About Polymass®
Extruflex proudly presents Polymass, the ultimate soundproofing PVC solution.
Made from specific polymers, this material behaves like a soft viscoelastic mass capable of absorbing sound waves.
Its unique physico-chemical characteristics allow it to better capture sound waves whose energy is then dissipated in the form of micro-heat by a viscous damping phenomenon.
PolyMass is the thin material of reference for the realization of vertical partitions, floors, false ceilings, hotels, houses, technical rooms, industrial premises, special projects; acoustic screens, machine confinement ...
Our comprehensive research has demonstrated that Polymass is capable of reducing sound levels by an impressive 37 decibels, positioning it as an industry pioneer in effectively mitigating noise in heavy-noise environments. Its remarkable sound-absorbing properties enhance the comfort of various settings, making it a staple in numerous global projects, including applications like stadium wall linings and large construction buildings, where sound containment is crucial.
In addition to its soundproofing capabilities, Polymass excels in thermal insulation, enabling sophisticated temperature management within the designated areas
