What kind of material is better in the room wall?
20 square, red brick about 20 * 130 = 3600. Red brick about 4 hair piece. I am not sure about cement and sand. Sand, then about 100 yuan side, about 20 yuan a bag of cement, rock and crystal 15 yuan or so a package. The above materials are not shipping. Workers are hard to say, two people two days package powder almost it. Cement sand can ask the workers. Not enough to make up again
Better cement board, but also waterproof. Insulation, noise can be added in the middle of the partition sound insulation, insulation materials. Cement board than gypsum board expensive it, about 30 yuan it, a long time did not buy, forget the. Sound insulation is also cheaper, but you use less, the price is relatively high. As well as iron plate sound transmission speed and the effect is certainly more obvious than the wall.
Indoor wall generally use light steel keel plus gypsum board to do, with 100 light steel keel made Lilong, 38 light steel keel to do heart, with sound insulation requirements of the middle of the space filled with sound insulation cotton. Walls on both sides of the gypsum board, such as the future need to hang heavy objects (air conditioning, murals, television, etc.) can first cover a layer of woodworking board, and then cover the gypsum board. The last patch, scraping, coated latex paint.
