ACTIVE VAPOUR BARRIER
Intended for protection against moisture on sloping roofs. Thanks to the absorption layer, it delays the process of condensation while maintaining full protection of the roof’s thermal insulation. Mineral wool can be laid directly on Budfol Antydrop without additional reinforcement, which significantly reduces labor costs during roof insulation process.
THERMAL PROTECTION
The use of Budfol Antydrop in combination with a highly vapour permeable membrane guarantees full protection of the roof thermal layer.
ABSORPTION CAPACITY
Due to polipropylene non-woven layer, membrane has the ability to absorb moisture and thus delays the condensation.
PROTECTION AGAINST MOISTURE
Thanks to the use of polyethylene, which is characterized by low water vapour permeability, the film effectively protects the structure of walls and roofs from moisture.

MOUNTING & FASTENING
Subsequent strips of foil shall be mounted on the overlap, the size of which depends on the direction of laying – 15 cm for parallel laying and 20 cm for perpendicular laying to the rafters. The foil should be attached to the rafters with staples, and the overlapping strands should be tightly connected using double-sided Foliarex tape.
