Sound Barrier Blankets for Noise Mitigation
QBS Blankets are designed to both absorb and block sound, making them an ideal solution for reducing noise levels within a space and preventing sound transmission. These durable, flexible composite blankets feature a barrier septum design, combining quilted fiberglass for absorption with a mass-loaded vinyl barrier for blocking sound.
Common Uses Include:
✔️ Lining walls and ceilings to control noise within a room and prevent sound transmission.
✔️ Enclosing noisy equipment with curtain panels or partitioning spaces.
✔️ Hanging as free-standing barriers to separate loud areas from quiet spaces.
Available in multiple variations, QBS Blankets can be customized to meet your noise control needs. Contact us if you need help choosing the appropriate model for your project or application.

Soundproofing Factory Noise: Targeting 85 dBA for Worker Safety
In industrial environments, the goal is clear—reduce noise exposure to below 85 dBA to protect your workforce and meet OSHA standards. The most effective strategy starts at the source of the noise. Rather than only treating perimeter walls or ceilings with sound panels, first focus on enclosing the equipment generating the noise.
While acoustic panels help minimize echo and reverberation, they do not block the original sound energy. That’s where QBS sound barrier blankets come in. These composite blankets both block and absorb sound, making them ideal for surrounding loud machinery, compressors, generators, or pumps.
Be proactive and creative—use QBS blankets to build enclosures, curtain systems, or partial barriers around noise sources. This approach significantly reduces direct sound exposure and limits how much noise reflects into the rest of the workspace.
Actual decibel reduction will vary based on several factors: starting dB levels, noise frequency, floor vibration, enclosure design, surrounding surfaces, and more. But with proper application, QBS blankets can help bring your facility’s noise levels down below the 85 dBA threshold.
Compared to rigid metal enclosures, QBS blankets offer a flexible, cost-effective alternative that’s easier to install, modify, and maintain.
Shipping
QBS Blankets are packaged and shipped in boxes shrunk wrap on a pallet. Depending on the size of your order, the blankets will typically ship via common carrier direct to your project site.
