CAN/ULC-S109 FR Duvetyne

🔥 Understanding CAN/ULC-S109 FR Standards for Duvetyne — What Every Designer, Fabricator & Buyer Should Know

When it comes to stage and event fabrics, “fire-retardant” isn’t a feature — it’s a requirement.
Whether you’re dressing a theatre, building a film set, or installing curtains in a hotel ballroom, your fabric has to meet Canadian fire safety standards.

At Equus Fabrics, we take this seriously.
Our IFR Duvetyne, Velour, and Fire Velvet lines are all tested to CAN/ULC-S109, the gold standard for fire-retardant (FR) textiles in Canada.

But what does that code actually mean?
Let’s break it down so you can specify and buy fabrics with confidence.

🇨🇦 What Is CAN/ULC-S109?

CAN/ULC-S109 is the Canadian national test method for determining the flame resistance of textile fabrics used in public buildings.
It’s the Canadian equivalent of NFPA 701 (U.S.), but with stricter parameters in some areas.

The test measures:

• How a fabric reacts to open flame

• Whether it continues to burn or self-extinguishes

• Whether it produces flaming debris or drips

• And how far the flame travels up the sample

Only fabrics that self-extinguish within a few seconds and do not ignite or drip flaming particles can pass and be legally used in most commercial interiors, theatres, and hospitality settings across Canada.

🧵 IFR vs. FR vs. NFR — Know the Difference

In the fabric industry, these terms get mixed up constantly. Here’s what they actually mean:

Our Equus IFR Duvetyne is woven from 100% IFR polyester, meaning it stays compliant for the life of the fabric — not just the first show or installation.

🎭 Why Duvetyne Is the Industry Standard

For over a century, black duvetyne has been the unsung hero of film, theatre, and stagecraft.
Its matte brushed surface absorbs light instead of reflecting it, and its dense yet flexible weave makes it perfect for:

• Stage masking

• Backdrop drapery

• Temporary set walls

• Light-blocking and sound-softening panels

When made with IFR fibers, duvetyne delivers both the look professionals love and the code compliance inspectors demand.

⚙️ How the CAN/ULC-S109 Test Works

Here’s what the lab process typically looks like:

1. Sample Preparation – Fabric is cut into a controlled size and conditioned in a humidity chamber.

2. Vertical Flame Test – A standardized flame is applied for 12 seconds.

3. Observation – Technicians measure flame spread, after-flame, and after-glow times.

4. Pass Criteria –

   • Flame spread less than 8 inches

   • Self-extinguish within seconds

   • No flaming drips

Fabrics that meet these standards are certified as CAN/ULC-S109 compliant — safe for permanent or temporary public installations.

🏢 Where FR Fabric Compliance Matters

In Canada, fire inspectors and code enforcement officers often check for compliance in:

• Theatres, cinemas, and performance venues

• Hotels, restaurants, and conference spaces

• Schools and universities (stage and gym drapes)

• Film production sets and studios

• Convention centres and trade show installations

Failure to use certified FR fabrics can lead to fines, failed inspections, or forced removal of materials — a costly mistake that’s easily avoided by buying verified IFR fabrics.

🧠 Quick Tip for Buyers

If you’re purchasing for a commercial or public project, always ask your supplier for a current FR certificate that specifically lists CAN/ULC-S109.
If they can’t provide one, it’s not truly compliant.

At Equus, every roll of our IFR Duvetyne and FireVelvet comes with documentation for your records and peace of mind.
