+Environmental friendly +Non-combustible +High strength +Heat & sound insulation +Ten years exporting experience. Gypsum board is made from gypsum as the main materials, and adding some fiber, stickiness glue etc. It is fireproof, sound insulation, heat resistance, light weight, high intension, besides, it is easy to apply, which can be nailed, sawed, digged. The board is widely used for inner wall, ceiling, partition.1.TYPE :A: Standard boardB: Fire-resistant boardC: Water resistant board2.Gypsum board edge:A: tapered edge (recessed edge)B: square edge (straight edge)3.Color of the surface protective paper:A: White ------usually for standard boardB: Red ------usually for fire-resistant boardC: Light green------usually for moisture resistant boardD: Light blue ------ usually for moisture resistant boardE: Other colors upon your detailed request.4. function:The property of our products is: fire resistant, moisture resistant, sound insulation, heat preservation,etc5.
