Fireproofing/Firewall

“A systematic process, including design, material selection, and the application of materials, that provides a degree of fire resistance for protected substrates and assemblies. Fireproofing is aimed to protect against intense and prolonged heat exposure which otherwise could cause collapse of unprotected equipment, leading to the spread of burning liquids and substantial loss of property. Fireproofing may also mitigate concerns for life safety and environmental impact by reducing escalation.”

“A fire-resistance-rated smoke-tight walls having protected openings, which restricts the spread of fire and extends continuously from the foundation to or through the roof, with sufficient structural stability under fire conditions to allow collapse of construction on either side without collapse of the wall.”
