Details

The government is undertaking large scale testing of cladding systems to understand better how 3 different types of Aluminium Composite Material (ACM) panels behave in combination with 2 different types of insulation in a fire.

This note sets out advice to building owners following the results of the large scale test for a wall system including:

  • ACM with a fire retardant polyethylene filler (category 2 in screening tests)
  • PIR foam insulation

This should be read alongside the government’s explanatory note on the large scale wall systems testing.
