QL Noise Control Barrier
SKU# QL20-54-1
QL Noise Control Barrier material is a low surface weight, high-performing noise control barrier for aircraft applications. This thermoset barrier is specifically engineered for high dimensional stability, flexibility, damping and to comply with FAR 25.856(a) flammability—and is incidentally waterproof.
Sold by the foot with a 54" width in two thicknesses, with or without PSA. Includes FAA burn certificate for FAA 25.853(a) Vertical Burn.
Quantities over 10' require a Special Order. The lead time for Special Orders is 6-9 weeks, or 8-11 weeks for PSA-backed products. Contact us for more information.
Est. lead time: 6-9 weeks
