- Utilize as perimeter walls, separator walls or divider partitions between noise sources.
- Use as a liner for interiors of pre-existing enclosures to further reduce noise levels.
- Separate machine or work stations where both sides need sound absorption and noise containment
- Isolate and absorb noise around compressors, punch presses, vibratory bowls, granulators, turning machines or other demanding equipment or processes.
- Use as walls on acoustical enclosures or partitions in manufacturing areas.
- Improve standard doors to keep noise out of office areas adjoined to manufacturing areas
- Can be manufactured with grommets and hook and loop fasteners along each edge for use in acoustical enclosure system.
- Available in 25' rolls with finished or unfinished edges.
Made from quilted vinyl-faced layers of fiber-free willtecŪ foam bonded to both sides of noise barrier material.
