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 unmodified polyethylene filler (category 3 in screening tests)
  • stone wool insulation.

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