Fire protection doors

Fire protection closures ensure that fire and smoke cannot spread through the door openings in fire-resistant partition and fire walls – because the doors installed there are self-closing and effectively stop smoke and fire.
Fire and smoke resistant doors are required in:
• long corridors,
• stairwells,
• fire-resistant partitions and firewalls,
• emergency exits,
• escape routes for isolation.
• buildings with high visitor frequency.
• private houses between the living area and the garage.
Fire doors close automatically and have a certain degree of fire resistance. They prevent the passage of flames, smoke and hot combustion gases for a certain period of time. The time span is indicated in the name of the door: there are T90 and T30 doors that can withstand fire for 90 or 30 minutes. The doors are divided into “fire resistance classes”.
A fire door must be mounted according to regulations. Installation instructions will be supplied by the manufacturer together with the door parts.
Customer should receive necessary info purchasing the door:
• DIN standards for suitable fittings,
• possibly the mention of alternative fittings,
• the naming of certain manufacturers, whose products must be used
The fire door must also be provided with an approval document/sticker. It must indicate:
• the manufacturer
• the fire resistance class
• that the door is monitored
• the year of manufacture
• Fire protection doors regulations staircase

Smoke protection doors for safe stairs and corridors

Smoke is often many times greater than the damage caused by the flames.
The typical locations where smoke protection doors must be installed:

• the space between the stairwell and the exit, if a stairwell does not lead directly outside.
• Stairwells leading to: Basement, undeveloped roof spaces, workshops, shops, storage rooms, rooms larger than 200 m² but not living space.

Fire doors can have both fire resistance and smoke protection function.
