\n\u2714 It prevents flames from spreading via ventilation.
\n\u2714 It slows heat transfer and protects structures from overheating
\n\u2714 It maintains smoke extraction functionality
\n\u2714 It minimizes the concentration of hazardous carbon monoxide during emergencies.<\/p>\n

Regulatory document:<\/strong>
\nSP 7.13130 (fire resistance limit\u00a0EI 15\u2013EI 150<\/strong>\u00a0depending on the ventilation type and smoke removal calculation).<\/p>\n<\/div><\/div><\/div><\/div>
