Colour Range - Warranty
Expanded Polystyrene Fire-Retardant Grade (EPS-FR) is a 
thermoplastic that when exposed to high levels of sustained 
heat is subject to changes in its structural properties. On 
extremely hot days with no cooling wind, dark colours have 
been recorded as reaching extreme temperatures. The 
manufacturer of the steel recommends the following colours, 
subject to conditions of use, will maintain a temperature 
under 78.0ºC dry heat (see clause 9, sub-clause j of our 
product Warranty). Please refer to Clause 12 of the Warranty 
– Roof Products for full details.
•  Off White / Surfmist ®              •  Hamptons White
•  Gull Grey / Shale Grey ™        •  Zinc
•  Merino / Paperbark ®              •  Birch / Dune ®
•  Mist Green / Paperbark ®        •  Armour Grey / Windspray 
•  Smooth Cream / Classic Cream ™
To maintain Warranty cover with dark colours it is therefore 
recommended that a Thermosetting Phenolic Composite 
(TPC) or Mineral Wool (MW) core be used for all colours not 
listed above.
