The market for broken bridge aluminum doors and windows is becoming increasingly large, and home decoration owners have higher requirements for products, such as performance, operational experience, and installation services. Today, we will teach you how to buy broken bridge aluminum doors and windows.

1、 Cross-sectional analysis of the performance of aluminum doors and windows with broken bridges

Firstly, the aluminum door and window section of the bridge cutoff includes many things, such as wall thickness, cavity, insulation strip, sealant strip, molecular sieve, insulation cotton, and so on.

1. The wall thickness editor suggests that the latest national standard 1.8mm should be used as the entry-level selection. Generally, products with thicker wall thickness also have better wind pressure resistance. For high-rise buildings and large areas, it is best to choose bridge cut aluminum doors and windows with a wall thickness of 1.8-2.0mm.

2. The insulation strip with a vertical isotherm has better performance, which can effectively block the transfer of outdoor heat to the interior. It is durable and does not deform, and the sound insulation effect is also good. Here, it should be emphasized that many people say that the wider the insulation strip, the better. In fact, 2-3 centimeters is about the same. If it is too narrow, it will affect the insulation effect, but if it is too narrow, it will affect the stability of the entire product.

3. Of course, in addition to insulation, the sealing performance cannot be ignored. When opening a fan, it often needs to go through the test of scorching sun and rain. EPDM sealant is relatively reliable, and it is necessary to choose a good brand of adhesive strip, otherwise it will become prone to air and water leakage in a few years. When looking at the cross-section, you can also see how many seals there are. Nowadays, better products have three seals, Also, it is recommended to use an integrated bending foam adhesive strip for the glass hollow lining.

4. Energy conservation, insulation, and waterproof performance are also areas of concern to many people. This product is mainly used in cold regions such as North China and Northeast China, and adding insulation cotton to walls is a basic operation for many manufacturers.

2、 Broken Bridge Aluminum Doors and Windows Viewing Glass

1. Common types of glass include: insulating glass (double layer insulating glass 5+20A+5, triple layer insulating glass 5+12A+5+15A+5, energy-saving insulation, and ordinary sound insulation are sufficient), laminated glass (hollow 5+15A+1.14+5), and low glass (coating+low radiation). Of course, these numbers are only used for inspection, and the actual situation can still be determined on-site.

2. Glass can be selected in this way: if you want better sound insulation performance, you can choose a hollow+laminated configuration. If you want energy-saving and insulation performance for a long time, you can choose a three-layer hollow glass. The thickness of a single piece of glass usually starts at 5mm. If a single piece of glass exceeds 3.5 square meters, it is recommended to choose 6mm. If a single piece of glass exceeds 4 square meters, you can choose an 8mm thick configuration.

3. The simplest and most direct way to recognize 3C certification (regulatory safety certification) is to scrape your nails. Usually, what can be scraped off is fake certification. Of course, it is best to have a certification report to check, and safety comes first.

3、 Experience of Operating Broken Bridge Aluminum Doors and Windows and Looking at Hardware

1. Firstly, the height of the handle is recommended to be around 1.4-1.5 meters, which is relatively comfortable to operate. Of course, everyone has a different experience, so let’s consider the actual situation.

2. The sealing performance of the opening fan is not only important for the sealant, but also for the locking points. Personally, I think at least the upper, middle, and lower locking points are relatively firm, greatly improving the sealing performance of the broken bridge aluminum doors and windows.

3. The importance of handles and hinges is not inferior to that of aluminum and glass. Handles are frequently used in daily life, and both operational experience and quality are crucial. Furthermore, hinges bear the burden of avoiding opening and dropping. Therefore, when choosing accessories, try to choose some brand hardware, and if you are willing to give a few square meters to a merchant who opens, you should pay attention.

4、 Installation of broken bridge aluminum doors and windows

1. Frame and glass dimensions: If the frame and glass are too large for the elevator, they will need to be lifted up the stairs, which will also incur some additional costs.

2. Window size ≠ hole size: It is important to communicate with the master of the measuring scale, as in addition to factors such as tiles and sills, the surrounding areas of the door and window frames need to be filled and fixed after installation. If the size is too small, it is necessary to chisel the hole. When filling the gap, the door and window frames and the wall should be fully filled without leaving any gaps.

3. Door and window frames usually need to be fixed with screws before applying foam, usually one at 50cm. Remember that the screws are threaded onto the aluminum material, not through the insulation strip.

5、 Contract for Broken Bridge Aluminum Doors and Windows

When signing a contract, it is necessary to clarify the materials, delivery time, pricing method, heat ownership, warranty, and after-sales service.

1. It is best to include the model, wall thickness, aluminum, glass, hardware, adhesive strips, etc. used in the contract to avoid later disputes, as verbal promises do not have legal effect.

2. The delivery time also needs to be well communicated, such as your decoration progress and the time provided by the merchant.

3. The calculation formula for the product, such as how much is it per square meter, how much is it to open a fan, and whether there are any additional auxiliary material costs.

4. Division of responsibilities for damages occurring during transportation, installation, and use.

5. Warranty and service life: such as how long the glass is covered and how long the hardware is covered.

The above are some suggestions for buying broken bridge aluminum doors and windows, hoping to help everyone!
