(And Why U.S.-Certified Fabrics Don’t Always Work Here)
When purchasing stage curtains, event drapery, or decorative fabrics for commercial spaces, many buyers assume that if a fabric is labeled “fire-rated”, it will automatically pass inspection.
Unfortunately, that assumption can be expensive.
Across Canada, theatres, schools, hotels, churches, and event venues regularly encounter situations where cheap imported curtains fail fire inspection — even though the supplier claimed the fabric was fire-rated.
One of the biggest reasons for this is simple:
Canadian fire codes are different from U.S. fire codes.
If the fabric isn’t specified properly, the material may be completely unusable in Canada.
Most fire-rated fabrics in the United States are tested under:
NFPA 701
However, in Canada the commonly referenced textile fire standard is:
These two tests measure flame resistance in slightly different ways and are issued by different governing bodies.
For example:
| Standard | Country | Governing Body |
|---|---|---|
| NFPA 701 | United States | National Fire Protection Association |
| CAN/ULC-S109 | Canada | Underwriters Laboratories of Canada |
Although they are similar, they are not identical tests, and certification must come from an approved laboratory.
In Canada, many venues and inspectors require proof that fabrics meet CAN/ULC-S109, especially for:
theatres
hotels
public assembly spaces
film and television sets
schools and universities
Without the correct documentation, the installation may be rejected.
Many inexpensive curtains sold online are only tested to NFPA 701, which is the American fire test.
While this is acceptable for U.S. installations, Canadian projects often require proof that the fabric meets CAN/ULC-S109 standards.
If the curtain supplier cannot provide Canadian certification, the fire inspector may not accept the material.
That means the entire installation may need to be replaced.
Another common issue is missing documentation.
When inspectors review a project, they typically request:
Flame test certificate
Test standard (NFPA or CAN/ULC)
Testing laboratory
Fabric identification
Without this documentation, the curtain may not be approved for use.
Many low-cost suppliers simply state:
“Fire resistant fabric”
But that description alone does not prove compliance with recognized fire tests.
Canadian building and fire codes often require fabrics to be certified to CAN/ULC-S109 or NFPA 701, and proof must be provided upon request.
Some fabrics are not inherently flame resistant.
Instead, they are treated with flame-retardant chemicals.
Over time, these treatments may degrade through:
washing
humidity
environmental exposure
improper cleaning
Fire authorities recognize this issue, and some standards require fabrics to be re-tested or re-treated periodically to maintain compliance.
This is why many theatres prefer IFR fabrics (Inherently Flame Resistant) instead of chemically treated materials.
Another risk with low-cost curtains is unverified testing claims.
Some imported fabrics are advertised as fire resistant but lack:
recognized laboratory testing
batch traceability
certification documents
If a fire inspector requests proof and the supplier cannot provide it, the installation may be rejected.
For large venues, this can delay productions, events, or building occupancy approvals.
Failing fire inspection can create serious financial consequences.
Possible outcomes include:
removing and replacing installed curtains
delaying theatre productions or events
re-ordering compliant materials
paying additional installation labour
failing a building inspection
In many cases, the cheapest curtain option becomes the most expensive mistake.
Before ordering fire-rated drapery, always confirm the following:
✔ Ask which standard the fabric meets
✔ Request the official flame test certificate
✔ Confirm whether the test is NFPA 701 or CAN/ULC-S109
✔ Verify the testing laboratory
✔ Ensure the certificate matches the exact fabric
These steps help ensure the material will pass inspection.
For Canadian installations, it is always safest to specify fabrics tested to CAN/ULC-S109 or both Canadian and U.S. standards.
At Equus Fabrics, we supply flame-rated textiles designed for commercial use in theatres, hospitality, and institutional projects across Canada.
Our fabrics include documentation suitable for inspectors and building approvals.
Fire-rated curtains are not just a design decision — they are a life-safety requirement.
Because Canada uses its own certification system for flame-resistant fabrics, relying on the wrong specification can result in failed inspections and costly replacements.
Understanding the difference between U.S. and Canadian fire standards ensures your curtains are compliant, safe, and ready for approval.
