DAFA HiFoil vapor barrier

DAFA HiFoil is an intelligent moisture-adaptive vapor barrier that adapts to the humidity conditions.

DAFA HiFoil moisture adaptive vapor barrier

HiFoil is used for construction with special moisture-adaptive vapor barrier requirements. DAFA HiFoil is an intelligent moisture-adaptive vapor barrier that adapts to humidity conditions. If moisture builds up on the outer side of the vapor barrier, DAFA HiFoil wicks the moisture to the inner side, where it is dissipated via the building’s ventilation system.

When renovating a roof, you can establish the DAFA HiFoil vapor barrier from above, avoiding having to change the ceilings.

DAFA HiFoil is used for applications such as:

Exterior roof renovation
Residential and multi-story buildings with roofing felt or an unventilated cavity above a roof
Roof elements/cassettes – modules

Material

The product consists of polyethylene (PE) material with a moisture-absorbing polypropylene (PP) fleece layer.

DAFA HiFoil vapor barrier is a declared product in the Supply Chain Declaration Portal for New Construction Generation 4
Allows the migration of condensation in the structure while still being close to normal vapor pressure
Easy to trim using a utility knife
It can be used in ceiling and wall structures
