At iStudio Projects, our Rose Brand 22 oz. Encore Velour (SKU # VL220001βVL220020) is a premium Inherently Flame Resistant (IFR) performance fabric engineered for theatrical draperies, stage curtains, and acoustic panels in demanding performance environments. Unlike woven velours, the Encore features a knit construction from 100% IFR polyester with a napped finish β delivering exceptional acoustic performance while maintaining a rich, full-bodied drape. At 22 oz per linear yard and an exceptionally wide 64″ width, the Encore provides outstanding coverage and reduces the number of seams required across large stage openings. Acoustically, it achieves a top-tier Noise Reduction Coefficient (NRC) of 1.00 and a Sound Absorption Average (SAA) of 0.99 when hung with 100% fullness via box pleats β making it one of the highest-performing acoustic drapery fabrics available. The fabric contains no known hazardous components and poses no inhalation or ingestion health risks under normal use, though prolonged skin contact may cause mild irritation. Its IFR flame resistance is inherent to the fiber β permanent, chemical-free, and guaranteed never to wash out. Certified to NFPA 701-2010 TM #1, California Title 19, Canada ULC S-109, British BS 5867: Part 2:1980, German DIN 4102 B1, IMO a.471 (XII)βA.563 (14) for cruise ships, and ASTM E-84 Class I/A, and approved by the California State Fire Marshall (CSFM Approval No. F-521.01), the Encore meets the most comprehensive set of international fire safety standards of any fabric in the Rose Brand IFR lineup.
