Theaters, performing arts centers, and schools rely on flame-retardant fabrics for their masking curtains, main drapes, and borders. But when it comes to balancing safety, durability, and professional appearance, IFR velour stands out as the most trusted material.
Used for decades in stage design, inherently flame-retardant velour is designed to block light, absorb sound, and meet strict fire codes like NFPA 701. But not all velour is created equal.
This guide explores why Liba’s IFR Velour Stage Curtain Fabric is trusted by production teams, architects, and specifiers across the country — and why it’s an ideal match for masking curtains, grand drapes, and everything in between.
What Is IFR Velour Fabric?
IFR (Inherently Flame Retardant) velour is a plush, matte-finish polyester fabric where flame resistance is built into the fiber itself. Unlike FR-treated fabrics that lose fire resistance over time or with washing, IFR fabrics remain compliant for the life of the product.
Liba’s IFR Velour is available in three professional-grade weights - all NFPA 701 compliant and in stock for fast delivery.
- 10oz IFR Velour - Lightweight for skirting, pipe and drape, valances
- 15oz IFR Velour - Best suited for masking curtains, borders, legs, and backdrops
- 23oz IFR Velour - Heavyweight velour for main drapes, proscenium curtains, and sound absorption
Why Theaters and Performing Arts Centers Choose IFR Velour for Masking and Stage Curtains
1. Fire Code Compliant
Liba’s IFR velour meets NFPA 701, the standard fire code required for stage curtain fabrics in public and commercial venues. Whether you're outfitting a school auditorium or a professional theater, this compliance ensures safe, code-approved installations.
2. Excellent Opacity for Light Control
Velour is known for its light-blocking properties - a must for masking curtains, borders, and back-of-stage drapes. Liba’s 15oz and 23oz IFR Velour weights offer excellent opacity, helping eliminate backstage distractions and improving audience focus.
3. Durable and Easy to Maintain
Liba’s IFR velour is made from high-strength polyester, engineered for high tear resistance. It also features a low nap surface that makes it easy to spot clean - fits teams that need their curtains to look great performance after performance.
4. Fast Shipping Keeps Projects Moving
Unlike many mills with 8–12 week lead times, Liba keeps its IFR Velour fabrics in stock and ready to ship. Orders typically ship the same or next day - helping keep projects on schedule.
