Since the ancient Greeks the golden ratio has been considered a visually pleasing proportion. We agree, and designed this stock size to be proportioned according to the golden ratio, while at the same time sticking to even foot increments for ease in combining this size with our other stock sizes in patterns and layouts.
Features and Benefits of ATS Hardened-Edge Acoustic Panels
- Panels conform to the industry specifications and standards most commonly used by architects—no guesswork, no surprises.
- Lightweight, frameless panels have a rigid fiberglass core (6 pound per cubic foot density), extremely effective at absorbing sound.
- High Noise Reduction Coefficient (NRC) means exceptional sound absorption and the need for fewer panels.
- Fabric is tightly and evenly stretched around the core to prevent visual imperfections such as puckers or wrinkles.
- Borders are treated to form durable, impact-resistant edges.
- Panels are handcrafted in the USA to ensure the highest quality construction.
- Guilford of Maine is the industry standard in acoustic fabric with an ASTM E84 Class A fire rating and a sleek, commercial-grade polyester weave.
- Panels are easy to install on a variety of surfaces and leave little damage when removed—no more than hanging a picture.
- Multiple installation options available for all of your project needs.
- We offer custom shapes and sizes built to your specifications.
