Large corporate headquarters buildings are subject to the strictest commercial fire safety regulations, designed to protect hundreds of employees, expensive company assets, and critical business data from fire risk. The EPS Cement Sandwich Panel is engineered with non-combustible reinforced cement surface layers on both sides that can withstand direct exposure to 1000-degree-Celsius flames for up to 4 full hours, with no structural damage or burning through. Unlike pure organic foam insulation materials that release thick toxic smoke during a fire event, the cement-bonded EPS core inside these panels produces extremely low levels of harmful smoke, giving every employee far more safe evacuation time during an emergency. Almost all local fire safety departments now fully recognize these panels as a code-compliant wall system for large corporate office buildings, drastically simplifying your fire permit application process and reducing annual commercial property insurance premiums for your facility.
