Does Any One Know If A Fibreglass Roof From A Lorry Is Fire Proof?

[enfable]

I am not sure whether to place this here or motors so have done both.

I would like to know if anyone knows the fire rating on a fibreglass roof from a lorry?

I have found this online http://www.suigeneris.co.uk/fibreglass_grating/grp_grating_fire_resistant_finishes.html

but am unsure what type of fibreglass would be on a lorry roof

Thanks in advance

Probably as fireproof as boats made of fibreglass.
