The barrier septum configuration offers the benefits of both sound absorption and noise barriers. All Noise Control’s ANC-AB12 consists of a non-reinforced 1-lb psf loaded vinyl noise barrier sandwiched between two layers of vinyl-coated-fiberglass-cloth faced 1” quilted fiberglass sound absorbers.
Applications:
Typical uses include curtain panels in acoustical curtain enclosures. Also used as separator walls or divider partitions between noise sources. Commonly used to line the perimeter walls of a building, or as a free-hanging noise barrier/sound absorber wall.
