- What are the types of fire resistant window profiles?


What are the differences between fireproof window profiles and ordinary Windows? The main difference between fire Windows and ordinary Windows is that the fire resistance is very strong, if the fire can be very effective for our escape and rescue to increase the time, slow down the expansion of the fire. So how long is its specific refractory time?

In fact, the principle of this kind of window is very simple, mainly composed of steel window frame, steel window sash, fireproof glass. But here to explain that fire window is not really fire, fire window only played a temporary role in resisting the spread of fire.

They also have different fire grades, the national unified provisions of fire Windows can be divided into A, B, C class, different fire grades represent different fire time. The fire resistance limit of Class A fire window shall not be less than 1.5 hours, Class B fire resistance limit shall not be less than 1 hour, Class C fire resistance limit shall not be less than 0.5 hours.

But in fact, the fire window is not casually can be set up, it also has a certain setting requirements. Include:

1, in the window sill wall does not meet 0.8 meters, if the solid wall is not set up, it is needed to separate.

2, two buildings do not meet the fire spacing, and in the side of the firewall window, you need to use A fire prevention.

3. If there is only one evacuation ladder for high-rise residential units, it needs to be set up.

4, the firewall should not be located in U, L shape and other high-rise buildings inside the corner. When it is located near the corner, the horizontal distance between the doors, Windows and holes on the walls on both sides of the inner corner should not be less than 4m; When the adjacent side is equipped with a fixed Class B fire window the distance can be unlimited.

5, close to the firewall on both sides of the door, window, the horizontal distance between the Z near the edge of the edge should not be less than 2m; When the horizontal spacing is less than 2m, fixed Class B fire doors and Windows should be set.

6, the firewall should not open doors, Windows, holes, when it must be opened, should be set up to close the Class A fire window profile.

In addition, there is the temperature sense window closure of ordinary fire Windows are external, very affect the architectural beauty, difficult to popularize in large areas of residential buildings, and the current use of ordinary broken bridge aluminum Windows, so the fire time can not reach the requirement of 1 hour.


- What are the applications of graphite rods besides fire-proof expansion rods?

The expanded carbonized layer formed by expandable graphite carbon has excellent heat insulation and high temperature resistance. The application of expandable graphite in flame-retardant plastics is mainly based on its expansibility and adiabatic property. For example, the expansion of graphite sheets dispersed in polyurethane foam can prevent combustion, reduce the fire, but also play a role in heat insulation.

This shows the importance of fireproof expansion tape.


- How to select high quality fire window profiles

First of all, Xiaobian first to tell you, what is the fire window profile. Fire window refers to the window that can meet the requirements of fire stability and fire integrity in a certain period of time, together with the frame.

The main function of fire Windows is to isolate and prevent the spread of fire, this kind of Windows are mostly fixed Windows. Another function is to light the house. This type of window has movable sashes to light and ventilate the house normally. In case of fire, it can play the role of fire prevention and separation. Fire Windows with movable sashes shall have manual and automatic closing functions. Therefore, it is very important to choose the fireproof window profile with excellent quality.
