How can fire-resistant doors and Windows meet one-hour fire resistance at present

At the present stage of the refractory doors and Windows market, the fire Windows that can meet the fire resistance for 1 hour are basically steel frame or steel and wood composite frame plus composite fire glass in principle. Therefore, the aging performance is poor. Because the steel frame is not extruded, it can not meet the sealing requirements of air tightness, water tightness and so on. 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.

- Brief description of fireproof expansion seals for clad doors and Windows

Coated doors and Windows fireproof expansion seal is made of PE outer coating, high resilience PU foam as the main raw material, containing PP skeleton, so the fireproof expansion seal has less than 10% compression change form, to ensure that it can be applied in doors and Windows, coated fireproof expansion seal sealing, PE outer coating greatly increase the service life of the product, Not only the color is rich and gorgeous, but also there are more choices. The PP skeleton in this material also has a very good fixed effect on the product, which can effectively prevent the product shrinkage after successful installation.

- Cause of abnormal sound after installation of aluminum alloy fire window

Have you ever had this problem? There is no problem for users who live in high-rise buildings to check the aluminum alloy fire Windows after the developers hand over the room, but the wind will ring, causing a lot of trouble, and the sound like blowing whistle continues to spread to the ears, which is almost a collapse. Most residents have changed the Windows, but there are also some who feel that they can make do with it, and the sound continues like this, so where is the problem? What's the solution? Aluminum alloy fire window such a problem we have to check, see is the wind or the window resonance sound, is generally not well sealed, window frame and glass edge gap, the simple solution is to stick a wool can be, there is the whole window frame edge sealant, so as to effectively reduce the resonance sound. So now check in or buy aluminum alloy window friends pay attention to this problem, find professionals to install Windows, seal must do a good job, can protect our life and property safety and no noise harassment, customized aluminum alloy fire Windows suggest you choose regular manufacturers cooperation, not only quality assurance installation worry-free, factory price is also appropriate, welcome to consult us.

- Describes the fireproof expansion strip

We all know that fireproof window is a kind of fireproof glass window that meets both fire integrity and heat insulation integrity. Fireproof window is a whole composed of fireproof glass, frame, fireproof expansion bar and so on. They work together to ensure the complete performance of fireproof window. 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. Fire Windows should be installed on the outer walls of two buildings with insufficient fire spacing, or between Spaces separated by firewalls, when lighting and ventilation are needed. 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.

- Selection criteria for fire-proof window materials

Heat insulation and fire Windows are made of inlaid grout fireproof glass inside the frame structure. They are used for lighting, transparency and ventilation in daily conditions. When a fire occurs, they have the function of isolating smoke diffusion and blocking thermal radiation, which is a commonly used fire prevention product in buildings. According to the different materials of the window frame, there are mainly aluminum, steel and other metal fire Windows. At present, most of the fire Windows on the market are made of steel, which has stable performance and good heat resistance. The fire rating of fire Windows is divided into A, B and C. The fire resistance of Class A Windows is not less than one and a half hours, that of Class B Windows is not less than one hour, and that of Class C Windows is not less than half an hour. And the material selection of each component of the fire window is also a certain standard, it can be said that the quality of the fire window is determined by the material of its components. According to the new production specification GB16809-2008 for fire window Z, the selection of fire window materials shall be in accordance with the following technical requirements: 1. The frame adopts a steel frame with a certain strength that is sufficient to ensure the integrity and stability of the component. 2. The filling materials inside the frame should be non-combustible materials. 3. Galvanized steel plate can be selected for steel frame and laminate. Its material selection standards should meet the GB12955 "steel fire door general technical conditions" in 5.1 provisions. 4, fireproof glass selection of fireproof window fire resistance test qualified products. Glass transmittance should be greater than or equal to the same number of ordinary plate glass 75%. 5, the sealing material between the frame and the fireproof glass should be inflammable material, which can play the role of fire prevention and smoke insulation in the event of fire. 6, hardware accessories should be qualified by the test of the matching products. These are the selection standards of fire window materials organized by Xiaobian.

- 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?
