QL Aircraft Noise Control Barriers for Cabin & Structural Noise Reduction
QL Aircraft Noise Control Barrier are advanced, lightweight acoustic barrier materials engineered to reduce airborne noise and structural vibration in business, VIP, and commercial aircraft interiors. Developed by Aaero Technologies (a 3M company), QL materials are purpose-built for aerospace environments where weight control, installation flexibility, and regulatroy compliance are critical.
Designed to perform in confined and complex aircraft structures, QL barries help to create quieter, more comfortable cabins without compromising safety or durability.
Used for:
- Cabin sidewalls, floors, and bulkhead assemblies
- Engine and auxiliary system noise attenuation
- Vibration and airborne noise control in tight aircraft spaces
Why Choose QL Noise Control Barriers?
QL material is engineered specifically to meet the performance and safety demands of aerospace applications.
Lightweight, Aerospace-Grade Construction
QL barriers provide effective noise attenuation while minimizing added weight—an essential consideration for aircraft performance and fuel efficiency.
Thermoset Dimensional Stability
The thermoset construction delivers superior dimensional stability, maintaining shape and integrity across a wide range of temperatures and mechanical stresses commonly found in aircraft environments.
Flexible for Complex Installations
QL material remains flexible enough to conform to irregular surfaces and tight installation spaces, enabling precise fitment in aircraft structures and interior assemblies.
FAR 25.856(a) Flammability Compliance
All QL aircraft noise control barriers fully comply with FAR 25.856(a) flammability requirements, supporting certification and regulatory compliance for aerospace programs.
Selecting the Right QL Material
QL noise control barriers are available in multiple thicknesses and formats to support different acoustic performance targets and installation requirements.
Barrier thickness selection depends on:
- Target noise frequencies
- Available installation space
- Weight and performance constraints
- Use of pressure-sensitive adhesive (PSA)
If you’re unsure which option is best for your application, our aerospace materials specialists can help guide material selection.
