Our GRP Fire Retardant profiles are to Fire Retardant BS476 : part 7 : 1997 Class 2 specification. They have an E modulus of E23 if they are over 5mm thick and they are also NON Halogenated. Therefore they will not omit toxic fumes if they do catch fire. These are generally used in areas where there is a high risk if a fire should establish itself.
