A Vapor barrier must be installed professionally if there is to be no moisture damage. The reason for this is that a construction with a Vapor barrier can only be sealed with aluminum foil with some difficulty. However, in most cases, the fault lies with the workmanship rather than the foil.
It is often the connections that are troublesome when the aluminum foil is not applied correctly. It is possible, however, that the film can also be damaged when the sockets are attached. If you want to erect a vapor barrier in the attic, sauna, pool area, steam bath or cold store, be careful with the aluminum foil.
If the thermal insulation is still damp during installation, this must also be checked in advance. Thermal insulation in this case should not be allowed to dry completely until it is completely dry. Unless the aluminum foil is used, the water from the components won't be able to evaporate. Because of the sorption capacity of the material, air-dried components also contain several liters of water per square meter. Whenever aluminum foil is used as a vapor barrier, it should always be consulted by an expert. With everything properly laid out, aluminum foil provides a high-quality barrier.
The films can be customized to suit any structure and are available in different sizes and lengths. Especially suitable are multilayer metallization films. They reflect heat energy and add an extra layer of insulation.
