Roof anti-condensation membranes

One of the basic conditions for the good functioning of a modern roof is the use of the roof membrane with high permissiveness to vapours (anti-condensation) mounted under the main covering.

The anti-condensation membrane guarantees the drying of all roof layers when ventilation of the space underneath the main covering is provided.

It facilitates the passage of water vapours from inside the roof thermal insulation to the outside. Thus, the amount of vapours accumulated in the roof construction is limited and no condensation can be created in the roof, especially in the mineral wool layer.

In this way the structural elements of the roof, the thermal insulation, the interior finish of the building will not be affected by condensation water.

Wetterbest® also offers the special Dripstop self-adhesive membrane, which adheres to the inner metal surface of the roof panels during their automated profiling, replacing the use of the classic vapor-permeable membrane formulation.

The Dripstop membrane is an economical way to solve the condensation problem inside buildings without thermally insulated roofs, preventing water from leaking inside the building, extending the life of metallic coverings, increasing acoustic insulation and reducing rainfall noise.

Dripstop has a high water storage capacity that may result from the condensation phenomenon. The use of the Dripstop membrane eliminates the most common effect of condensation inside the buildings, namely dampness. Its performance is different depending on the material weight and the roof inclination.

The Dripstop membrane is resistant to acids from animal manure and bacteria, it can be washed with water.

Dripstop is used for non-insulated roofs and walls in industrial spaces (production halls, workshops, etc.), logistics (warehouses, warehouses, garages etc.), agro-zootechnical (cereal silos, zootechnical farms, etc.) buildings.


Qualities and benefits:

  • High and uniform permissiveness throughout the surface
  • Tensile strength, which facilitates assembly
  • Resistance to the harmful effect of moisture

Wetterbest®’s covering systems use Dachowa anti-condensation membranes with 115, 150, 165 or 185 gr/sqm densities.

Another advantage of this type of membrane is that it facilitates the assembly service – the installers will no longer have to mount the membrane over the roof structure (in most cases, the thermally insulated roofs do not have a continuous bed of boarding, which hinders access and increases the risk of falling from height);
