The product used was Reynobond, which is available with different types of core material—polyethylene, as reportedly used in Grenfell Tower (Reynobond PE), or a more fire-resistant material (Reynobond FR). The Reynobond cladding reportedly cost £24 per square metre for the fireproof versions, and £22 for the flammable version. According to the BBC, the more fire-resistant version (Reynobond FR) is a very new product, and it is unclear whether it was available at the time the building was being clad.
