Features

workimg


High Performance in Noise Reduction

Durksonic QEP is flexible open cell material with unique compound structure, when the acoustic waves enter the material, it will collide several times, and because of the elasticity of the material, the sound energy will be absorbed. There would be better performance of acoustic insulation.

workimg


Environmental friendly

Open cell, fiber free and dust free, resistant to the growth of mold and fungi, the Durksonic QEP can effectively prevent the breeding of bacteria and ensure a healthier environment.

workimg


Longer Life Span

High hydrophobic. It’s unnecessary to do the process of waterproof and moisture proof. Moreover, high water vapor diffusion resistance prolongs the life span.

workimg


Easy installation

Because of moderate density and flexibility, Durkflex QEP can be easily cut and transported conveniently. And fiber free, dust free, it would be safer and more economical to be applied in sound blocking works.
