Closed-cell – high-performance insulation materials for technical sound insulation
The term closed-cell describes the structure of a foam in which the cells are completely sealed off from each other. This closed cell structure makes the material impermeable to water and air, making it ideal for sound insulation, thermal insulation and vibration damping in machines and vehicles.
Closed-cell sound insulation materials such as PE foam (polyethylene) or NBR foam (nitrile rubber) offer excellent structure-borne sound insulation as they effectively dampen and isolate vibrations and minimise sound transmission through solid components.
Properties of closed-cell foams
- High sound insulation – ideal for reducing structure-borne noise and vibrations
- Water and moisture resistant – perfect for damp rooms and technical applications
- Chemical resistant – resistant to fuels and industrial substances
- Durable and robust – dimensionally stable and resistant to mechanical stress
