Door core:<\/b> It is made from special materials such as high-density fire-retardant chipboard, calcium silicate boards, or layers of basalt mineral wool. These slow down heat transfer.<\/span><\/p>\n

Intumescent seals:<\/b> This is a crucial component. The seals are installed on the edge of the door or on the frame, and at high temperatures (above 150\u2013200\u00b0C) they expand several times in volume, completely sealing the gap between the door and the frame to block the passage of flames and hot smoke.<\/span><\/p>\n

Certified hardware:<\/b> Hinges, locks, handles, and automatic closing systems (door closers) must be certified for fire resistance. They are made from materials that do not melt or fail quickly at extreme temperatures.<\/span><\/p>\n

Door frame:<\/b> It is usually made from treated solid wood or fire-resistant composite materials, completing the protective barrier.<\/span><\/p>\n

Doors are classified according to European standards, the most common markings are: <\/span>EI 30<\/b>, <\/span>EI 60<\/b>, <\/span>etc.<\/b><\/p>","protected":false},"excerpt":{"rendered":"
