EPS Cement Sandwich Panel is a prefabricated lightweight wall material designed specifically for fast and reliable partition wall construction in all types of buildings. The whole installation process of EPS Cement Sandwich Panel partition wall starts from accurate measurement and layout marking on the floor ceiling and two side vertical walls to confirm every panel position. Workers will first place the special U shaped fixed keel on the marked floor position then insert the EPS Cement Sandwich Panel into the keel and adjust it to keep completely vertical. After adjusting the panel position workers will fix the top of EPS Cement Sandwich Panel to the ceiling structure with special connecting parts then fill the gaps between panels with professional matching caulking mortar. The whole installation process of EPS Cement Sandwich Panel partition wall does not need a large amount of wet mortar operation which keeps the construction site clean and greatly reduces the waste of building materials. A skilled two person installation team can usually finish more than 20 square meters of EPS Cement Sandwich Panel partition wall in one working day which is several times faster than traditional brick wall building speed.
