GrüTech energy-saving product
Rigid polyurethane's first application in floor heating thermal insulation in China


GrüTech polyurethane energy-saving floor heating thermal insulation products are new energy-saving floor heating thermal insulation materials researched and developed by Liheng Group in cooperation with Huntsman (U.S.) and Hennecke (Germany), two leaders in the polyurethane industry. The product is called in the industry the fourth-generation superconducting thermal insulation material in the history of floor heating thermal insulation technologies.




Thermal insulation materials
are the key determining the energy-saving performance of the floor heating system 


The significance of thermal insulation materials has been ignored in the floor heating system. In fact, the performance of thermal insulation materials determines the use ratio of heat of the floor system as well as the energy-saving index of the whole floor heating system. GrüTech energy-saving floor heating thermal insulation board using polyurethane as its core materials is a complete revolution of the energy-saving technology.




Development history of floor heating thermal insulation materials

The first generation: EPS
The second generation: XPS
The third generation: Superconducting XPS
The fourth generation: PU (rigid polyurethane)



Renovation in China's floor heating thermal insulation industry driven
by advanced technologies from Europe and America


GrüTech polyurethane energy-saving floor heating thermal insulation products have a performance higher than the third-generation materials, XPS, in terms of thermal insulation, watertightness, moisture proofness, fire resistance, energy conservation and environment protection, etc. The energy consumption is significantly reduced by 50% compared with the traditional floor heating thermal insulation materials and the heating efficiency is enhanced to an unprecedentedly high level, which is of epochal significance for the development of the floor heating industry and the advance of heating technologies.
