It is common in this context to refer to SD-values. During the course of an airtight component’s life, water migrates through the air layer layer equivalent to diffusion (Sd). When the thickness of an airtight component is 4 m, water vapour would take the same amount of time to pass through it as it would through a layer of air 4 m thick. As a rule of thumb, a vapour barrier is one that has a Sd value greater than 1,500 m. Within this range, all values are considered to be vapour retarders.
Varieties of foils can be used as vapour barriers to prevent moisture intrusion into thermal insulation. Glass fiber insulation may be laminated with aluminum foil, for example. Combinations of such insulations provide the best dampdichte folie. In the 1970s, aluminum foil was used to make vapour barriers.

What Is The Value Of Aluminum Foil As A Vapour Barrier?
Roofing Insulation With Aluminum Foil
Despite deteriorating faster than other materials, aluminum foil is still an effective material. A vapour barrier can be created at a reasonable price using aluminum foil. Aluminum foil should be glued over a large surface area if you plan on using it.
In pools, saunas, and other wet areas, aluminum foil is often used. Aluminum foil is also useful for insulating roofs. Vapour barriers are needed for this purpose. They prevent water from penetrating the roof.
The roof construction can be reached. The condensation water would create great damage upon condensing.
Vapour Barrier Made from Aluminum Foil
Vapour barriers should always be installed on the room side of thermal insulation. Otherwise, they will not work. In order to assure that the foil is processed correctly, many aluminium foils are labeled with the direction of the room inside. Aluminum foil is inexpensive and very durable, making it a great option for use in many applications.
Plastic and aluminium foil are commonly used as vapour barriers. They are often included with installations. Rolls of film typically measure 1.50 meters wide. A roll of aluminium foil measures between 50 and 100 meters long. Foil made of aluminum is tear-resistant, resists vapour diffusion, and resists tears. A laminated PE-aluminum vapour barrier can be useful in vapour-tight constructions. Adding a foil vapour barrier can increase thermal insulation. Foil can increase thermal insulation by 10%.
What Are The Ways In Which Vapour Control Layers Can Be Applied?
Moisture damage can be prevented by installing vapour barriers professionally. This is due to the fact that vapor barriers can only be used with aluminium foil as a sealing material. There is usually a problem with the workmanship rather than the foil.
When the aluminium foil is not applied properly, the problem is often with the connections. It is also possible for the film to be damaged when the sockets are attached. The timing for the installation of a vapour barrier is extremely important when it comes to attics, saunas, swimming pools, steam baths, and cold storage areas.
In addition to checking the insulation for dampness during installation, it should also be checked for corrosion. You should not allow the thermal insulation to dry if it is not completely dry. In contrast, aluminium foil prevents water from evaporating from elements. During the air-drying process, components contain a considerable amount of water per square meter due to the sorption capacity of the material. When using aluminium foil, always consult an expert before installing a vapour barrier. When everything is set up correctly, aluminium foil provides excellent performance.
