Plastic sheeting is combustible — unlike gypsum board, steel, and fiberglass. Many customers confuse fire retardant with fire resistant products. Contractors frequently contact us requesting a material with a 1-hour fire rating. No plastic sheeting product currently meets that requirement. Understanding the difference between these terms saves time during inspection and reduces liability in the event of a fire.
At Americover, we specialize in fire-retardant plastic sheeting solutions including Heat Shrink Wrap, Anti-Static, String Reinforced, Black-Out, and Printed and Non-Printed polys. Common applications include ship renovations, temporary indoor dust containment, haunted houses, and insulation covering.
⚠️ Important distinction: “Fire-rated” and “fire retardant” are not the same thing. Traditional fire ratings (such as 1-hour or 2-hour ratings) apply to structural assemblies like walls, doors, and floors — not to plastic sheeting films. Plastic sheeting earns fire test certifications (such as NFPA 701 or ASTM E84) — not fire ratings. Always confirm which standard your project or inspector requires before specifying a product.
What Is Fire Retardant?
Many fabrics, films, and flexible materials used in public spaces, temporary enclosures, and construction applications may be required to meet flame retardant certification standards. In many cases, these requirements are based on standards adopted through local building or fire codes.
Fire-retardant materials are designed to slow ignition, reduce flame spread, or self-extinguish when exposed to an open flame. However, they are not necessarily noncombustible. Their performance depends on the material composition and the standard used to test them.
The most widely referenced standard in the United States for plastic films and similar materials is the NFPA 701 Standard: Methods of Fire Tests for Flame Propagation of Textiles and Films. This standard includes multiple test methods that evaluate:
| ✓ | Flame propagation under controlled exposure conditions. |
| ✓ | After-flame time and whether the material continues burning once the ignition source is removed. |
| ✓ | Char length and related indicators of flame spread performance. |
NFPA 701 is a pass/fail test. To earn certification, a material must meet specific performance criteria without excessive flame propagation.
Many jurisdictions adopt NFPA-based standards for public spaces, but requirements vary depending on local building and fire codes. Always confirm the applicable standard with your inspector or project specifications.
What Is Fire Resistant?
Fire-resistant or flame-resistant materials are designed to resist ignition and self-extinguish when exposed to flame. However, they are not necessarily noncombustible. Their level of performance depends on the material itself and the test standard used.
Many flame-resistant materials are engineered to reduce melting, dripping, and flame spread — but performance varies by formulation and test method.
Flame resistance is evaluated through different material-specific standards depending on the application. Textiles, plastics, and structural assemblies are not tested the same way, which is why it is important to match the material to the required standard in your project specifications.
For example, structural fire ratings such as 1-hour or 2-hour ratings apply to complete wall, floor, ceiling, or door assemblies. Flexible plastic sheeting products are typically evaluated using flame spread or flame propagation tests rather than assembly fire-resistance ratings.
Is Fire Retardant the Same as Flame Retardant?
In construction and plastic materials, the terms fire retardant and flame retardant are often used interchangeably. Both generally refer to materials designed to slow flame spread and reduce fire intensity. These terms do not mean the material is fireproof or noncombustible.

Common Fire Rating Tests for Plastic Sheeting
When contractors and inspectors reference “fire-rated” plastic sheeting, they typically mean sheeting that has passed one or more standardized fire tests. Here is a breakdown of the most common tests and what each one measures:
| Standard | Governing Body | What It Measures | Pass/Fail or Rated? |
|---|---|---|---|
| NFPA 701 | National Fire Protection Association | Flame propagation of textiles and films. Commonly referenced for plastic sheeting used in public spaces, temporary enclosures, and construction applications. | Pass / Fail |
| ASTM E84 | American Society for Testing and Materials | Surface burning characteristics including flame spread and smoke development. Materials may be classified as Class A, B, or C. | Class A / B / C Rating |
| ASTM D635 | American Society for Testing and Materials | Rate of burning of plastics in a horizontal position. Used to evaluate how quickly a plastic material burns when ignited. | Measured Result / Comparative Test |
| ASTM D1929 | American Society for Testing and Materials | Ignition properties of plastics, including the temperature at which a material will ignite under controlled conditions. | Reported Value |
| UL 94 | Underwriters Laboratories | Flammability characteristics of plastic materials. Rates materials as HB, V-0, V-1, or V-2 based on burn behavior and self-extinguishing performance. | HB / V-0 / V-1 / V-2 Rating |
💡 Which test applies to your project? NFPA 701 is commonly required for plastic sheeting used in temporary enclosures, construction sites, and public-facing spaces. ASTM E84 may apply when interior finish classifications such as Class A, B, or C appear in your project specs or code requirements. If you are unsure which standard your project requires, check your specifications or confirm with your inspector before ordering.
The Best Fire Retardant Plastic Sheeting from Americover

Fire Retardant Heat Shrink Wrap
What it is: Available in both fire-retardant and non-FR versions with UVI treatment. As a #4 LDPE product, it may be recyclable where appropriate recycling programs exist.
How it’s used: Enclosing scaffolding, covering buildings, bridges, and ships, and serving as a temporary roof cover, storage cover, transportation cover, or industrial containment barrier.
Fire Retardant String-Reinforced Plastic Sheeting
What it is: Two layers of fire-retardant low-density polyethylene with string reinforcement — ideal for construction applications that require both fire performance compliance and tear resistance.
