KAFLEX mono/duo – Cable Sealing Grommets
Penetrations are where air barriers and WRB systems are most at risk of failure. KAFLEX sealing grommets are purpose built to close those gaps, delivering an airtight and weathertight seal around cables and pipes in both facades and roof linings.
Made from high quality EPDM, the integrated adhesive flange bonds directly to membranes, underlays, rigid sheathings, and rigid air barriers. The pressure seal around the cable means pipes and cables can be pulled or pushed through without damaging the airtightness layer.
Key Features:
- Airtight and watertight for the life of the building
- High quality EPDM: flexible, elastic, and durable
- UV stable up to 180 days
- Integrated adhesive flange with release paper
KAFLEX multi – Cable Sealing Grommet
Where multiple cables pass through a single point, KAFLEX multi handles up to 16 individual penetrations in one grommet (Ø 4.8–12 mm each). Made from high quality, flexible EPDM, it’s compatible with membranes, underlays, rigid sheathings, and rigid air barriers. The product comes as an EPDM patch without integrated adhesive, giving you flexibility in how it’s applied.
Key Features:
- Seals up to 16 cable penetrations in a single grommet
- Airtight and watertight for the life of the building
- UV stable up to 180 days
- Long term durability
KAFLEX post — Retrofit Sealing for Installed Cables
Designed for cables and conduits already in place (up to 20 mm diameter), KAFLEX post provides a quick, permanently airtight seal without removing or repositioning the cable. Diffusion open and compliant with DIN 4108, SIA 180, and OENORM B8110-2, the problem solver of the range.
Key Features:
- Designed for already installed cables up to 20 mm
- Airtight for the life of the building
- Extremely flexible and elastic
KAFLEX is a CodeMark approved component of the Equitone system. If you’re installing Equitone fibre cement cladding, this is how you seal every penetration properly and why Progressive Materials stocks it.
