The CAN/ULC-S109 standard governs the fire resistance of fabrics used in commercial and institutional buildings across Canada. In the hospitality and public sectors, it directly influences the selection of curtains and window treatments.
With its expertise in commercial textile design and manufacturing, Textiles Patlin supports establishments across Canada in creating custom curtains that meet the strictest fire safety requirements.
In this article, learn more about the CAN/ULC-S109 standard and why it matters when choosing compliant curtains.

What Is the CAN/ULC-S109 Standard?
CAN/ULC-S109 is a Canadian standard that defines the testing methods used to evaluate the fire resistance of fabrics and flexible materials. It is published by the Underwriters Laboratories of Canada and integrated into the National Building Code of Canada.
It is primarily used to determine whether a textile can be safely used in environments where fire propagation must be controlled, such as hotels, hospitals, and public spaces.
How Does the CAN/ULC-S109 Test Work and What Does It Measure?
The CAN/ULC-S109 test simulates a fabric’s exposure to two distinct flame conditions.
- The first involves a small ignition source, representing a minor fire incident such as a low-intensity open flame.
- The second reproduces exposure to a more intense flame in order to evaluate the material’s behavior in a more advanced fire scenario.
The evaluation goes beyond simply determining whether the fabric ignites. It also analyzes burn rate, the extent of material damage, and residue behavior after exposure. These factors help assess how the material performs under real fire-risk conditions.
To be considered compliant, a fabric must meet the requirements established for both levels of testing. This ensures consistent material performance when exposed to both low-level and more intense flame conditions, which is essential in commercial and institutional environments where fire safety is critical.
Types of Fabrics Concerned
A wide variety of textiles can be tested according to the CAN/ULC-S109 standard. This flexibility is important because compliance depends not only on the fiber type, but also on the treatment applied and the fabric’s performance once transformed into a finished product.
These categories include:
- Synthetic fibers such as polyester, often used for their stability and consistent performance
- Natural fibers such as cotton and linen, which generally require flame-retardant treatment to meet the standard’s requirements
- More complex decorative fabrics such as velvet or silk, commonly used in high-end hospitality environments
CAN/ULC-S109 vs NFPA 701
Although the NFPA 701 standard is used in the United States, it does not replace the Canadian CAN/ULC-S109 standard. Both standards evaluate textile fire resistance, but their testing methods differ.
The Canadian standard is generally considered more rigorous, particularly because it requires testing conditions that more closely reflect real curtain installations, including folded configurations.
Flame-Retardant Curtains: What Canadian Regulations Say
In commercial and institutional environments, curtains are not simply decorative elements. They are textile materials that can influence fire propagation, particularly because of their vertical installation and exposed surface area within interior spaces.
This is where the term “flame-retardant curtains” becomes commonly used. While it is a general designation, it typically refers to curtains manufactured with fabrics that have been tested to meet specific fire-resistance requirements.
In Canada, this performance is mainly governed by the CAN/ULC-S109 standard for vertically installed textiles. When an establishment looks for flame-retardant curtains, it generally refers to products whose fabrics have been validated according to this standard.
These requirements are intended to limit flame spread, improve evacuation conditions, and reduce risks associated with textile materials in public spaces.
Industries Concerned
The CAN/ULC-S109 standard is now widely used in sectors where fire safety is a major concern.
In hotels and resorts, it applies notably to curtains installed in guest rooms, corridors, and common areas.
Senior living residences, healthcare facilities, and hospitals must also comply with these requirements because of occupant vulnerability and more complex evacuation procedures.
Theaters, performance venues, and cultural centers are another important example, since textiles play a central role in stage curtains, scenery, and backstage areas.
The standard is also found in many schools, universities, meeting rooms, and convention centers throughout Canada.
Where to Find CAN/ULC-S109 Curtains in Canada
Choosing curtains compliant with the CAN/ULC-S109 standard involves more than simply selecting a flame-retardant fabric.
In commercial, institutional, and hospitality projects, compliance also depends on manufacturing quality, material stability, and the textile supplier’s ability to document the actual performance of the installed product.
A specialized supplier should be able to provide valid certifications, accredited laboratory test reports, and clear documentation regarding the materials used. This step is especially important in projects subject to inspections, insurance requirements, or specific construction standards.
The Importance of Choosing a Reliable Partner
The risks associated with using non-compliant curtains can be significant. In some cases, unsuitable products may lead to failed inspections, project delays, or costly corrections after installation. For hotels and public buildings, the stakes also involve management liability and occupant safety.
This is why many establishments across Canada choose to work with specialized companies capable of supporting the project from curtain fabric selection all the way to final installation.

FAQ About the CAN/ULC-S109 Standard
CAN/ULC-S109 certification confirms that a fabric has been tested according to a Canadian fire-resistance protocol. It ensures that the material meets the safety criteria required in commercial and public buildings.
In many commercial and institutional buildings, yes. Hotels, schools, and hospitals generally need to use compliant textiles in order to meet building code requirements and local authority regulations.
NFPA 701 is an American standard, while CAN/ULC-S109 is Canadian. Although both measure fire resistance, the Canadian standard is generally stricter and better suited to local regulatory requirements.
It helps reduce the risk of fire spread in occupied spaces, improves evacuation time, and ensures regulatory compliance for hospitality establishments.
