Building looking for slope (from top to bottom) : Protective layer coating of SBS coiled material waterproof layer, a polyurethane waterproof coating film, 2 mm thickness, base treating agent, 30 mm or 40 mm, extrusion molding polyphenyl(EPS) board 20 mm, cement mortar, cement perlite thermal insulation mortar, the thinnest part is 50 mm, cast-in-place floor.
If you have already taken the composite board as interior wall, you don't have to do the final construction, because the inside and outside layer of composite board have been very smooth and no defects, if you want to do surface construction, there will demand many materials, because there is no surface composite board, but only those with grooves on the market, and the groove itself is for increasing the weight and pressure bearing strength of composite board. Supplement: Glass wool composite board is metal surface fireproof?panel, it's mainly made of rock wool and glass wool, it takes high quality coating steel plate as the plane material, continuous cotton fiber, rock wool and glass wool as the core material, high-density hard foamed polyurethane as the tongue-and-groove filling, shaped after high pressure foaming solidified, automatic solid cotton cloth and controlled by the ultra-long precision double track.
