), logistics buildings (warehouses, shops, garages, etc.), animal breeding and agriculture buildings (grain silos, livestock farms, etc.)
Another advantage of this type of membrane is that it facilitates the assembly – installers no longer need to install membrane over the bone structures of the roof (in most cases, roofs insulated thermally do not have bed continuous sheathing, which complicates access and increases the risk of falling);
