Sleeves For Radon-Tight Pipe And Cable Sealing

The Partel KABSEAL GAS is a radon-resistant sealing grommet designed for the airtight sealing of pipes and cables in building envelopes, including floor slabs, walls, and ceilings. Suitable for both internal and external use, this durable grommet is made of permanently flexible rubber and offers exceptional adhesion, waterproofing properties, and resistance to ageing. 

It is essential in newly constructed buildings to prevent health-hazardous gases from infiltrating living spaces through floor slabs, walls, or ceilings. To impede the ingress of harmful gases such as the radioactive noble gas radon from the subsoil, appropriate barriers, including seals and sufficiently thick building material layers, must be established. To avoid the convective transport of radon due to air pressure differences, it is crucial to ensure airtight design for connections, joints, openings, and other building elements. 

KABSEAL GAS provides an effective radon-resistant solution for maintaining airtightness, ensuring long-lasting performance and durability in various construction projects. By following the installation guide and taking the necessary precautions, you can achieve optimum adhesion and a secure seal. Choose Partel KABSEAL GAS for a reliable and efficient sealing solution for your pipes and cables, protecting your building from harmful radon gas and ensuring a healthy living environment.
