Novia 4016 Breather Paper

This breather membrane meets the technical requirements of type 2 - BS 4016, the British Standard for breather materials. Breathers are designed for use in conjunction with vapour control laminates to protect insulation from draughts and build-up of dirt and moisture that can reduce its efficiency. They are positioned on the cold side of insulation, usually under cladding. They allow moisture vapour to pass through them but will resist the passage of liquid water.
