Remains tight in winter when humidity in the cavity is low to prevent moisture from entering.
Increases permeability in summer to let moisture escape, helping to keep the wall dry.
Continuous indoor air barrier creates a better performing building envelope.
Dynamic performance and permeance rating compared to traditional kraft insulation or polyethylene sheeting.
Senses and adapts permeance to varying humidity throughout the year to keep the cavity dry.
When installed with standard tape and sealing practices, creates an air barrier that has been tested under stringent performance guidelines.
