Paper gypsum board is B1 grade fireproof material, why installed in the light steel keel can be treated in accordance with A-class fireproof material?
Partition wall is to have mineral wool, the ceiling does not seem to need it.
There are many kinds of gypsum board, there are fire gypsum board, fire gypsum board there are hierarchical, A grade that is gypsum board
Gypsum board installed on the light steel keel is not the focus, the focus is that it will fill in the light steel keel full of fire rock wool, a fireproof material. If there is no fire rock wool, paper gypsum board will be ordinary gypsum board. Also fail to meet the A-level fire protection requirements.
The fire grade has a description of the fireboard gypsum board for the B1 grade. But the paper gypsum board and light steel keel with the use. It will reach A-level fire. I would like to know whether there is a description of the national standard with the level B1 and light steel keel mix can reach A-level fire. I would like to use woodworking board as a base and light steel keel as a mixture of materials to achieve Class A fire. Whether the State has formal provisions to do so. Or only clearly stipulated that only gypsum board can be used as a mixed material with light steel keel labeled A level. Other materials are not allowed.
