The Government has issued an Advice Note for building owners,
their professional advisers, and fire and rescue services,
regarding spandrel panels/window panels/infill panels on external
walls.
Although written for those responsible for the safety of
residents of high-rise (over 18 metres) residential blocks of
flats, the principles of this guidance may, in certain
circumstances, be applied to other premises.
The Advice Note makes it clear that building owners should check
materials used in spandrel panels (including window panels and
infill panels) to ensure they do not present a risk of fire
spread.
The Advice Note goes on to recommend that for buildings over 18
metres, the clearest way to ensure such panels do not present a
risk of fire is to confirm that the materials used are of "limited
combustibility", or better and where they do not meet this
classification to remove and replace them.
