Composite Sound Insulation Board
SG-E17 composite sound insulation board with an IIR damping layer between high-density Calcium Silicate layers. Supplier laboratory result: Rw 33 dB for the tested sample. Installed performance depends on the complete assembly and installation.
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 + 1 + 8 configuration, giving a total thickness of 17 mm.
The damping layer selection of 1mm IIR (Isobutylene-Isoprene Rubber) 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 Rw 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
- 1mm IIR Damping Layer - Absorbs vibration and disrupts sound transmission
- 8mm Calcium Silicate (CS) - Second high-density layer for enhanced performance
This 8+1+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
- Reaction to Fire: B1 under GB 8624-2012
- Durable Construction: High-density Calcium Silicate ensures long-lasting performance
- Compact Design: Only 17mm thick, minimizing space loss while maximizing performance
Technical Innovation
The IIR 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.
Recommended Applications
SG-E17 is specifically designed for high-noise environments requiring superior sound isolation:
- Entertainment Venues: KTV rooms, nightclubs, karaoke lounges
- Performance Spaces: Cinemas, theaters, auditoriums, concert halls
- Professional Studios: Recording studios, broadcast facilities
- Sports Facilities: Indoor stadiums, gymnasiums
- Residential: Home theaters, home karaoke rooms
