Assemblage rules:
The foil under the roof is installed in compliance with the standard DIN 4108 ensuring ventilation under the foil, fixed with battens and rafters, with upward inscription. Given that Bilka 180 g foil is permeable to the vapors of the composition, it can be mounted directly on the heat insulation, the ventilation channel between the foil and insulation will not occur. The foil is mounted parallel to the eaves, with an overlap marked on the roll edge with a colored stripe (min. 10 cm). It will be mounted given the direction of the water flow, it can cross over the ridge of the roof. The foil should be protected from direct exposure to UV radiation within one month of installation and from the effects of scattered radiation in max. three months, by the installation of insulation on the inside.
Storage and warehousing rules:
