NE Spray On is a total system of recycled natural fibers, chemical treatment, binding system and application method. During application, the fibers are combined with a patented adhesive. The finished product is a strong, durable monolithic coating of a predetermined thickness.

The resilient fibers of NE Spray On absorb sound energy instead of reflecting it, reducing reverberation time. Excessive noise is reduced with the application, while greatly improving ambient sound quality.

NE Spray On is the spray-applied tailored to your specific project requirements. Meets specifications for insulation (R-value), noise reduction (NRC), color, durability, condensation control, texture, and aesthetics.  Additionally, provides these features at lower installed prices than many common alternatives.

NE Spray On serves as an exposed finish requiring no additional materials. It is applied to virtually any properly prepared surface and configuration. Can be sprayed up to 5″ thick in one application without mechanical support. Available in a wide variety of colors.
