BILKA ALU 90 Foil
Vapor barrier foil
BILKA ALU 90 Foil is a multilayer film consisting of one layer of metalized polypropylene film, polypropylene mesh, and polyethylene film. The BILKA ALU 90 Foil is designed to perform a vapor barrier in the construction of roofs. The metalized layer reflects thermal radiation, preventing heat loss. Product is an insulating barrier to water vapor and the wind. Such membranes can be used in all ventilated and non-ventilated roofs.
Technical characteristics:
- specific weight: 90g/m²± 10%;
- resistance to tearing: ≥100N
- temperature range: -30 : 70⁰C
- Sd 50m ± 30%

Assemblage rules:
BILKA ALU 90 Foil should be mounted on the “hot” side of the thermal isolation of the roof or walls, aluminum side in the direction of the room. The foil can be laid in parallel or perpendicular to the roof rafters. In the case of perpendicular installation to the rafters, the installation should start along the roof’s crest and the following foil bands to be mounted under the previous layer, using a 15 cm overlap and seal the connection with the special tape. In the case of parallel installation to the rafters, mount continuously under the rooftop, using a 20 cm overlap and if possible, connect the foil strips in the rafters area and also seal with special tape. The foil should be fixed with nails or staples every 10-15 cm. After assembly, secure all fixing points, connection and foil joints with a special tape in order to prevent the infiltration of water vapor from the room into the thermal isolation layer.
Storage and warehousing rules:
Protected from direct exposure to atmospheric conditions, away from heat sources (min 1 m).
