9.5mm Standard Plaster Board

Our fire resistant concealed ceiling gypsum board is a safety-first building ceiling material, certified with Euro-class A1 non-combustible grade, the highest fire safety standard for interior building materials. Different from ordinary ceiling boards, its gypsum core contains abundant chemically bound crystalline water. In case of fire, the internal water molecules evaporate rapidly to form a dense steam barrier, which effectively isolates high temperature, absorbs heat energy and delays flame spread, providing precious escape time for personnel and protecting building structural safety.

Adopting a fully concealed installation structure, this fireproof gypsum board hides all installation keels and connectors, maintaining a neat and integrated ceiling appearance while achieving excellent fire protection performance. It does not release toxic smoke or harmful substances when exposed to high temperature, fully complying with international environmental protection and fire safety specifications, and is the preferred ceiling material for public buildings and high-safety requirement spaces.

Gypsum Board is the technical product name used by manufacturers for a specific board with a gypsum core and a paper facing and can be described as follows: Regular Gypsum Board, Fire Resistant Gypsum Board, Moisture Resistant Gypsum Board and Water Resistant Gypsum Board.
