I’ve been asked if Turbotorch is fire rated? Either AA, AB or AC.. Can you please advise me and maybe supply some written evidence.

IKO products that are tested for external fire performance are done so under the euro classification EN 13501. IKO Turbotorch Capsheet has not been tested and resultantly achieves a rating of F_ROOF^(T4). Our widely available torch on product that has been tested achieving a B_ROOF^(T4) is the IKO Protorch Capsheet. Here are the links to the Turbo Torch data sheets  and the ProTorch data sheet.
