One of the most effective ways to reduce loss of life and property during a fire is compartmentation systems that delay the spread of fire within the building. Compartmentation extends evacuation time and buys time for intervention teams by preventing fire and hot gases from passing from one section to another. Walls, ceilings, shafts, ventilation ducts and service penetrations used in passive fire protection systems are designed according to specific fire resistance classifications. In European standards, the EI classification indicates that protection against the passage of flames, hot gases and heat is provided for specific periods. Today, systems tested in accordance with EN 1364, EN 1365 and EN 1366 standards form the foundation of building safety. The use of correct fire-stopping systems is critically important especially in areas where mechanical and electrical services pass through. Firesol enhances the fire safety performance of projects with a wide product range from wall systems to service penetrations in fire compartmentation solutions.
