Our polycotton glawningLITES are fitted with a fire-retardant stove jack and the rest of the tent is not fire retardant.Our cotton canvas glawnings are all fire retardant and have been treated with PROBAN prior to manufacture. Pre-treating the canvas before manufacturing the tent ensures that the PROBAN  polymer is embedded into the body of the canvas fibres so the treatment can last the life of the tent.  Adding Proban during the initial weaving process means that the fireproofing treatment will not degrade over time. It won't wash off with rain or wear out with UV.  Our glawnings have always complied to the British Standards Institution BS7837 'cigarette test'. BS 7837:1996 is the specification used to gauge the flammability performance of textiles that are used in the construction of marquees and similar textile structures. More recently our tents have also been certified with CPAI-84, the more rigorous Canvas Products Association International version of the ISO6941.
