Sound InsulationSG-E17
Composite Sound Insulation Board
High-performance composite damping sound insulation board with EPDM damping layer sandwiched between high-density Calcium Silicate layers. Achieves 33dB sound reduction. Ideal for KTV, cinemas, studios, and entertainment venues.
Product Description
SG-E17 is a composite damping sound insulation board designed according to the transmission characteristics of sound. The material consists of three layers arranged in an 8 + 2 + 8 configuration, giving a total thickness of 18 mm.
The damping layer selection of 2mm EPDM (Ethylene Propylene Diene Monomer) is sandwiched between 2 layers of 8mm high-density CS (Calcium Silicate), creating a structure that delivers outstanding acoustic performance.
The system disrupts multiple sound frequencies and increases STC (Sound Transmission Class) performance, making it the ideal choice for entertainment venues, recording studios, and any space requiring superior sound isolation.
Product Engineering Principle & Performance

Product Engineering Principle
The SG-E17 utilizes a sophisticated three-layer construction that maximizes sound isolation:
- 8mm Calcium Silicate (CS) - High-density outer layer provides mass and rigidity
- 2mm EPDM Damping Layer - Absorbs vibration and disrupts sound transmission
- 8mm Calcium Silicate (CS) - Second high-density layer for enhanced performance
This 8+2+8 configuration effectively disrupts multiple sound frequencies, particularly effective against low to mid-frequency sounds that typically penetrate standard building materials.
Why Choose SG-E17?
The SG-E17 represents the pinnacle of composite damping technology, engineered specifically for spaces that demand exceptional sound isolation.
Key Benefits
- Superior Sound Isolation: Achieves 33dB Reduction Index (Rw), effectively blocking significant noise transmission
- Versatile Installation: Can be cut with saw, drilled, and secured with self-tapping screws
- Multiple Finish Options: Compatible with wallpaper, glass, tiles, and cement finishes
- Fire Safe: Class A non-combustible rating for peace of mind
- Durable Construction: High-density Calcium Silicate ensures long-lasting performance
- Compact Design: Only 18mm thick, minimizing space loss while maximizing performance
Technical Innovation
The EPDM damping layer acts as a vibration absorber, converting sound energy into minimal heat energy. This damping effect is particularly effective against low to mid-frequency sounds that typically penetrate standard building materials.
Installation Methods
SG-E17 can be installed using standard construction methods:
- Direct mounting with self-tapping screws to metal or wood studs
- Adhesive application combined with mechanical fastening
- Framework mounting for suspended ceiling applications
The board can be easily cut to size using standard carpentry tools, making it adaptable to various project requirements.
