Porcelain pavers supported by regular polypropylene pedestal supports will normally meet the requirements of ASTM Test Method E108-11 “Standard Method of Fire Tests of Roof Coverings”. This tests roofing products for spread of flame and the ability of the roof covering or roofing system to resist fire penetration from the exterior to the underside of the roof material when exposed to flames.
However, in some densely populated urban regions, more severe requirements or regulations may apply, requiring pedestals to possess fire resistant properties.
Until recently, the only pedestals we have been able to offer with some fire resistant properties are the Eterno VO series pedestals. These pedestals are produced with special compounds that prevent the spread of flames due to their self-extinguishing properties and also produce significantly less smoke fumes than other plastic pedestal supports.
However, we can now offer a range of steel pedestals that are totally non-combustible. The Archatrak IGNO range of pedestals are completely height adjustable and provide incremental height adjustment from as low as 1″ to a maximum of 20″. See further details here.
Eterno VO self-extinguishing pedestals are available in both the SE range with self-leveling head and the fixed head NM ‘Maxi’ range with wider body and tapered twist rings for slope adjustment.
Note that VO pedestals are only available on special order with a lead time of min. 8 weeks.
