Environmental Noise Control, Inc.’s STC-25 Acoustic Blankets are manufactured using state-of-the-art acoustical composite materials with an engineered design.

ENC’s STC-25 acoustic blankets are designed to provide optimum sound control for blocking and absorbing unwanted noise. In addition, they have been tested by an independent acoustical laboratory per ASTM E-90 and ASTM E-413 requirements and have a verified sound transmission loss.

ENC’s acoustic blankets are fabricated with a proprietary polyvinyl-chloride-coated outer shell, noise-absorbing and blocking material, and an engineered inner core with an X-5 septum barrier.
