81 Frost-protected pipes Protective sheath made of polyethylene. Standard pipe made of PE100 RC. Self-limiting heating cable. Heat reflective aluminium. Closed cell polyethylene insulation foam. Smart and durable construction Polapipe® consist of a media pipe made of polyethylene (PE) approved for food use and a heating cable to prevent the water from freezing. Around the heating cable and a section of the polyethylene pipe there is also an aluminium foil that reflects and spreads the heat for efficient and economical heating. The PE pipe is insulated with high grade, flexible PE-based closed cell foam insulation. The lambda value of the insulation is 0.043 and since the cells are closed, the insulation maintains its high insulation value without the risk of water absorption. Outside the insulation is an outer sheath that is also made of durable PE, but with a lower density, which makes the sheath more flexible, allowing it to follow the terrain and ground conditions more easily.
