5. Functioning and principle of Lebit Lebit is thermo-elastic that is a liquid when cast and hard and elastic when cooled. Lebit is thermo-elastic that is a liquid when cast and hard and elastic when cooled. When used in heating pipes, the product creates a flexible section where it is applied, while the hard sections remain in place just a few centimetres further. When used in heating pipes, the product creates a flexible section where it is applied, while the hard sections remain in place just a few centimetres further. This hard and flexible combination can be repeated indefinitely in the pipes. The properties of Lebit never change. This hard and flexible combination can be repeated indefinitely in the pipes. The properties of Lebit never change. Heated pipes can contract or expand without any pressure as the pipe 'swims' in local fluid Lebit. Heated pipes can contract or expand without any pressure as the pipe 'swims' in local fluid Lebit.

6. Advantages of Lebit Seamless insulation (no cold bridging) Seamless insulation (no cold bridging) Resistant against groundwater Resistant against groundwater Completely water impermeable and thus resistant to corrosion Completely water impermeable and thus resistant to corrosion High heat insulation High heat insulation Electric isolation Electric isolation Flexible and slidable at the bearing point Flexible and slidable at the bearing point Internally flexible; stable external shape Internally flexible; stable external shape Can be processed during renovations under working conditions Can be processed during renovations under working conditions No sleeve connections, no support points (cold bridging) No sleeve connections, no support points (cold bridging) Also suitable for temperatures up to 200°C Also suitable for temperatures up to 200°C 100% recyclable 100% recyclable Lebit is made from completely natural materials Lebit is made from completely natural materials

8. Processing properties of Lebit Lebit combines the various properties of the raw materials to create a unique product Lebit combines the various properties of the raw materials to create a unique product The result is a homogenous, thermoplastic mass that can be poured directly from the thermo-mixer into prepared lost shells due to its viscosity The result is a homogenous, thermoplastic mass that can be poured directly from the thermo-mixer into prepared lost shells due to its viscosity After a few hours, the trench can be filled again with the original soil After a few hours, the trench can be filled again with the original soil The renovation is then complete. The heating pipes can be used throughout the renovation process The renovation is then complete. The heating pipes can be used throughout the renovation process
