Fire Retardant Treatments
John Brash recommends a range of fire retardant treatments; the most typical
is Dricon fire retardant, approved by the NASC. Other suitable treatments include
Pyrolith and FirePro.
Fire retardant treatments should be specified to BS 476: Part 6&7: 1997 giving
either a Class 1 or a Class 0 rating. Alternatively this can be specified to
BS EN 13501-1 to either Euroclass B (transposes to Class 0) or Euroclass C (transposes
to Class 1).
