What if the fire starts in the false ceiling?

[Oxo]

Then put one above

Thought most did that?

Depends on the size of the void

[Oxo]

True.

As it was not mentioned, I thus gave my opinion.

Also suprising how many times I have seen "additional works" and no fire foam used.

I only assume these installs are done to the correct category and thus not an issue. If its under 800 it doesn't need covered anyway as oxo has already pointed out.

Actually JW pointed out the size issue.

I just mentioned the fittment of them in a void.

What's fire foam?

[james.wilson]

Fire stop I assume?

It's basically fire resistant expanding foam. A college we do has recently gone mad with the stuff, must have cost them a fortune to do. We use the mastic.
