QL Noise Control Barrier

QL Noise Control Barrier material from Aearo Technologies 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. 54" width in two thicknesses, with or without PSA (PSA700). Includes FAA burn certificate for FAA 25.853(a) Vertical Burn. Quantities over 10' require a Special Order. Contact us for more information. Sold in foot-lengths, 10' rolls, or 150 rolls for certain variants.
