Question to the Department for Levelling Up, Housing & Communities:

To ask the Secretary of State for Housing, Communities and Local Government, whether the use of aluminium composite materials with a polyethylene core is suitable for cladding on high-rise tower blocks under Approved Document B.

The Government’s view is that aluminium composite material cladding with a polyethylene core would not be in accordance with the Building Regulations 2010, Schedule 1 requirement B4(1), or the requirements in Building Regulations guidance, set out in paragraph 12.7 of Volume 2 of Approved Document B, that insulation products and filler material used in external wall construction should be of limited combustibility for buildings over 18 metres in height.
