- Improve the energy efficiency of the building
- Reduce transmission of exterior sound to the interior of the building
- Absorb reverberating sounds within the building
- Provide thermal efficiency
- Keep the building warmer in winter and cooler in summer
The closed cell construction has many great features such as soft resistance refractive index, cold resistance, fire-retardant, waterproof, low thermal conductivity, shock and sound absorption and so on. It can be widely used in large-scale central and home air conditioning, construction, chemicals, textile and electrical industries.
