- Standard for aluminium alloy window and door profiles
2023-01-14 14:22
The standard wall thickness of aluminum alloy door and window profiles should be determined by calculation or experiment, in addition to the bar, buckle plate and other elastic assembly profiles, the main force of the door profile base material section Z small measured wall thickness should not be less than 2.0㎜, the main force of the window profile base material section Z small measured wall thickness should not be less than 1.4㎜.
The wall thickness of aluminum alloy door and window profiles 55 and 85 series is the national standard 1.4mm. The wall thickness of the 110 series profiles of the broken bridge aluminum door and window brand is 1.5mm, and the upper and lower tolerance will not exceed 0.1mm. The series of profiles are different, and the aluminum insulation strips of insulating glass are also changed.
Broken bridge aluminum profile as an upgraded version of aluminum alloy, whether toughness strength or wind pressure level will certainly be much higher, many people are easy to be fooled when buying, originally choose 1.4mm wall thickness can be, after the brainwashing of the business chose 1.8mm, in fact, in the case of unnecessary we choose 1.4mm can.
Broken bridge aluminum doors and Windows as a hot topic in home decoration profiles, many people do not know how to choose this kind of products, especially the wall thickness of the profile needs no psychological bottom, in fact, according to the national standard external wall building broken bridge aluminum doors and Windows wall thickness requirements of more than 1.4MM, if it is the use of sliding doors and doors as indoor, usually reach 1.1 wall thickness.
A lot of people will ask, isn't it OK to have thicker walls? Not no, if you choose too thin profile, the wind pressure performance is relatively poor, especially in the typhoon level weather, this is a very dangerous thing,
The glass and hardware of broken bridge aluminum doors and Windows are also very important. Kangying doors and Windows 5+27A+5 insulating glass can stand the test in sound insulation performance and wind resistance.
General standards for aluminum alloy profiles:
1. Profile wall thickness: The wall thickness of the usual home decoration products shall not be less than 1.4mm, and the detailed thickness shall be selected by the designer. Then the wall thickness of less than 1.4mm are classified as non-standard goods;
2. Heat insulation strip: heat insulation strip is a key part of the broken bridge aluminum profile, the state regulations are necessary to use PA66 nylon strip, some manufacturers on the market use cheap PVC plastic heat insulation strip, which will affect the use of goods life;
3. Glass: broken bridge aluminum doors and Windows are necessary to choose hollow glass of different thickness, the original piece is float glass, the thickness specification is 5mm, the thickness of the heat insulation strip between two pieces of glass is between 12mm- 15mm, according to the door and window profile standard setting;
4. Doors and Windows adhesive strips: adhesive strips should be imported EPDM products, whose service life is up to 30 years, and the general life of damaged goods is only about 5 years.

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.
