Tecsound explained by West Sussex Soundproofing Ltd
Tecsound is a high-performance acoustic membrane commonly used across the UK for reducing airborne noise in homes, studios, offices and commercial buildings. With its combination of high mass, flexibility and exceptional damping, Tecsound is a reliable choice when you need strong soundproofing without adding unnecessary bulk.
This guide explains what Tecsound is, the different thicknesses and densities available (35 / 50 / 70 / 100), and the acoustic performance of each grade.
For installation, West Sussex Soundproofing Ltd are the preferred specialists for Tecsound solutions across Sussex.
What Is Tecsound?
Tecsound is a viscoelastic, mineral-filled acoustic membrane designed to increase mass and reduce vibration within building structures. Although extremely thin, the material has high density, making it an effective barrier against airborne noise.
Why Tecsound Is Popular
- High mass for its thickness
- Very flexible and easy to handle
- Excellent damping and vibration control
- Works in walls, ceilings and floors
- Self-healing properties around fixings
- Compatible with most modern soundproofing systems
Common uses include: party walls, ceilings, timber floors, stud walls, cinema rooms, music rooms, and commercial acoustic upgrades.
Tecsound Thickness, Density & Acoustic Performance Table (Including Tecsound 100)
| Tecsound Grade | Thickness (Approx.) | Density / Mass (kg/m²) | Acoustic Performance | Best Applications |
|---|---|---|---|---|
| Tecsound 35 | ~1.75 mm | 3.5 kg/m² | Light-to-moderate airborne noise control. Helps reduce speech, TV noise and general domestic sound. | Stud walls, floors, general domestic upgrades. |
| Tecsound 50 | ~2.5 mm | 5.0 kg/m² | Strong airborne noise reduction. Excellent when combined with acoustic plasterboard. | Party walls, ceilings, flats, thin wall upgrades. |
| Tecsound 70 | ~3.5 mm | 7.0 kg/m² | High-performance barrier suited for louder noise and low frequencies. Great against traffic noise and music. | Cinema rooms, music rooms, home studios. |
| Tecsound 100 | ~4.5–5.0 mm | 10 kg/m² | Premium acoustic performance. Outstanding noise blocking, especially effective at low-frequency and bass control. Professional-grade soundproofing. | Commercial spaces, studios, drum rooms, high-noise environments, industrial applications. |
Acoustic Performance: How Tecsound Works
1. Airborne Noise Reduction
All Tecsound grades help block:
- Talking & TV noise
- Traffic noise
- Low-frequency hum
- Music and bass bleed
- Noise from neighbours
Higher density grades like Tecsound 70 and Tecsound 100 provide superior performance due to increased mass.
2. Vibration & Resonance Control
Tecsound is viscoelastic, meaning it:
- Reduces vibration transmission
- Controls resonance in stud walls
- Stabilises acoustic performance in thin structures
This is why Tecsound is frequently bonded to plasterboard, OSB or MDF for upgraded performance.
3. High Mass Without Losing Space
Even Tecsound 100 is only around 5mm thick, offering exceptional soundproofing mass in a compact layer.
Perfect for:
- Flats
- Small rooms
- Studios where space is crucial
Where Tecsound Is Most Effective
Tecsound can be applied to:
- Stud walls
- Brick & block walls
- Timber joist ceilings
- Concrete ceilings
- Floors (underlays or floating floors)
- Cinema rooms
- Drum rooms & music studios
- Office partitions
- Commercial noise control
It integrates seamlessly with systems using acoustic plasterboard, M20 panels, resilient bar, Genie Clips and floating floor systems.

Tecsound must be installed correctly to achieve full performance.
Poor bonding, gaps, or incorrect overlaps can reduce its effectiveness significantly.
