For a ventilated facade, selecting the appropriate windproof membrane is essential to guaranteeing the durability and effectiveness of the building’s exterior. By serving as a shield against environmental factors like wind and moisture, a windproof membrane improves the functionality of the facade system.
Choosing a windproof membrane involves taking a few things into consideration. First, think about the building’s location and climate. Selecting a membrane that is appropriate for your particular environmental conditions is crucial because different membranes provide differing degrees of protection against wind-driven rain and humidity.
The membrane’s composition is yet another important factor. Advanced synthetic blends, polyester, and breathable polypropylene are common materials. Breathability is important because it lets moisture vapor escape the facade, preventing condensation and preserving the building’s structural integrity over time.
Evaluations should also be conducted regarding the facade system’s compatibility and installation technique. Certain membranes are made to be easily installed and work with various kinds of facade cladding materials, guaranteeing a smooth integration and best possible performance.
In addition, the membrane’s resilience to UV rays and longevity are crucial components. Long-term exposure to sunlight won’t cause a durable membrane with UV resistance to deteriorate, extending the facade system’s lifespan and lowering maintenance costs.
Finally, take into account the standards and certifications the membrane satisfies. Seek membranes that meet the necessary building codes and standards for waterproofing and wind resistance. This guarantees that the facade system satisfies legal requirements and operates dependably in a range of environmental circumstances.

The concept of a windproof membrane
For a ventilated facade, it makes sense to begin with the definition of this windproof membrane.
The term for unique building textiles is this. It is an insulating material with multiple layers, at least two of which are present. Polypropylene is the basis for their manufacture.
The spanbond, the outer layer that is woven, is strong and resistant to ultraviolet light. He adjusts the thickness, color, and texture of the film. A microporous membrane is present inside. She can pass steam, but she can also hold onto moisture.
There is no release of toxic or dangerous materials when the film heats up.
Membranes’ primary functions include keeping the interior of the building comfortable and shielding the walls from harmful elements like fungus and mold.
Selecting the appropriate windproof membrane for a ventilated facade is essential to guarantee longevity and energy economy in your house. There are many options available, ranging from strong synthetic membranes to breathable films, so the choice depends on the desired performance, budget, and climate. While synthetic membranes offer better wind resistance, breathable membranes stop moisture from building up inside the walls. You can choose wisely and extend the lifespan and effectiveness of your ventilated facade system by being aware of these variations and assessing your unique requirements.
Application area
As you are already aware, the membrane’s primary purpose is to shield the ventilated facade’s thermal insulation layer from wind and moisture. Concurrently, the building’s overall technical specifications rise, as does the weight on the foundation and pr.
In actuality, wind protection is necessary to guard against the following:
- water;
- atmospheric effects;
- increased humidity;
- thermal losses;
- mechanical damage.
There is unilateral permeability in the membrane. As a result, the material retains moisture and keeps it from penetrating and harming the facade. She also cleans the actual premises of steam.
In actuality, the material gives homes comfort and dryness.
Therefore, if we are discussing the ventilated facade, you cannot refuse to use these films in any circumstance. Everything will start to fall apart and decay rapidly without it.
The question of combustibility
How safe it is to fuel this membrane is a question that many have.
Certain non-combustible materials are used in their production. When exposed to flame, the material will burn down to its base and then extinguish itself.
There is no fire hazard with the coating. On the other hand, an open fire has the potential to spread across the surface.
The combustibility group is taken into consideration when choosing the material, along with the application conditions.
Only non-combustible films with NG labeling and safety category KM-0 may be used for ventilation facades.
It’s the kind of movie that possesses all the required qualities.
Varieties
It is worthwhile to thoroughly examine the selection before purchasing a specific membrane. I’m not sure if the prices are significantly different. Nevertheless, every kind of material has unique qualities.
- Permamine and polyethylene . The cheapest option. But the operational period is very low. Relevant only as a temporary protection of the facade;
- Windbreaker slabs . For their production, coniferous wood is used. The upper layer is processed using paraffin. Good decision against strong lateral wind;
- Non -woven diffuse films . They are made on the basis of polymers. Differ in rough coating, which does not allow condensate to accumulate on the surface. Well opposes wind loads, temperature differences and frosts. Knows how to remove moisture from buildings;
- SuperDiffusion film . It differs in multi -layer. It is made on the basis of polymer fibers. Has water -repellent and windproof properties, protects well from vaporization. If you follow the installation rules, the service life will be more than 25 years;
- Universal membrane . Here are all the advantages that previous films have. Widely used in the construction of high -rise buildings and private houses. A great choice for roofing, frame ceiling and ventilation facade. Stable ultraviolet. It copes with increased wind loads. Service life is about 50 years.
I believe it is no longer difficult to choose between the available options.
In all honesty, the final two choices on the list emphasize the importance of improved wind protection. Diffusion coatings are also applied more precisely in multi-story buildings.
What to pay attention to
Whether or whether the movie is going to be black or some other color doesn’t really matter.
Selecting the appropriate protective membrane is crucial when organizing the building of a ventilated facade for the purpose of lining the house with different materials.
It needs to fulfill the following specifications:
- Stability to fire and a class of combustibility. It is allowed to use exclusively non -combustible type of membranes. Therefore, pay attention to the labeling of NG. The fire safety class should be KM-0;
- The material should not let air through itself with a strong wind, while taking the steam out. This is determined by air and moisture permeability. The vapor permeability should be 0.1 unit, and the breathability of 1,500 units. The characteristics are determined in m2*h*pa/mg;
- Water permeability. In the case of the ventilated facade, the degree of water permeability should be small;
- Resistance to mechanical loads and gap strength. This largely determines how many points of fixing the film will have to be used;
- Elasticity. The material must be stretched to maintain its structure and integrity in stretching;
- Life time. Focus on films that can perform their functions for at least 40-50 years.
Such material can be purchased as rolls. They are 50 meters long and 120 centimeters wide.

For a ventilated facade, selecting the appropriate windproof membrane is essential to guaranteeing the longevity and functionality of your structure. In addition to providing protection from wind-driven rain, the membrane lets out moisture vapor, which keeps mold and structural damage at bay.
Think about things like breathability, longevity, and facade system compatibility when choosing a windproof membrane. Superior membranes, such as those made of polypropylene or polyethylene, are frequently chosen because of their superior resistance to weather and UV rays.
Evaluating the membrane’s water resistance rating, which is commonly expressed in millimeters of water column pressure, is also crucial. Select membranes with a higher rating to guarantee better protection from severe rain and bad weather.
It’s also important to consider installation ease and compatibility with insulation materials. Certain membranes have integrated tapes or adhesives that make installation easier and save labor costs and mistakes.
Finally, to find the best membrane for your unique project requirements, speak with facade engineers or manufacturers. They can offer insightful information about how well a product works, maintenance requirements, and building code compliance.
