SilentCloud™ ProMass 50 – Self-Adhesive Acoustic Membrane (2.6 mm)

High-Density Soundproofing Barrier | ~5 kg/m² | Professional Grade

Reduce airborne noise properly with SilentCloud™ ProMass 50 — a high-density, polymer-based acoustic membrane engineered to block sound transmission through walls, ceilings, and partitions without adding unnecessary thickness.

At just 2.6 mm thick, SilentCloud™ ProMass 50 delivers an impressive ~5 kg/m² of controlled acoustic mass, making it ideal for space-restricted renovations, refurbishments, and professional soundproofing systems.

✔ High-Density Acoustic Barrier – ~5 kg/m² surface mass reduces airborne noise effectively
✔ Ultra-Slim 2.6 mm Profile – Powerful soundproofing without sacrificing room space
✔ Self-Adhesive Installation – No wet glue, no curing time, cleaner and faster fitting
✔ Visco-Elastic Damping Layer – Suppresses vibration in plasterboard and rigid panels
✔ Over-Board Immediately – Install and finish the same day

What This Product Does

• Increases surface mass to reduce airborne sound transmission

• Dampens vibration in rigid materials such as plasterboard

• Improves sound insulation in walls, ceilings, stud partitions, and layered floor build-ups

• Enhances performance when used within a complete soundproofing system

• Why Choose SilentCloud™ ProMass 50?
  SilentCloud™ ProMass 50 is engineered to deliver high acoustic mass in a slimmer, more controlled format. Manufactured to tight density tolerances, it provides consistent, predictable performance across every roll — without unnecessary thickness, odour, or installation complexity.

Why SilentCloud™ ProMass 50 Works Better

Many constructions transmit noise because rigid boards vibrate and re-radiate sound energy. SilentCloud™ ProMass 50 solves this by combining very high mass with visco-elastic flexibility.

This allows it to:

• Suppress vibration rather than amplify it

• Maintain performance without increasing wall thickness

• Conform tightly to substrates for continuous acoustic coupling

Manufactured to tight density tolerances, every roll delivers consistent, predictable performance — not the variability found in commodity membranes.

Key Benefits (Quick to Scan)

Important Performance Notes

• Designed primarily for airborne noise reduction

• Not a standalone impact-noise solution

• Best results achieved as part of a complete soundproofing system

• Acoustic performance depends on construction type and installation quality

Why Choose SilentCloud™ ProMass 50?

SilentCloud™ ProMass 50 delivers serious sound control in a slimmer, more controlled format, making it the professional choice for projects where space efficiency, reliability, and predictable results are essential.

This is professional soundproofing done properly — without unnecessary thickness, mess, or compromise.

Frequently Asked Questions – SilentCloud™ ProMass 50

Will SilentCloud™ ProMass 50 completely soundproof a room?

SilentCloud™ ProMass 50 is designed to significantly reduce airborne noise, not to create total silence on its own.
For best results, it should be used as part of a complete soundproofing system alongside plasterboard, insulation, or resilient components. When installed correctly, it provides a substantial and noticeable improvement in sound reduction.

Is SilentCloud™ ProMass 50 suitable for DIY installation?

Yes. SilentCloud™ ProMass 50 is DIY-friendly, thanks to its self-adhesive backing and flexible construction.
No specialist tools are required — a utility knife and roller are sufficient. Professional installers also use this product due to its speed, cleanliness, and predictable performance.

Can I use SilentCloud™ ProMass 50 on walls, ceilings, and floors?

SilentCloud™ ProMass 50 is ideal for walls, ceilings, stud partitions, and layered floor build-ups where airborne noise reduction is required.
For floors, it must be used within a layered system and is not a standalone impact-noise solution. For impact noise, resilient layers or acoustic flooring systems should be added.

Do I need to cover SilentCloud™ ProMass 50 with plasterboard?

For optimal acoustic performance, yes.
SilentCloud™ ProMass 50 is designed to be over-boarded with plasterboard or other finishing layers, forming part of a mass-spring-mass system. This dramatically improves sound reduction compared to using a membrane alone.

How many rolls do I need?

Each roll covers approximately 7.2 m².
Measure the surface area of the wall or ceiling you are treating and divide by 7.2 to determine the number of rolls required. If you are unsure, our technical team can help you calculate coverage accurately.

Is SilentCloud™ ProMass 50 safe for residential use?

Yes. SilentCloud™ ProMass 50 uses a low-odour, asphalt-free formulation, making it suitable for internal residential and commercial environments once installed behind finishes.

What type of noise does this product reduce best?

SilentCloud™ ProMass 50 is optimised for airborne noise, such as voices, television, music, and general room-to-room sound transmission.
It works by adding dense mass and damping vibration in rigid surfaces like plasterboard.

Can SilentCloud™ ProMass 50 be repositioned once applied?

Due to its high-tack self-adhesive backing, repositioning is limited once firmly pressed into place. We recommend dry-positioning and alignment checks before applying full pressure.
