Vapor barrier films ML AL are specially designed to provide high resistance to vapor diffusion. Their unique structure and characteristics make them an ideal solution for various construction applications where maximum impermeability is required.
Greater resistance to diffusion of vapour-insulating films ML AL
A special feature of this type of film is its greater resistance to diffusion compared to other vapor barriers. This is achieved by spraying aluminum onto one of the film layers, which drastically reduces vapor permeability.
Description of vapor barrier film ML AL
Very low vapor permeability is achieved by spraying aluminum onto one of the film layers. This is crucial in all applications where maximum impermeability of the building envelope must be achieved.
Application in inaccessible spaces
This applies to all roofs and walls that cannot be ventilated for various reasons. This sometimes occurs with repaired roofs and walls whose coatings and elevations cannot be ventilated.
Reflective surface
It is precisely the sprayed aluminum that gives this vapor barrier a mirror-like appearance that reflects sunlight. The reflective surface plays an important role in controlling the temperature inside the building.
Impact on heating
This is of great importance in rooms heated by devices that emit thermal radiation. The heat spreads through the room like radiation and can be reflected off the mirror surface, contributing to more efficient heating.
Energy savings
The application of this vapor barrier film under gypsum boards can save energy, as its reflective surface reflects the radiation that reaches underneath the gypsum boards. This feature can significantly reduce heating costs.
Standards and certification
Vapor barrier films ML AL meet the requirements of the European standard EN 13984 and are marked with the CE symbol. This guarantees high quality and compliance with international standards.
Installation advantages
Easy installation and long service life make this film a popular choice among construction professionals. Its ability to effectively prevent vapor penetration contributes to a healthier and more stable indoor environment.
Vapor barrier films ML AL represent an advanced solution for vapor control in construction objects. Their high resistance to diffusion, reflective surface, and compliance with European standards make them an ideal choice for various applications.
