Sealing and heat insulation focus on broken bridges! Heat insulation strip is the "bridge" of the broken bridge window "! Broken Bridge Aluminum is also called heat insulation broken bridge aluminum, which is to disconnect the aluminum alloy from the middle and connect it with heat insulation strips to effectively prevent the conduction of heat. Therefore, the quality of heat insulation strip directly affects broken bridge aluminum doors and windows the sealing effect.
Modern home decoration is often used broken bridge aluminum doors and windows, everyone newly installed broken bridge aluminum doors and windows looks exactly the same, from the appearance broken bridge aluminum doors and windows there is no difference, but there are many tricks! Next, let's introduce the editor. Broken bridge aluminum doors and windows I hope I can help you.

I. Profiles
1. Profile wall thickness
in the national standard, the basic wall thickness of ordinary aluminum alloy doors and windows is between 1.2 and 1.4mm, and the wall thickness of broken bridge aluminum windows must be above 1.4mm. However, the wall thickness of some fake and inferior products in the market is likely to not reach the standard of ordinary aluminum alloy doors and windows.

2. Heat insulation strip
sealing and heat insulation focus on broken bridges! Heat insulation strip is the "bridge" of the broken bridge window "!
Broken Bridge Aluminum is also called heat insulation broken bridge aluminum, which is to disconnect the aluminum alloy from the middle and connect it with heat insulation strips to effectively prevent the conduction of heat.
Therefore, the quality of heat insulation strip directly affects broken bridge aluminum doors and windows the sealing effect.

Broken bridge aluminum doors and windows PA66 nylon insulation strip must be used, which is stipulated by national standards, not PVC plastic strip. PVC strip luminous and shiny, but the surface is not smooth; The surface of the real nylon strip is smooth and symmetrical.
Once the heat insulation strip is deformed, it will not be tightly connected with the aluminum alloy profile, which will affect the sealing effect of the window. PVC heat insulation strip is easily deformed due to the influence of heat expansion and cold contraction; Nylon strip is characterized by firmness, firmness and stronger stability, it is not easy to deform.
Ordinary PVC insulation strips are generally about 6000 to 7000 tons, while PA66 nylon insulation strips are up to 28000 yuan per ton, which is why the price of doors and windows with the same appearance is much worse.

2. Glass
high-end brand of big factory broken bridge aluminum doors and windows, basically equipped with safe double-layer tempered insulation glass, excellent sealing and sound insulation effects, and safe performance.
Other types of glass include non-tempered hollow, single-sided tempered hollow, etc. The price difference among them can't be seen from the eyes of flesh. Some window glass is only dozens of pieces per square meter, while some glass is hundreds per square meter. In this way, the overall price difference of the window will appear.
Hollow glass with poor quality has poor sealing performance, which leads to water vapor entering the middle layer and forming fog on the glass, which not only affects the appearance, but also indicates that the air tightness and water tightness are obviously insufficient. Living in the same area, under the same environment, the doors and windows with good sealing performance can ensure that the home is warm in winter and cool in summer, isolating the noisy car sounds, human voices and square dances from the outside world, while the inferior doors and windows make the family suffer!

III. Accessories
1. Hardware
door and window hardware is most likely to be tampered with by some bad merchants.
Good hardware is usually made of copper, stainless steel or zinc alloy with high strength, not easy to deform, good corrosion resistance, stronger weight capacity and good stability.
However, the poor hardware is mostly made of ordinary metal materials, such as aluminum alloy and other materials with soft metal properties, which are easy to deform, break and hardware handle thin in Wall.

In terms of beauty and durability, good hardware needs to be polished, polished and electroplated, with finer surface treatment, acid alkali resistance corrosion resistance, smooth surface and easy cleaning. Poor hardware is easy to scratch the paint surface and fall off, easy to wear.
The cost of a set of inferior hardware may be less than 100, and the cost of good hardware may be as high as hundreds of sets. If it is imported hardware, the price is higher.
2. Sealant
on the market, sealant is mixed, there are 2 or 3 yuan per bottle, there are dozens of bottles and even dozens of 11 bottles. The cost of installing doors and windows varies depending on your choice.
Silicon sealant is acidic and neutral. Doors and windows generally choose neutral silicon sealant, which can prevent mildew and weather (high temperature resistance, low temperature).
Good sealant is environmentally friendly and tasteless, no stimulation, no harm to human health, inferior silicon sealant strong stimulation taste, unknown ingredients, is a major source of indoor pollution!

IV. Craft
the products of big factories and small workshops are not inferior in workmanship. Even if a small workshop looks like a cottage on the outside, it cannot compare all the performances of doors and windows with genuine goods brand doors and windows.
In the design of doors and windows, professional designers design not only the appearance, but also the doors and windows that are more suitable for practical use and can optimize the use value. Among them, how to make the sealing performance of doors and windows better, how to make the service life of doors and windows longer, small workshops can imitate the appearance but cannot imitate the real design.

In terms of the accuracy of cutting doors and windows, the equipment accuracy of small workshops is poor, the doors and windows produced are uneven, and they cannot fit with the wall surface during installation.

V. Service life
good quality door and window system can guarantee the service life of several decades, while inferior doors and windows will have various hidden dangers and problems after several years of use and must be replaced. For example, doors and windows bought at 400/㎡ are completely lower than the market price, it is possible it takes 5 years to change new products, and the cost of changing new products again and again is higher than buying high quality doors and windows at a time!
