Novia Black+ FC125 is a premium, 125gsm high-performance breather membrane specifically engineered as a floor cassette membrane for use in timber frame wall applications. Designed with a sophisticated 3-layer membrane with a microporous core, it offers a specialised solution for protecting structures during the build phase and ensuring long-term thermal efficiency.
Novia Black+ FC125 delivers superior Class W1 water resistance and airtightness without compromising breathability. Engineered to minimise interstitial condensation at wall panel junctions, this high-performance membrane wraps floor cassettes to provide a seamless, airtight connection to the internal AVCL.
As a strong and durable breathable membrane, the FC125 is completely black on one side with no printed logos (except for a 150mm overlap line).
Key Features
- Advanced 3-Layer Construction: The FC125 is a 3-layer membrane featuring a high-tech microporous core that provides excellent Class W1 water resistance while maintaining high breathability.
- Optimised for Floor Cassettes: Specifically designed as a floor cassette membrane, it helps maintain airtightness at floor junctions a critical area for reducing heat loss.
- Superior Protection: Rated as a Class W1 breather membrane, it ensures the building remains waterproof against driving rain while remaining vapour permeable to allow interstitial moisture to escape.
- Airtight yet Breathable: The material is engineered for high water resistance and is airtight, yet it functions with high breathability to prevent condensation buildup within the insulation.
Installation -
To ensure a fully compliant, airtight seal, Novia provides a dedicated range of installation tapes for joining the cassette membrane to the vapour control layers (AVCL) above and below the floor junction. For a secure connection between Novia Black+ FC125 and the internal AVCL, use Novia Double Sided Butyl Tape. To seal the membrane overlaps, manyfacturer recommends Novia Breather Membrane Lap Tape (BMLT) to maintain the system's high-performance integrity.
