Nowadays, many people are renovating their homes. Whether they are replacing windows or sealing balconies, everyone will choose broken bridge aluminum windows. But most people don’t know the difference between regular broken bridge aluminum windows and system windows?

When you visit the building materials market, you will find that the price ofordinary bridge-breaking windows on the market starts from about how much Prices range from hundreds to thousands of yuan per square meter, while some brands of system windows are as expensive as three to four thousand yuan per square meter.

Xiaodong has a friend who has been running business in the door and window industry for many years. He revealed to me: You can Ordinary broken bridge aluminum doors and windows and system doors and windows are compared to assembly of computers and brand computers, so that everyone may understand them better.

System doors and windows have their own R&D team, including profiles, cavities, overlaps, as well as thermal insulation and sound insulation strips, overall sealing, mid-level connectors, etc., all of which are owned by their own R&D team.

After the product has been molded, tested, debugged, and sent to a third party for testing to achieve various performances, the product will be mass-produced. Putting it on the market. This also requires the company to have a certain degree of strength to develop professional system door and window products.

System doors and windows are mainly expensive in terms ofprofiles, hardware,andR&D design, comprehensive performance, etc. The so-called“You get what you pay for” Distribution\”.

Ordinary broken bridge aluminum windows are more flexible than system windows, and components can be configured according to your own needs, the materials required for doors and windows can be selected from domestic and foreign manufacturers.

Secondly, the production cost of ordinary broken bridge aluminum windows is low and the price is relatively cheap. Small factories of the Broken Bridge Aluminum Brand generally spend about 150,000 to buy a set of door and window processing equipment, and then rent a space to process and produce doors and windows.

Basic materials such as profiles, hardware, corner codes, and insulation strips can all be purchased directly from the market, and then processed and assembled according to the different needs of customers.

The most important point is the difference in production technology. Ordinary broken bridge windows aremechanically assembled. Glue injection. The corners of the system window mechanical unit are glue-injected, so it has better performance and stability.

How much does it cost to choose system windows or ordinary broken bridge windows?

In fact, there is no unified standard for the price of system windows. It depends on what brand of aluminum is used, what brand of hardware is used, and whether the glass is double-layered or triple-layered. is the determining factor of price.

For ordinary broken bridge windows, if you choose the cost-effective 65-85 series, domestic first-line hardware, three-layer insulating glass, the market price is average Between six hundred and one thousand.

What are the key points to look for when choosing broken bridge aluminum windows?

This friend of Xiaodong also helped everyone summarize the 6 key points to distinguish the quality of doors and windows. According to the following standards when purchasing, you will basically avoid pitfalls.

1. Model

Many people don’t know how to choose the model? Should I choose 65 or 85, or 108 or 120? What is the difference between different models? In fact, these models refer to the thickness of the window frame, which represents the width of the window sill. First of all, if you want cost-effectiveness, choose between 65 and 80, which is completely sufficient.

In fact, most of the very expensive 108 and 120 series are integrated window screens. The thickness is just the hollow distance of the aluminum material that is widened. In addition to looking good, it actually has no effect on thermal insulation, sound insulation and heat insulation. A big improvement.

2. Aluminum profiles

Profiles are equivalent to human skeletons. To distinguish good from bad, remember two points: first, whether the profile is virgin aluminum or recycled aluminum. The surface of the virgin aluminum section looks smooth and uniform. Second, the wall thickness of the profile is important. It is the key to determining the stability and safety of windows. The minimum standard must be 1.4mm. Currently, the new national standard requires a wall thickness of 1.8mm to meet the standard. Those with a wall thickness of 1.2mm are basically the same. It’s recycled aluminum.

3. Thermal insulation strip

Thermal insulation strip, which connects the two aluminum materials inside and outside, is equivalent to bone and bone The connected ribs mainly serve to block the energy transfer of the aluminum profile. PA66 is generally used on the market, but PVC is also used as insulation strips. PVC material is easy to crack and age when exposed to wind and sun. Nylon PA66 can withstand high temperatures of 300 degrees. The quality is obvious. The simple test method is to burn it with a lighter, but it will not light up.

4. Sealing strip

Adhesive strip, it It ensures the sealing of doors and windows. Because balconies are often exposed to wind and sun, EPDM rubber strips must be used. This is on the same level as the sealing strip on the door of our car. It has strong anti-aging ability and will not make a whistling sound no matter how strong the wind is outside.

5. Hardware

Hardware accessories are also called doors and windows The heart of the system, whether it is easy to use and safe, the hardware is critical. Ask the merchant whether the hardware is domestic or imported. Good hardware can guarantee the switch.It\’s smooth and won\’t break down for decades. Domestic brands includeHaobao, Dinggu, Jianlang, Guoqiang and Rongji. If you are not short of money, you can use German imported brands such as Haobao, Noto, Silkilia, and Himek.

6. Glass

It is important to choose window profiles , but the largest area is not the profile, but the glass. Whether windows can truly save energy and whether they are safe, the key factor is glass. Therefore, compared to aluminum profiles, the choice of glass cannot be ignored.

The thickness of the glass should be selected according to the area of ​​the window. Generally, the thickness of glass is 5 mm, but if the area of ​​the glass exceeds two square meters, it is recommended to choose a thickness of 6 mm or more. Secondly, tempered glass must have the 3C certification mark. You must check the code below to see if it is tempered by a regular manufacturer.

If you want good thermal insulation effect, choose three-layer insulating glass. It is recommended to reserve 9 to 15 mm for the hollow part. If the distance between the hollows is too large, it will easily cause gas convection, which will affect the effect. .

If the house faces the street, square, or is in a downtown area, you should choose laminated insulating glass and close the window. Two worlds. If you want to be economical, double-layer insulating glass is the most cost-effective. src=\”https://p3-sign.toutiaoimg.com/tos-cn-i-qvj2lq49k0/4e95fff1fc1c42ad8921449eb4ab1b41~tplv-tt-origin-web:gif.jpeg?_ iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1737853022&x-signature=%2FgSPuNqlPmL%2BRHakE8kwQqrsz4Q%3D\”/>

In the end: the so-called three points depends on the product and seven points depends on the installation. Will the windows leak in the future? There is also a direct relationship between safety and security

Therefore, you should also pay attention to these points during installation:

• When removing the original windows, be sure to supervise the workers not to damage the extension walls The integrity of the structure should be maintained to avoid water seepage in the interior wall in the future.
• Be sure to keep an eye on it, and the distance between the fixed points of the windows must not be greater than 60. Centimeters.
• The window needs weather-resistant glue and foam sealant. You must buy a good quality brand of glue, and the sealing effect will be good even if it is applied
• Make sure that water can be drained in time if there is a slope.
• If you choose to open the window, be sure to hang a safety chain to avoid the risk of falling.
