kumikerros
Kumikerros is a Finnish term referring to a layer primarily composed of rubber or elastomer intended to provide elasticity, damping, and movement accommodation in various engineering contexts. The concept is used to improve comfort, reduce transmission of vibrations and sounds, protect against moisture, and accommodate differential movement between connected surfaces.
Materials and properties commonly involved include natural rubber, synthetic rubbers (such as SBR, EPDM, or neoprene),
Applications of kumikerros span several sectors. In construction and flooring, a kumikerros acts as an underlayment
In Finnish technical literature, kumikerros is described as a versatile elastic layer suited to compensating movement,
