Every large construction project needs a set of temporary site offices, meeting rooms, and welfare facilities for site managers, engineers, and workers, and the EPS Cement Sandwich Panel has become the standard material for building these temporary structures across the industry. The prefabricated panels can be assembled into full site office units extremely quickly, so the construction management team can move onto the site and start working almost immediately, without waiting weeks for traditional on site building work to finish. The good thermal insulation performance of the EPS Cement Sandwich Panel keeps the temporary offices at a comfortable working temperature, reducing the amount of energy needed for portable heaters and air conditioners on site. Unlike cheap thin metal site cabins that get extremely hot in summer and freezing cold in winter, the panel based site offices create a much more pleasant working environment for everyone on the construction team. When the project is finally completed, all the panels can be easily disassembled and transported to the next new construction site, to be reused again to build a brand new set of site offices. This reusability drastically cuts the total cost of temporary site accommodation over the full lifespan of a construction company, making the EPS Cement Sandwich Panel an extremely smart long term investment.
