FR Comshade® is a premium shadecloth, registered by the California State Fire Marshal

After two years of development, and having passed the rigid testing required by the California State Fire Marshal (per Title 19, Section 1237.1; Original State, after 72 hours Leaching and after 100 hours Weathering) as well as long-term accelerated weathering, Polyfab USA LLC is proud to announce that our newly re-developed FR Comshade will soon be available from Polyfab distributors across the Americas.

Next Generation FR Additive

The original FR Comshade® was developed by Polyfab Australia over 12 years ago, and was the first HDPE shadecloth to meet California State Fire Marshal requirements. After a long effort to redevelop the product with currently available ingredients, we were able to find a “new generation” FR additive that is environmentally safe and less aggressive against the UV inhibitors. Because of this, we are able to offer a 10-year Limited Warranty.

Heavy Duty Shadecloth is an Industrial Textile made from High Density Polyethylene, and combines Ultra Violet (UV) stabilisers and colour additives. During the manufacturing process imperfections may occur. These imperfections are cosmetic only, and will not impact or interfere with the performance of the life of the shade fabric or the function for which it has been designed.

The knitted Shade Sail, should be installed by a company or individual that has received accreditation by the Building Commission, or Building Association, or other recognised building authorities in your state. If unsure please check with your State Building Authorities and your local Council.

Your shade sail canopy should be installed firm and tight so as to reduce windflap in the shade fabric. Shade fabric that is loose and sloppy will cause premature failure due to mechanical breakdown. This is not UV breakdown and is not covered by the warranty. The shade sail will require periodic maintenance to ensure that the shadecloth fabric remains tight.

Your shadecloth canopy may become dirty over time. Care should be taken to avoid Chemicals that may contain Bleach, or other agricultural or industrial Chemicals containing Sulphur and or Halogens (chlorine Bromine). These Chemicals may attack the UV stabilisers within the Shadecloth, thus reducing the Life of the product and negating the warranty.

The following list of chemicals that may cause such interactions are only some examples and not exhaustive. Such chemicals may include: pesticides, metals, metal oxides and metal salts, all halogens and chemical compounds containing halogens or sulphur in all their oxidation states. Care should be taken to avoid exposure to petrol, oils etc.

When cleaning the shadecloth, we recommend the use of a mild dish washing liquid with the use of a low pressure water hose and a soft scrubbing brush. We do not recommend the use of high pressure water, to blast the fabric clean.

The fabric warranties do not pertain to such damage caused by storms, hailstorm, earthquake, mechanical damage done by birds or other animals, fire, lightening etc. Again this is not an exhaustive list and it is for reference only.

Please refer to our Product Warranty, for further information. If you remove the shade sail over winter, ensure that it is stored away from rats and mice, preferably stored in a protective bag.
