In our time, all buildings are designed according to the rules and regulations established to prevent fire, how to localize fires, methods of evacuation of people from dangerous areas during a fire. Fire-resistant metal Doors are an integral part of fire barriers that prevent the spread of fire within a specified time. The main purpose of fire doors to stop the fire in one place, avoiding penetration of smoke and its neighboring. Such a metal structure to maintain fire within the time specified in the certificate. Testing of the fire is carried out in special laboratories.
Fire doors should be chosen in such a way that if the office had a fire and will burn it all, the integrity of the door is not disturbed. On average, flat, covered by the elements, burn for 15-20 minutes. Warehouses can be burn longer (due to equipment and synthetic finishes: walls, floors, ceilings, furniture). Hence the conclusion: it is desirable that the fire resistance of doors was at least 30 minutes. These doors are both deaf, and entirely of glass or partly glazed, and they may be single-wing or folding. Fire-resistant glazing can provide effective protection of objects from the fire and smoke to locate fires and prevents the spread flame.
Used glass exhibit excellent transparency, which allows you to install them in administrative, industrial and residential buildings. They are widely used in the construction of doors, windows and translucent walls. Fire protection glazing is divided into several main classes: Class E. The degree of protection from flame and combustion products. Glasses provide protection only for this class Fire resistance can not localize the heat flux in this regard in a protected housing a high probability of ignition of inflammable objects. Class I. The degree of protection from the heat. Glass with high insulating properties. Class EI. The degree of protection from fire, combustion and high temperatures. When installing the glazing of the class provides the highest protection for a specified time. Class W. Degree of protection heat flow. This is a high-melting glass, do not let the heat. Class EW. Protection against flames, heat and combustion products. If you install fire-glazed with the degree of protection for a specified time will be ensured the safety of the building, people and property. The figure comes after a class of fire safety, means the amount of time during which the defense is valid, for example, EI-30 provides protection from fire, gas and high temperature for 30 minutes.
