Novia Black+ FC125

Our 125gsm , 3-ply, Class W1 waterproof breather membrane for Timber Frame Floor Cassette Applications

Product Overview

Novia® Black+ FC125 is a high quality, strong and versatile floor cassette membrane for use in timber frame wall applications. Novia® Black+ FC125 is a 3-layer membrane with a microporous core. It has excellent Class W1 water resistance and is airtight, yet remaining vapour permeable with high breathability. Novia® Black+ FC125 reduces the risks of interstitial condensation around connections to wall panel detail. It is used to maintain airtightness at floor junctions, installed around the floor cassette and connected to the internal air and vapour control layer (AVCL). Novia® Black+ FC125 is completely black on one side, grey on the reverse, with no text or images, except for a 150mm overlap line.

Installation Tapes: Novia offers a range of installation tapes to join the cassette membrane to the vapour control layer above and below the floor junction. The use of tapes will result in the correct seal being formed as required for the AVCL to perform correctly. To connect Novia® Black+ FC125 to an internal AVCL we offer Novia® Double Sided Butyl Tape for use when connecting the floor cassette membrane to the AVCL and Novia® Breather Membrame Lap Tape (BMLT) for use along the overlap.
