Fire Rating

All Palisade panels have a ‘Class B’ FSI fire rating per ASTM E84.

Significance and Use

  • 4.1 This test method is intended to provide only comparative measurements of surface flame spread and smoke density measurements with that of select grade red oak and fiber-cement board surfaces under the specific fire exposure conditions described herein.
  • 4.2 This test method exposes a nominal 24-ft (7.32-m) long by 20-in. (508-mm) wide specimen to a controlled air flow and flaming fire exposure adjusted to spread the flame along the entire length of the select grade red oak specimen in 51/2 min.
  • 4.3 This test method does not provide for the following:
  • 4.3.1 Measurement of heat transmission through the tested surface.
  • 4.3.2 The effect of aggravated flame spread behavior of an assembly resulting from the proximity of combustible walls.
  • 4.3.3 Classifying or defining a material as noncombustible, by means of a flame spread index by itself.

1. Scope

  • 1.1 This fire-test response is standard for the comparative surface burning behavior of building materials is applicable to exposed surfaces such as walls. The test is conducted with the specimen in the ceiling position with the surface to be evaluated exposed face down to the ignition source. The material, product, or assembly shall be capable of being mounted in the test position during the test. Thus, the specimen shall either be self-supporting by its own structural quality, held in place by added supports along the test surface, or secured from the back side.
  • 1.2 The purpose of this test method is to determine the relative burning behavior of the material by observing the flame spread along the specimen. Flame spread and smoke developed index are reported. However, there is not necessarily a relationship between these two measurements.
  • 1.3 The use of supporting materials on the underside of the test specimen has the ability to lower the flame spread index from those which might be obtained if the specimen could be tested without such support. These test results do not necessarily relate to indices obtained by testing materials without such support.
  • 1.4 Testing of materials that melt, drip or delaminate to such a degree that the continuity of the flame front is destroyed, results in low flame spread indices that do not relate directly to indices obtained by testing materials that remain in place.
  • 1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
  • 1.6 The text of this standard references notes and footnotes that provide explanatory information. These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of the standard.
  • 1.7 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire-hazard or fire-risk assessment of the materials, products, or assemblies under actual fire conditions.
  • 1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
  • 1.9 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.


Palisade panels are waterproof. Our panels are guaranteed not to water-stain, bow, swell or rot. They are ideal for use in moist and humid environments like basements.

Mold & Mildew Resistant

Palisade panels are constructed from materials that inhibit mold and mildew. This means our panels can be installed in a variety of environments where moisture is a concern. They are manufactured from PVC with a smooth or decorative, embossed surface texture. PVC panels solve the problems of water damage and mold or mildew that are traditionally experienced with fiber-based lay-in panels.

  • No water stains, no moisture-related sagging, no rot
  • Mold and mildew resistant
  • Nonporous, nonabsorbent
  • Hygienic, easy to clean, easy to disinfect

A shortlist of the benefits of PVC

  • PVC is a safe and trusted product: PVC is used for blood bags, plastic tubing for surgery, medicine security bags and many other applications in the medical sector. It is also used in electrical cables, hygienic food packaging, safe and sustainable toys, plastic water bottles, etc.
  • PVC is easy to convert: PVC can easily be converted into many different forms, making it an ideal product for wall, façade cladding, etc.
  • PVC consumes fewer fossil fuels than other basic plastics. PVC consists of 57% salt, a material that is sufficiently available in nature.
  • PVC is a relatively inexpensive construction product. That is why PVC is used for windows, wall cladding, doors, pipes and many other applications in the construction industry.
