SilentCloud® ProMass 50 – Non-Adhesive Acoustic Membrane
High-Density Soundproofing Barrier for Walls, Ceilings & Floors (5 kg/m²)
SilentCloud® ProMass 50 is a professional-grade, non-adhesive acoustic membrane engineered to add mass, damp vibration and significantly reduce airborne and impact noise when used as part of a soundproofing system.
Designed for installers, contractors and serious DIY soundproofing projects, ProMass 50 delivers the same high-density visco-elastic performance found in industry-leading membranes — without branding dependency or inflated marketing claims.
**Key Benefits**
• True high-mass performance – 5 kg/m² density for effective sound blocking
• Non-adhesive format – ideal for decoupled systems and mechanical fixing
• Ultra-thin profile – adds mass without stealing room space
• Excellent vibration damping – reduces resonance in lightweight structures
• Fire rated (Euroclass B-s2,d0) – suitable for residential & commercial use
• Flexible & easy to install – wraps around corners, studs and services
• Moisture, rot & mould resistant – long-term stability guaranteed
**Typical Applications**
Construction uses:
• Stud walls & partition walls
• Ceilings & suspended ceilings
• Timber & metal frame systems
• Between plasterboard layers
• Under floating floors & screeds (system dependent)
Industrial & specialist uses:
• Damping metal panels and decks
• Plant rooms & machinery enclosures
• Drainpipes & ductwork (with absorbent layers)
• Reducing rain noise on metal roofs

**How SilentCloud® ProMass 50 Works**
Sound travels through lightweight structures easily. ProMass 50 works by:
1. Adding mass to reduce airborne sound transmission
2. Damping vibration to control resonance and structure-borne noise
3. Working with absorbent layers (mineral wool, acoustic slabs) to create a mass‑spring‑mass system
**Recommended System Use (Important)**
For best results, SilentCloud® ProMass 50 should be used as part of a complete soundproofing system, typically:
– Plasterboard
– SilentCloud® ProMass 50
– Acoustic mineral wool
– Plasterboard/resilient system
Used correctly, this delivers far greater performance than membrane-only installations.
**Installation Notes**
– Cut with a sharp utility knife
– Fix using mechanical fixings, battens or sandwich between boards
– Overlap joints and seal where required
– Always avoid rigid mechanical bridges
Professional installation recommended for regulated environments.
**Why SilentCloud® Beats Branded Alternatives**
Most competitors sell the same technical membrane under different names—but fail to explain how to use it correctly. SilentCloud® delivers clear system guidance, honest specifications, installer-first product design, no misleading “single-product dB claims” and better trust.
**Frequently Asked Questions**
Q: Is this the same as Tecsound 50?
A: SilentCloud® ProMass 50 matches the same density, thickness and performance class, without paying for brand licensing.
Q: Is this self-adhesive?
A: No. This is the professional non-adhesive version, preferred for decoupled systems and long-term stability.
Q: Can I use it on its own?
A: No acoustic membrane should be used alone. It must be combined with boards and absorbent layers for real results.
Q: Does it stop impact noise?
A: When used in flooring systems, it helps reduce vibration and impact transmission as part of a compliant build‑up.
