A uncoupling membrane is an innovative functional material used in flooring installations, offering key performance features such as stress isolation, waterproofing and moisture resistance, as well as noise and vibration reduction.
A uncoupling membrane is an innovative functional material used in flooring installations, offering key performance features such as stress isolation, waterproofing and moisture resistance, as well as noise and vibration reduction.
It effectively absorbs substrate movement and stress, significantly lowering the risk of cracking in surface materials—such as tile and stone—caused by substrate deformation.
Additionally, it provides a reliable moisture barrier and minimizes floor vibration and footfall noise, making it widely applicable in residential, commercial, and industrial flooring systems.
Junsheng specializes in the R&D and manufacturing of production equipment for uncoupling membranes.
Holding independent intellectual property rights and multiple core patented technologies, the company is an industry leader in this field.
