TECSOUND CLG 3900 Compound: High-Performance Soundproofing and Acoustic Damping Solution

TECSOUND CLG 3900 Compound is a high-quality soundproofing and vibration damping compound used to control unwanted noise in a wide range of spaces. It is designed for both new builds and retrofit projects, helping to create quieter, more comfortable, and more private environments.

This flexible viscoelastic compound works by converting sound energy into low-level heat, which significantly reduces vibration and resonance through walls, ceilings, and floors. As a result, it helps improve Sound Transmission Class (STC) ratings and overall acoustic performance. Whether you are soundproofing a condo, office, or recording studio, TECSOUND CLG 3900 delivers proven, professional results.

Superior Soundproofing and Acoustic Performance

When applied between layers of drywall or other materials, TECSOUND CLG 3900 forms a dense, vibration-damping layer that reduces the transfer of sound and impact noise. It performs especially well when paired with  TECSOUND CLG 5900 Sealant creating a complete system that enhances both sound isolation and comfort.

Because of its flexibility and strong adhesion, TECSOUND CLG 3900 can be used in commercial, industrial, and residential projects alike. Moreover, it maintains its performance even in changing temperatures, making it a dependable choice for long-term acoustic control.
