The installation of fire protection doors and windows is essential, especially in public buildings, but considering their other additional features and benefits, they are becoming increasingly popular in private homes and apartments. Fire protection joinery is complemented by fire protection windows, which also provide protection against fire.
According to the Construction Law Act of 7 July 1994 and subsequent amendments and the Regulation of the Minister, buildings should be designed and constructed in accordance with current technical knowledge and ensuring fire safety. One section of the regulation deals entirely with the fire protection of buildings, escape routes and, among other things, fire zones. Door and window frames are one of the most important elements of a fire protection system that prevents the spread of fire and smoke and facilitates evacuation. The owner or manager of the building is responsible for the proper functioning of all fire protection measures and is obliged to check them at least once a year. In addition, they must keep records confirming that the fire protection system components are maintained in good technical condition.
The purpose of a fire protection system is, among other things, to contain the spread of fire and to facilitate evacuation. One of the most important elements of this system is the fire door. First of all, it acts as a barrier to fire and the spread of flames, thus protecting residents from danger and fire damage. Manufacturers offer a wide range of fire doors in terms of design, shape and type. They also have very good thermal and sound insulation properties and can be aesthetically pleasing. When it comes to the material from which fire doors are made, we can choose from steel, aluminium and wooden doors. In each case, they are available in solid, glazed or partially glazed versions and can also be burglar-proof. Of course, if they are to serve as external doors, they can be made in a suitable format, design and colour, if requested by the customer. Nevertheless, taking into account the functions that fire doors are to fulfil, we distinguish between several fire resistance classes.
The fire resistance class is the ability of a building element to meet certain requirements during a fire. The measure of fire resistance is the time from the start of a fire to when a building element reaches one of three limit criteria, expressed in minutes: The fire resistance class of a door is indicated by a combination of letters and numbers. The letter E stands for fire resistance, the letter I for fire insulation, and the letter W for the permissible radiation intensity. The number following the symbol indicates how long the fire door can withstand fire. For example, a fire door with the classification ei30 can withstand fire for 45 minutes. The following fire doors are mainly available on the market: EI30, EI45, EI60, EI90, EI120, EI180, EW20 and EW60. Fire doors
