High-Mass Sound Deadening Panels for True Noise Control
🧱 Overview
Pure Pressure VibraFlex 190 and 225 are premium self-adhesive sound deadening panels made from a flexible, high-density bitumen compound. Designed to dramatically reduce both structure-borne vibration and airborne noise, these sheets are ideal for automotive floors, wheel wells, speaker enclosures, industrial machinery housings, and marine engine rooms.
Each sheet uses a viscoelastic polymer bitumen core with an acrylic adhesive backing and a protective polyethylene (PE) top film. Together, this multi-layer design transforms noisy, resonant panels into quiet, solid-feeling surfaces.
🔧 Product Specifications
Property | VibraFlex 190 | VibraFlex 225 |
Thickness | 4.9 mm (0.190") | 5.7 mm (0.225") |
Weight | 2.04 lb/ft² | 2.45 lb/ft² |
Adhesive | Solvent-free acrylic | Solvent-free acrylic |
Top Layer | Polyethylene (PE) film | Polyethylene (PE) film |
Color | Black | Black |
These sheets are easy to trim and install using a heat gun / torch and roller. Once applied properly, they bond securely and don’t sag, soften, or peel under normal use conditions.
🔊 Sound Insulation Performance (dB Gain Over Bare Steel)
Frequency (Hz) | Untreated Steel (dB) | VibraFlex 190 (dB) | VibraFlex 225 (dB) |
100 Hz | ~22 | ~30 | ~32 |
200 Hz | ~28 | ~39 | ~41 |
400 Hz | ~35 | ~50 | ~52 |
800 Hz | ~41 | ~56 | ~57 |
1600 Hz | ~47 | ~60 | ~61 |
3200 Hz | ~51 | ~62 | ~62 |
📌 What this means:
These panels significantly improve sound isolation when bonded to thin metal. At key frequencies like 200–800 Hz (where road noise, exhaust, and engine vibration live), VibraFlex delivers up to 30–40 dB of improvement, turning tinny, rattling metal into dense, dead silence.
📉 Damping Performance – Loss Factor at 200 Hz
Temperature (°C / °F) | VibraFlex 190 | VibraFlex 225 | Description |
20°C / 68°F | 0.12 | 0.14 | Room temperature performance |
40°C / 104°F | 0.24 | 0.28 | Warmed-up panels |
60°C / 140°F | 0.35 | 0.40 | Ideal temperature range |
📌 What this means:
Loss factor (η) is a measure of how well the material converts vibration into heat. Higher values mean better damping. When properly heated before installation, both 190 and 225 deliver powerful resonance control at low frequencies.
🔥 Durability & Resistance
Property | Value |
Continuous Temp Limit | 176°F |
Short-term Exposure | 356°F |
Fire Classification | EN 13501 Class E, FMVSS 302 |

Oil Resistance | Excellent |
🛠️ Installation Tips
Clean the surface with isopropyl alcohol or acetone. Surface must be free of rust, oil, and debris.
Preheat panels to 140–175°F using a torch or heat gun for best adhesion and flexibility.
Roll firmly using a deadener roller for full contact (try our Ultimate Deadener roller!)—start in the center and work outward.
Burn off PE liner if layering two sheets; wipe off soot / clean previous layer before applying second layer.
