When it comes to building quieter spaces, whether in multi-family construction, offices, or residential renovations, sound control is expected. And achieving it doesn’t have to mean complicated assemblies or expensive specialty systems.
That’s where TECSOUND CLG 3900 by SOPREMA comes in; a simple, high-performance solution designed to dramatically improve soundproofing in walls and ceilings.
What Is TECSOUND CLG 3900?
TECSOUND CLG 3900 is a solvent-free, single-component acoustic acrylic compound designed to reduce both airborne and impact noise in wall and ceiling assemblies.
Applied between layers of drywall, it acts as a decoupling layer, using the mass-spring-mass principle to disrupt vibration transfer. The result? Less sound moving from room to room—and better-performing assemblies without major design changes.
Built for the Jobsite
One of the biggest advantages of TECSOUND CLG 3900 is how easy it is to work with. There’s no need for specialized equipment or complicated installation methods.
- Applied with a standard caulking gun
- Simple bead pattern on the back of drywall panels
- Installs quickly as part of your normal boarding process
- Works on common substrates like gypsum, OSB, and plywood
Two cartridges per 4′ x 8′ sheet is all it takes to create a high-performing acoustic layer
Real Performance Where It Matters
Soundproofing products need to deliver measurable results, and TECSOUND CLG 3900 does exactly that.
In tested wall assemblies:
- STC improved from 38 to 49 with the addition of TECSOUND CLG 3900
- Vibration transmission was reduced by an average of 13.5%, with peaks up to 33% at certain frequencies
That’s the kind of upgrade that can make the difference between meeting code and exceeding expectations, especially in today’s noise-sensitive environments.
Designed for Real-World Projects
Whether you’re working on new construction or a renovation, TECSOUND CLG 3900 fits seamlessly into your workflow. It’s:
- Ideal for multi-residential, commercial, and retrofit projects
- Low odour and safe to use indoors
- Free of hazardous substances
- Flexible even after curing to maintain long-term acoustic performance
And because it remains soft, it continues to absorb and dampen vibrations over time—unlike rigid materials that can lose effectiveness.
Where It Makes the Biggest Impact
TECSOUND CLG 3900 is especially effective in:
- Party walls between units
- Ceilings in multi-level buildings
- Mechanical rooms and shared service spaces
- Home theatres, offices, and bedrooms
Anywhere noise transfer is a concern, this product adds real value—without adding complexity.
A Simple Upgrade with Big Results
In today’s construction environment, delivering better acoustic performance isn’t just a bonus—it’s a requirement. TECSOUND CLG 3900 offers a straightforward way to elevate your assemblies, improve occupant comfort, and stay ahead of expectations.
