Hi all,

Is there a fireproof way to join fireboard? And do you have to do
something special at the edges where the fireboard butts up against the
plasterboarding?

I'm applying fireboarding to the underside of a staircase (naughty
developers....) and want to do it properly. Not much point putting
fireboard in place if the fire just finds the gaps.... It's not in a
place where anyone will see it (void between my bathroom ceiling and
the stairs to the floor above) so it doesn't have to be beautiful.
Initially thought scrim tape but its glass fibre and that burns like
crazy....
Any ideas?
Thanks in advance

Ben
