Recently, many netizens have inquired about balcony sealing and are confused by the price gap between doors and windows. The editor also calculated the psychological prices of some netizens and found that everyone is still very sensitive to price. According to incomplete statistics, there are currently at least 50,000 door and window processing shops and brand door and window manufacturers across the country. There are about 3,000 door and window companies in Guangdong, accounting for only one-tenth. However, no more than 50 of them have truly formed a brand influence. , but only one percent of the total.

Why are counterfeit door and window products much cheaper than genuine ones?

1. Genuine doors and windows have their own brands and patents, and they have been carefully developed with money and experience. Counterfeit products It’s just a counterfeit product, so there is basically no need for R&D costs;

2. Doors and windows need to be inspected for quality. Counterfeit products do not undergo quality inspection during the rush period. Their factory is a small workshop and they are not qualified to do quality inspection. The cost Low;

3. The hardware accessories used in copycat products are domestically produced low-quality, low-cost materials, or even recycled, and the aluminum content does not meet the standards;

4. Copycat companies They often just do it once and then run away. The brand has been killed by them. They change the address and name to build another brand. There is no so-called after-sales service, which greatly reduces the cost.

Why are there so many local door and window processing shops and small processing factories? The reason is also very simple: large market demand, developed logistics, low technical content, weak awareness of intellectual property rights, and low industry entry barriers.

Then the question is, what is the difference between brand-customized doors and windows and locally processed doors and windows? Why is it expensive? Where is it expensive? Why are brand doors and windows so expensive? What’s so good about the product? The editor went to the building materials market to explore and share with you the workmanship and quality of branded doors and windows.

First of all, let me introduce to you the broken bridge aluminum.

Nowadays, when doors and windows are mentioned, broken bridge aluminum is mentioned. The "bridge" in the name "Broken Bridge Aluminum" refers to the "hot and cold bridge" in the material science sense, and the word "broken" means action, that is, "breaking the hot and cold bridge. Specifically, because aluminum alloy is Metal conducts heat relatively quickly, so when the indoor and outdoor temperatures are very different, aluminum alloy can become a "bridge" to transfer heat. If doors and windows made of such materials have poor thermal insulation properties

< p>The broken bridge aluminum disconnects the aluminum alloy from the middle. It uses heat insulation strips to connect the disconnected aluminum alloys into one body, so that the heat is not easy to pass through the entire material, and the heat insulation performance of the material becomes better. , this is the origin of the name "Broken Bridge Insulated Aluminum"

Advantages:

A heat insulation layer is added on the basis of ordinary aluminum alloy profiles, and the heat dissipation is higher than ordinary aluminum alloy profiles. The number of doors and windows can be reduced by half, which can reduce heating costs by 30%; and it also has good sound insulation, heat insulation, fire resistance, air tightness, water tightness, anti-corrosion, thermal insulation, maintenance-free and other characteristics; and it is Metal aluminum profiles can be used for a long time without changing shape or fading.

Disadvantages:

The disadvantage is that the production process of aluminum materials is complicated and the production cost is relatively high. The price of ordinary broken-bridge aluminum doors and windows is around 800 yuan per square meter, and the price of high-end doors and windows from big brands is even more than 1,000 yuan.

Understanding the concept of broken-bridge aluminum, let me take a look at it. Why are the prices of branded doors and windows so high?

This time the editor came to Midea Doors and Windows, and thanked the staff of Midea Doors and Windows for their enthusiastic presentation and careful explanation.

01. Aluminum quality

Aluminum brands for balcony sealing include well-known first-tier brands such as Chinalco, Feng Aluminum, Guangzhou Aluminum, and Xinhe. There are also some second-tier brands produced by regular manufacturers, and there are also a large number of Recycled aluminum (scrap aluminum recycling) OEM.

For many netizens who do not want to choose first-line brands and consider price first, they must avoid choosing recycled aluminum. This kind of aluminum has poor toughness and is also contaminated by heavy metals. Question, how to distinguish recycled aluminum? Generally speaking, you cannot search for the brand and manufacturer address of recycled aluminum in major search engines, and the labels on the aluminum materials will exaggerate, such as "National Inspection-Free Product" and "National Famous Trademark" ""Germany"

So remember two points: (1) Unable to search, no formal manufacturer address, no formal contact information; (2) Exaggerated promotion of imported brand aluminum. You can relatively avoid "recycling" "Aluminum" is such a big pit.

As mentioned above, the cost of aluminum materials is very high, which directly leads to the high starting price of broken bridge aluminum doors and windows.

For price-sensitive netizens, it is recommended to choose primary aluminum brands that are less well-known but produced by regular manufacturers. Generally speaking, the quality is guaranteed.

For netizens who want to choose first-line brand materials, they must not be greedy for cheap!

02. Window details

45-degree splicing

The joints are made with 45-degree cutting feet, and the corner codes collide with the corner codes for splicing, which makes it stronger. Traditional 90-degree splicing requires screws to fix, and its strength is much worse than 45-degree splicing.

Glass strip sealing

The staff said that the glass in their home is fixed with sealing strips and sealant is banned. The sealant operation is simple, but the quality of the glue must be considered! If the quality is not good, on the one hand, the sealing effect is poor, on the other hand, there will be heavy formaldehyde pollution. Moreover, the sealant can easily cause spillage and affect the appearance.

First of all, the sealing strip looks neat and beautiful, is also very strong, and has a much longer service life.

But! Don't think that these simple reasons mean you can try sealing strips casually. The sealing strips used on doors and windows must be made of EPDM rubber! EPDM rubber is ozone-resistant, heat-resistant, and aging-resistant. It is mostly used in automobile parts. The sealing strips of car windows are all made of this material. Only this kind of material is strong enough to withstand the erosion of wind, sun, rain, and will have a longer service life. Of course, the price will be more expensive.

Glass thickness

First of all, tempered glass is a must. Then there is the width of the aluminum spacer. Generally, the size used in high-rise buildings is 5+12A+5. This data means that the thickness of the glass on both sides is 5mm and the aluminum spacer is 12mm. The thermal and sound insulation effect of broken bridge aluminum is closely related to the width of the aluminum spacer. The wider the middle spacer is within the allowable range, the better the effect. The staff said that all their models are equipped with the size of 5+20A+5, which is 20mm aluminum spacer, which has better heat insulation effect and is very effective for high-rise buildings! Of course, the materials used are different, so the price will also increase.

Hardware accessories

Good hardware accessories will bring a lot of convenience to life. Windows are frequently opened and closed, and repairs are inconvenient. Good hardware accessories can be used more smoothly and last longer. The staff said that the windows are equipped with original hardware parts and the cost is very high, which is one of the reasons why the price cannot be lowered.

After understanding these points, do you have a new understanding of broken bridge aluminum doors and windows?

Of course, good materials and quality are the guarantee of price, but the price is inflated There must be moisture.

I hope everyone can make a reasonable judgment on the price when choosing doors and windows in the future!
