DriStud REPEL Flexible Air Barrier

Fire Retardant, Vapour Permeable, Water Resistant, Flexible Air Barrier

Categories: , ,

DriStud REPEL is a fire retardant, water resistant, vapour permeable, flexible air barrier, featuring a green, quattro-laminate synthetic membrane consisting of two outer non-woven layers with scrim. Installed over wall framing, it provides a secondary weather-resistant layer which prevents the accumulation of moisture.

DriStud REPEL is a reinforced flexible wall underlay that is suitable for use as temporary weather protection to allow interior works to continue inside the building without the exterior wall cladding fully in place (for up to 90 days).
