Product Overview
Flame Retardant Poly-cotton Canvas is a safety-compliant substrate engineered for use in environments with specific fire code regulations. The base material is typically a poly-cotton blend, which is then treated with proprietary flame-retardant chemicals during the manufacturing process. This treatment imbues the fabric with self-extinguishing properties, reducing the spread of flame and limiting smoke generation.
This canvas is developed to meet or exceed international fire safety standards such as NFPA 701, BS 5867, and EN 13501-1. It maintains the printability and handling characteristics of standard coated canvases while adding a critical layer of safety. It is a necessary material for installations in public venues, transportation hubs, and commercial buildings.
Base Fabric
Poly-cotton Blend (e.g., 65/35)
Key Feature
Flame Retardant Treatment

Product Benefits
This specialized canvas provides essential benefits for safety-conscious projects without sacrificing core functionality.
Enhanced Fire Safety
Contributes to building safety by meeting code requirements for flame spread and smoke generation in public assemblies.
Regulatory Compliance
Facilitates approval processes for installations in venues such as theaters, museums, schools, and airports by providing compliant material.
Maintained Print Quality
The FR treatment is engineered to be compatible with digital printing, allowing for good color reproduction and image clarity.
Product Features
The material is designed with specific features to fulfill its dual role as a printable substrate and a safety material.
- Permanent FR Treatment: The flame-retardant chemicals are integrated into the fibers and coating, designed not to wash out or degrade under normal conditions.
- Self-Extinguishing: When the ignition source is removed, the material will cease to burn, limiting fire damage.
- Low Smoke Emission: Formulated to minimize the amount of smoke produced during combustion, improving visibility for evacuation.
- Texture Retention: Maintains the woven, textured appearance of poly-cotton canvas, suitable for aesthetic applications.
- Durable Coating: The surface coating accepts ink while protecting the FR treatment, ensuring performance over the life of the installation.
- Code Documentation: Can be supplied with manufacturer's certification or test reports to support project specifications.
Product Applications
Its primary use is in public and commercial spaces where fire codes dictate material specifications.
Performing Arts & Entertainment Venues
Used for stage backdrops, scenic elements, acoustic panels, and decorative wall coverings in theaters, concert halls, and studios.
- Theatrical Backdrops: Painted or printed scenery that must meet strict fire safety regulations for public performances.
- Acoustic Baffles: Sound-absorbing panels wrapped in FR canvas for both function and aesthetics.
Public Institutions & Education
Ideal for museums, libraries, schools, and government buildings where large-format graphics are installed in corridors and common areas.
- Museum Exhibition Graphics: Wall-sized interpretive graphics and backdrop prints within exhibition spaces.
- School Murals & Decor: Motivational graphics and artwork in hallways, cafeterias, and gymnasiums.

Application & Compliance Overview
| Application Setting | Typical Code Reference | Installation Consideration | Maintenance |
|---|---|---|---|
| Theaters/Auditoriums | NFPA 101, Local Building Code | Often used unframed or stretched; may require fire-rated hardware | Dust with soft brush; avoid wet cleaning unless specified |
| Museums & Galleries | Insurance Requirements, IBC | Integration with other fire-rated building materials | Professional conservator advice recommended for valuable art |
| Public Atriums | International Building Code (IBC) | Large scale requires engineering for mounting and tensioning | Periodic inspection for dust accumulation |
Specification and Installation Guidance
Certification Verification
Always request and retain the current flame test certification report from the manufacturer or supplier for your project records and inspections.
Pre-Print Testing
Conduct a small print and adhesion test with your specific ink and printer settings, as FR treatments can sometimes affect ink bonding.
Compatible Materials
Use flame-retardant or inherently non-combustible mounting substrates, adhesives, and framing materials to maintain the overall assembly's fire rating.
Storage and Handling
Store rolls in a dry environment. The FR treatment is durable, but prolonged exposure to moisture or direct sunlight before printing should be avoided.
Frequently Asked Questions
Frequently asked questions regarding Flame Retardant Poly-cotton Canvas.
Does the flame retardant treatment affect color reproduction?
The treatment may cause a slight off-white or cream base color compared to bright white canvases. This can subtly affect color gamut, particularly in blues and whites. Printer profiling is recommended for critical color work.
Is the treatment permanent?
Yes, our specified product uses a durable, non-leachable treatment designed to last the lifetime of the material under normal indoor conditions. It should not be dry-cleaned or subjected to harsh washing.
Can I apply a laminate over it?
Yes, but it is crucial to use a laminate that is also flame-retardant or that has been tested in combination with the canvas to ensure the entire laminate-substrate assembly still meets the required fire standards.
How do I prove compliance for an inspection?
The material supplier should provide a test report from an accredited laboratory (e.g., UL, SGS) stating the specific standards met (like NFPA 701). This report is your primary documentation.
Is it suitable for exterior use?
No. The flame-retardant treatment and the poly-cotton base are not designed for prolonged outdoor exposure to UV and weather. It is an interior product.
