The Science of
Silence
How sound insulation, vibration damping, and acoustic absorption work together to deliver complete noise control.
The Three Challenges of Sound Control
Every acoustic environment faces three distinct problems. Each requires a different engineering solution and different materials.
Airborne Sound
Sound transmitted through the air - voices, music, bass frequencies. Requires high-density mass barriers to block energy from passing between spaces.
Key Metric
Up to 38 dB
Brochure Sound Reduction Index (Rw) · SG-F12-2
Structure-Borne Vibration
Vibrations travelling through walls, floors, and ceilings. Requires mechanical decoupling - isolating structures so vibration energy cannot transfer between elements.
Key Principle
Vibration isolation
Low-frequency control
Room Acoustics
Internal reflections creating echo and reverberation. Requires porous absorption materials that convert sound energy into heat, reducing reverb time and improving clarity.

Mass-Spring-Mass Principle
Our core insulation technology relies on the Mass-Spring-Mass physical law. By sandwiching a viscoelastic IIR damping layer (the spring) between high-density boards (the mass), we effectively decouple the structure and prevent sound transmission.
When sound waves hit the first mass layer, they cause vibration. As this energy travels through the IIR damping core, it is converted into minute amounts of heat energy through shear deformation - significantly reducing the energy that reaches the second mass layer.
- Dissimilar Mass Layers
Different board materials prevent resonance coupling
- IIR Damping Core
Viscoelastic rubber converts vibration to heat
- Energy-to-Heat Conversion
Sound energy is dissipated, not reflected or transmitted
"Every layer has a purpose. Every material is chosen for its acoustic contribution."
Three Boards, Three Configurations
Each board combines different mass layers with IIR damping for specific performance characteristics.

Vibration Isolation Principle
Structure-borne vibration is the most challenging acoustic problem. When bass frequencies cause walls, floors, and ceilings to vibrate, the entire building structure becomes a speaker - transmitting noise to every connected room.
Damping products use spring-loaded and viscoelastic components to reduce vibration transfer. Structural decoupling reduces rigid transmission paths between building elements.
Viscoelastic materials dissipate vibration energy as heat. The loss factor describes how effectively a material dissipates that energy: a higher loss factor means vibration decays faster. Material damping and structural decoupling complement each other.

- Viscoelastic mats for surface-level damping
- Speaker pads to isolate subwoofer vibration

Porous Fibre Absorption
When sound enters a room, it bounces off hard surfaces creating echo and reverberation. Absorption panels solve this by converting reflected sound energy into heat through friction within a porous fibre network.

The Final Seal
Even the best insulation system fails if gaps remain. Sound travels through the path of least resistance - a 1% gap in coverage can transmit up to 50% of sound energy. Acoustic sealant closes every joint, edge, and penetration point to ensure the system performs as designed.
SG-AS65 is a flexible sealant for gaps and joints. The supplier laboratory result is Rw 31 dB for the tested sealed assembly (J25C063552100BR); this is not a noise reduction rating for sealant alone.
