Following the disastrous Grenfell Tower fire in London, United Kingdom authorities conducted fireproofing tests on seven combinations of cladding and insulation, revealing that over 200 high-rise residential buildings were at risk in the UK. Four of the seven types of building configurations failed. They were:

  • Aluminum composite material (ACM) panels with an unmodified polyethylene core and a rigid
    polyisocyanurate (polyiso) foam
  • ACM panels, unmodified polyethylene core, and stone wool insulation
  • ACM panels, fire-retardant polyethylene core, and polyiso foam insulation
  • ACM panels, fire-retardant polyethylene filler, and phenolic foam insulation

The three that passed were:

  • ACM panels, fire-retardant polyethylene core, and stone wool insulation
  • ACM panels, limited combustibility filler, and polyiso foam insulation
  • ACM panels, limited combustibility filler, and stone wool insulation

A final report on recommendations on high-rise residential buildings is expected to be released in the spring.
