    Jack Smith's comment 21 June, 2017 3:38 pm

    Thermal pannels Celotex FR5000 seem to have similar UK fire specifications than Reynobond PE, except in part 6*

    Reynobond PE:
    Fire propagation BS 476, part 6: class 0
    Surface spread of flame BS 476, part 7: class 1

    Celotex FR5000:
    Fire propagation BS 476, Part 6: Pass (*)
    Surface spread of flame BS 476, Part 7: Class 1

    *No class?? What does it mean?
    Has been considered the reaction and contribution to fire spread of that material?


    Good info, but I miss comparative reference to EU regulations before to Middle East, since UK is in Europe, even I assume UK did not join EU standards.

    About chimney effect of air camber, an suggestion: it can be blocked in fire case if intumescent coat is put in one internal face, even in horitzontal bands.
