When you renovate parts of your existing corporate headquarters, you often need extra temporary office space to accommodate teams that would otherwise be displaced by construction work. The modular EPS Cement Sandwich Panel lets you build a full code-compliant temporary office zone inside your existing headquarters unused atrium or large meeting space, in less than one week. These temporary walls deliver full fire safety, sound insulation, and thermal comfort, so the teams working in the temporary space will have a normal comfortable working environment identical to their regular offices. After the renovation work finishes, you can completely disassemble the temporary panels and store them for future use, generating almost zero construction waste. This eliminates the huge cost of renting external temporary office space for hundreds of employees during your headquarters renovation project.
