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.

NOTE **
NOTE ** Xorel fabrics are now produced in three different types of Xorel yarn: Classic Xorel, Classic Xorel IFR, and Xorel Two. Classic Xorel IFR has been modified to be inherently flame resistant and is used to produce the Meteor 6427 pattern. Xorel Two is a finer yarn than the original, Classic Xorel, and is inherently flame retardant.

5. Do not use seam roller of any type at seams or edges; smooth seams with plastic scraper.
6. Horizontal seams are not acceptable.
7. Do not seam within 2 inches (50 mm) of internal and external corners.
8. Remove excess adhesive from seam while wet, using slightly damp sponge and clean, hot water. Dry immediately with clean terry towel.
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).
2. Top stitch seams for additional strength.
3.4 ADJUSTING, CLEANING, AND PROTECTION
