how long is a fire dorr rated for?
For domestic the recommendation is FD30 ie 30 minute rating.
Having been told by the installer of my wood burner, that the plasterboard behind it needed to be the fire-proof variety ie red in colour, very dense/heavy, extremely expensive, I duly installed it. When I went to the manufacturers site for more data, it has the same 30 minute rating as ordinary plasterboard.
