See how ProSilence U-Boats dampen vibrations!
The video demonstrates how DreamScreen U-Boats effectively decouples the floor structure using soft silica gel for maximum sound insulation. The vibrations are transferred to water in the demonstration to visualize how the system works.

🌟 DreamScreen ProSilence U-Boat v2 🌟
ProSilence U-Boats are designed for true structural decoupling of floor structures and represent a completely different principle to traditional impact sound panels. They are used in home cinemas, studios and other rooms where low-frequency structural sound and vibrations need to be effectively stopped.
⚖️ ProSilence U-Boats vs. traditional impact sound panels
Traditional impact sound panels act as a compressible layer in a floating floor. They can reduce mid- and high-frequency impact sound, but have limited effect in the bass range, where heavy walking and vibrations are most annoying.
This is because stepped sound panels have relatively high dynamic stiffness, which means that the system’s natural resonance often ends up in the 40-100 Hz range. In this range, vibrations can in practice propagate further – and in some cases be amplified.
ProSilence U-Boats, on the other hand, are designed as a spring-based decoupling system, not a compressible underlay:
- Made of low-density silica gel with real spring function
- Large permissible elastic travel under load
- Intrinsic resonance of the system ≈ 10 Hz
This means that ProSilence U-Boats provide effective insulation throughout the critical low-frequency range (20-80 Hz), where impact sound panels in practice have little or no effect.
The result is a floating floor construction that:
- Reduces heavy step sound (“thump”)
- Limits low-frequency structure-borne sound
- Prevents vibrations from propagating to the rest of the building
This graph shows the typical effect of a spring-coupled approach used by our U-boats and vs. a typical solution based on step sound plates
🔍 What makes the v2 version special?
- Made from exclusive silica gel – softer than rubber and far more effective at absorbing vibration energy 🎧
- Designed for standard 48 mm studs 🛠️
- Long life, durable and temperature resistant ♻️
- RED series available – extra soft silica gel for particularly demanding installations
⚙️ How does it work?
The U-Boat is installed under the studs in the floor structure and forms a resilient separation between the new floor and the existing joists. The floor is supported mechanically, but at the same time effectively decoupled structurally.
Unlike stepped sound panels, which mainly work via natural resonance, ProSilence U-Boats provide real vibration isolation already in the bass range.
📌 Advantages
- Real spring-based floor decoupling 🔇
- Proven efficiency in the low frequency range
- Made from specially developed silica gel – softer and more effective than rubber
- Fits standard steel and wood studs (48 mm)
- Cost-effective solution for home cinema and studio
- Easy installation without special tools 🧰
Result: A stable, floating floor structure that effectively prevents vibration noise and low-frequency energy from spreading throughout the building – and provides a far better acoustic end result than traditional impact sound panels.
