-
- NOTE ** Introduced in 1981 after seven years of research
- and testing, Xorel fabrics have revolutionized the
- interiors of public spaces. They combine
- performance qualities essential for high traffic
- areas with the aesthetics of woven textiles. Xorel
- fabrics are exceptionally stain resistant and can
- be cleaned easily with a cloth dipped in hot water.
- They are remarkably durable, acoustically
- transparent, colorfast, antibacterial,
- environmentally safe, and meet strict flame
- retardancy requirements.

- C. Stretched Installation: Over acoustical panels, install
- fabric in accordance with panel manufacturer's
- instructions.
- 1. Provide seam allowances of at least 1/2 inch (13 mm).
