When choosing a container house as an temporary office or dormitory, people will be concerned about sound insulation. In fact, this worry is unnecessary. Because each container house is a integrated structure, there is a complete roof structure and floor structure. The first and second floors of the container house belong to different containers. The floor material of each container is galvanized steel, MGO board or cement board, plus a layer of PVC floor leather. The sound insulation effect of this structure will be much better compare with other temporary house. And we are now upgrading the floor system, using more floor purlins and thicker MGO boards, so that the sound insulation effect will be better.
