SECTION 09722
WALL FABRICS
NOTE ** Carnegie; Xorel and Xorel Two fabrics for wall
covering and upholstery.
NOTE **
NOTE ** This section is based on products manufactured by
Carnegie, located at the following address:
NOTE ** Carnegie
NOTE ** 110 North Centre Avenue
NOTE ** Rockville Centre, NY 11570
NOTE ** Tel: (800) 727-6770
NOTE ** Fax: (516) 678-6848
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.
