Product benefits

In many areas, for example airports, hospitals, shipping and rail transport, building materials need to meet heightened demands for fire protection and sustainable construction. Where toxic gases and smoke present special hazards, or structures need to meet Green Building standards, halogen-free materials should be used for pipe insulation.

With Kaiflex RT-HFplus s2, Kaimann has a pipe support that is the ideal complement to the Kaiflex HFplus s2 halogen-free insulation system. It is designed for interior use in HVAC and cold water applications in industry, food production and shipping. Combined with Kaiflex HFplus s2 tubes, this pipe support demonstrates Euroclass DL-s2, d0 and thus limited smoke development. The result is a well-designed insulation system solution that is free of PVC, chlorides and brominated flame retardants, and so fully meets the declaration criteria for low-pollution building materials. 

Halogen-free insulation against cold bridges

Designed to fit the dimensions of Kaiflex HFplus s2 tubes and sheets, Kaiflex RT-HF provides full insulation coverage to prevent cold bridges and thus energy conservation. The thermal decoupling of steel, copper / stainless-steel pipes from the clamps of the pipe support prevents the formation of condensation and thus pipe corrosion. This makes product changes, and pipe mountings as weak points in pipework insulation, things of the past.

Easy installation

Consisting of two highly compression-resistant, load-bearing PIR foam bearing segments embedded in a closed-cell rubber insulation and covered with a thin, stabilising aluminium sheet, Kaiflex RT-HFplus s2 is easy to install. The connections are closed with a tongue-and-groove closure. A tape overlap seals off the seam from the outside, providing full coverage. This provides safety and very high sealing against water vapour diffusion.

The Environmental Product Declaration (EPD) makes the ecological assessment of the insulation materials even more transparent, assisting in the planning and certification of sustainable buildings.
