• Light-duty air barrier and variable vapour retarder for internal applications
• Polyamide film adapts vapour diffusion resistance to ambient humidity
• It is semi-transparent for ease of installation
• It prevents mould, timber rot, corrosion, and loss of thermal resistance
• It is non-perforated and non-conductive to prevent air and electrical leaks
