B1 Fire Rated Shades – International Fire Safety Standard

B1 is the gold standard of flame retardancy under the German DIN 4102 classification system, recognizing materials that are “difficult to ignite” and self‑extinguishing. Our B1 Fire Rated Shades meet this rigorous international standard, providing verified fire safety for residential and commercial projects worldwide. Unlike topical treatments that can wash off or degrade, our B1‑rated fabrics are woven from inherently flame‑retardant polyester fibers—the FR properties are integrated into the polymer during extrusion. This permanent protection will never diminish, even after years of cleaning and sunlight exposure. B1 certification is widely recognized across Europe, Asia, and the Middle East, making these shades the preferred choice for international hotels, corporate offices, embassies, and luxury residences. Available in all our product categories: roller, roman, cellular, zebra, and sheer shades. Custom‑sized to your exact window dimensions, with cordless, continuous cord loop, or motorized operation. International safety, globally trusted.

What is B1 Fire Rating?

DIN 4102 is a German fire‑safety standard that classifies building materials based on their reaction to fire. B1 is the classification for “flammable building materials – difficult to ignite” (schwerentflammbar). To earn a B1 rating, materials must:

  • Self‑extinguish within a specified time once the ignition source is removed

  • Prevent flame spread beyond the tested area

  • Avoid producing excessive smoke or flaming droplets

B1 is the highest classification for non‑combustible building materials and is required for many commercial and public projects across Europe and internationally.

Inherently Flame‑Retardant Fibers

Our B1‑rated fabrics are woven from inherently flame‑retardant polyester, not treated with topical chemicals that can wash off or degrade. The FR additives are integrated into the polymer during fiber extrusion, ensuring:

  • Permanent protection — Will never wash out or wear away

  • No chemical migration — Additives remain locked inside the fiber

  • Consistent performance — Uniform protection across the entire fabric

  • Environmentally preferable — No hazardous reapplications or surface treatments

Available Across All Shade Styles

B1 Fire Rated fabrics are available across our standard polyester collections:

  • B1 Roller Shades — Smooth, textured, linen‑look; light‑filtering, room‑darkening, blackout

  • B1 Roman Shades — Flat, hobbled, relaxed; light‑filtering, room‑darkening, blackout

  • B1 Cellular Shades — Single‑cell and double‑cell; light‑filtering, room‑darkening, blackout

  • B1 Zebra Shades — 3" and 3.5" bands; light‑filtering, room‑darkening, blackout

  • B1 Sheer Shades — 2" and 2.5" vanes; light‑filtering, room‑darkening

Premium collections (Premier, B5) and specialty fabrics (linen blend, metallic) are not available in B1‑rated versions.

Ideal for International Projects

B1 certification is recognized—and often required—in:

  • Europe — Germany, France, UK, Italy, Spain, and EU member states

  • Middle East — UAE, Saudi Arabia, Qatar, where DIN standards are widely referenced

  • Asia — Singapore, Hong Kong, Japan; common in luxury hotels and offices

  • North America — While NFPA 701 is more common, B1 is accepted as an equivalent standard for many global brands

Certification Documentation

Every B1 Fire Rated shade order includes a certificate of compliance and, upon request, the official DIN 4102 B1 test report from an accredited laboratory. These documents are accepted by building inspectors, fire marshals, and project specifiers worldwide.
