20oz Crescent Velour

At iStudio Projects, our Rose Brand 20 oz. Crescent Velour (SKU # VL200001–VL200017) is a premium Inherently Flame Resistant (IFR) performance fabric engineered for theatrical draperies, stage curtains, and acoustic panels in demanding performance environments. Woven from 100% IFR polyester with a napped construction, the Crescent Velour offers exceptional sound absorption — achieving a Noise Reduction Coefficient (NRC) of 0.95 and a Sound Absorption Average (SAA) of 0.96 when hung flat with 100% fullness — making it one of the highest-performing acoustic fabrics available for stage applications. At 20 oz per linear yard and 54″ wide, it provides a substantial, full-bodied drape with rich visual depth. Unlike chemically treated fabrics, the Crescent’s flame resistance is inherent to the fiber itself, meaning it will never wash out and remains permanently compliant for the life of the fabric. Certified to NFPA 701-2010, California Title 19, Canada ULC S-109, British BS 5867, IMO standards, and ASTM E-84 Class I/A, it is approved by the California State Fire Marshall (CSFM Approval No. F-599.01).

Product Description

Key Features

Heaviest IFR Velour in the Rose Brand Line — at 20 oz per linear yard (452 g/m²), it delivers the deepest, richest nap and most commanding stage presence of any polyester IFR velour in the range
Exceptional Acoustic Performance — independently certified NRC of 0.95 and SAA of 0.96 (NGC Testing Services, NVLAP-accredited, ASTM C 423-09a), the highest acoustic rating in the Rose Brand velour lineup
Inherently Flame Retardant (IFR) — flame resistance is built permanently into the polyester fiber; will never wash out for the life of the fabric
No Hazardous Components — OSHA-reviewed MSDS confirms no known hazardous ingredients, making it safe for standard theatrical handling environments
Broadest Flame Resistance Certification Suite in the Line — includes NFPA 701, CA Title 19, Canada ULC S-109, BS 5867, ASTM E-84 Class I/A, and IMO maritime certification for cruise ship applications
California State Fire Marshal Approved — CSFM Approval No. F-599.01
Special New York City Certificate — available upon request
Machine Washable — water washing does not affect IFR properties; tumble dry safe up to 140°F
Woven Napped Construction — deep pile provides superior light absorption on stage and maximum acoustic energy absorption in architectural applications
Extra-Long Roll Lengths — available in 90–110 yard rolls, reducing seam frequency in large-format drapery installations
No Ironing Required — permanent press polyester construction; wrinkles release naturally when hung

Operation Guidelines

Storage:

The preferred storage method is to leave draperies hanging in place. If removal is necessary, store in breathable canvas hampers or canvas storage bags — never in sealed plastic, which traps humidity and promotes mold.
Tape all metal components (grommets, ring lines) to prevent contact with the fabric during storage, as metal can corrode and stain FR fabric.

Folding:

Avoid folding whenever possible. If folding is unavoidable, never allow folded drapes to bear weight — including their own. Place a cardboard tube (as large a diameter as possible) at the fold point to protect the nap.
To store in a hamper: lay flat on its back, fold seam over seam in layers, then roll from bottom to top without heavy pressure. Do not stack heavy items on top of bagged drapes.
When rehung after storage, allow a few days before performances — residual wrinkles will hang out naturally.

Periodic Cleaning:

Dust at least once per year by shaking the drapes and sweeping with a dedicated soft-bristle broom. Clean the stage and lay protective plastic or paper on the floor before lowering drapes for sweeping.
Remove minor stains with warm water, K2R spot remover, or commercial dry-cleaning fluid. Always pretest on a small, low-visibility area first as stain removers may affect fabric color.

Major Cleaning:

For full cleaning, use a commercial dry cleaner. Allow drapes to air out for approximately one week in an unoccupied space after dry cleaning before exposing performers or audiences.
Machine or tub washing is permitted using synthetic detergents only. Do not use soap, bleach, or fabric softeners as these may compromise flame retardancy.
Tumble dry at up to 140°F — remove immediately and hang. Do not over-dry. No ironing required.

Flame Resistance Maintenance:

The IFR flame resistance is permanent and will not wash out. However, annual field testing using the NFPA 705 Field Test method is recommended, as accumulated airborne dust and oils may diminish surface flame resistance over time.
