Novia Class B-s1,d0 500 Gauge FR Virgin Polythene

Installation Tips

All laps and edges should be fully sealed and taped. For air & vapour control layer installations, we recommend using a minimum 30mm width Novia® Double Sided Butyl Tape for all overlaps and around framework. To ensure a fully airtight seal, use a single sided tape, such a Novia® Aluminium Foil Tape or Novia® Metallised BOPP Tape to keep the overlap securely in place. Any mechanical fixings, must penetrate through the butyl tape to seal around any puncture created by the fixings. Where additional sealing is required, for example internal corners, floor sections or window reveals, the use of Novia® AirSeal 310 FR should be considered.
