FLEX AL SA
Product Description
FLEX is a line of soundproofing materials based on elastomer rubber and mineral-polymeric membrane of high density. The combination ensures maximum effciency in noise reduction at minimum thickness of the material. The product is excellent solution for soundproofing of utility systems and services including ventilation ducts. The material is easy to cut and work with, health friendly.
The product has an additional layer of aluminum foil for protection of mechanical damage and aggressive external environment.
Composition
- soft layer: foam rubber
- dense layer: membrane based on polymers, high-density rubber, and mineral components (baryta)
- aliminum foil
