The advantages of Asian aluminum alloy doors and windows are very prominent. It has durability, stability and excellent material firmness. It is applied in large-area buildings such as Sunshine rooms to give full play to the advantages of aluminum alloy in the field of overall deformation resistance, sound insulation, heat insulation, excellent product permeability and drainage system structure; Sub-material aluminum alloy doors and windows have extremely high comprehensive performance, and the ultra-modern appearance is fashionable and simple, which highly meets the needs of consumers.
Decoration preferred Asian aluminum alloy doors and windows
In the crucial market of aluminum alloy doors and windows, most of our first choice for buying doors and windows is aluminum alloy doors and windows. If we buy aluminum alloy doors and windows, we will think of asian aluminum alloy doors and windows in the first place, with excellent quality, moreover, broken bridge insulated aluminum alloy doors and windows have the functions of heat preservation, heat insulation, sound insulation and noise reduction, and the sealing and water resistance are excellent.
Traditional ordinary doors and windows use single-sided glass, which is integrated with aluminum alloy frame. Because metal and glass are easy to transfer heat, the thermal insulation performance is very poor. Asian aluminum alloy doors and windows adopt broken bridge structure, and the glass adopts 5 12A 5 hollow glass. 12A is the thickness of the air layer between the two pieces of glass, so the heat transfer of the glass is also isolated by the air layer, which is a bit like the principle of kettle, so the broken bridge structure plays a good thermal insulation insulation.
Why are the doors and windows you bought so expensive?
He bought it so cheap?
Just like a shoe
Some shop price is 100 yuan
Some shop price is 300 yuan
No comparison, no harm!
Today, let's talk about the price difference between doors and windows!
1. Materials
Profile thickness
The doors and windows of the same model look from the outside
External size specifications of materials are the same
But the thickness is different!
Wall thickness is 1.4mm,1.6mm,1.8mm,2.0mm, so many specifications
The thicker the profile, the higher the cost
Heat insulation strip
Heat insulation strip has the function of heat insulation
The quality of the heat insulation strip is not good, and the heat insulation effect cannot be achieved.
The strength of the form will also be greatly reduced.
Ordinary broken bridge doors and windows use pvc insulation strips of thousands of yuan per ton to reduce costs
Brand doors and windows in order to achieve the set thermal insulation coefficient
It is common to use more than 20000 tons of PA66 nylon insulation strip
Only this point, the material price difference is several times!
Profile brand and raw materials
Due to different production equipment and quality requirements
The processing fee of profiles of the same specification is different.
The price difference can reach thousands of yuan per ton.
Aluminum rod also has native aluminum rod and regeneration aluminum rod
Their price difference is also several hundred yuan per ton
2. Hardware
The prices of hardware of different brands are very different.
They have the same color and function
However, a product from a well-known manufacturer has been sold in the market for many years and has a relatively high reputation.
The other is the imitation produced by a small workshop, which has the same appearance.
But their materials, production processes, and surface treatments are different.
Therefore, the service life and safety performance are not at the same level at all.
Third, craft
Same material in different manufacturers
There is also a huge gap in the manufacturing process.
Small doors and windows manufacturers assemble doors and windows only by assembling doors and windows firmly
In addition to being firm and beautiful, the doors and windows assembled by regular large factories
First, apply angle glue to the section of aluminum.
Glue inside the corner
Fill the gap between the corner code and the profile with a corner glue
Make them a whole
That is, the connection is stronger, and it can prevent the corner from leaking.
At the same time, there is another step on the air tightness.
There are also mid-end connection, milling precision, hardware assembly, etc.
There is a difference between small workshops and brand doors and windows manufacturing technology.
IV. Door and window performance
It is common that doors and windows only meet the basic requirements of doors and windows that can be ventilated, daylighting and shelter from wind and rain.
Brand doors and windows have higher requirements on air tightness, water tightness, wind pressure resistance, energy saving and noise reduction, and safety.
Especially the u value of doors and windows, the lower the u value, the better the thermal insulation and energy saving of doors and windows
To understand the data of doors and windows, understand its heat insulation effect, sound insulation effect, sun shading effect and energy saving effect
This is why Germany's high-quality doors and windows can sell thousands of yuan per square meter in the market.
V. Safety factor
Ordinary open bridge doors and windows are locked by only two locking points. Thieves can easily pry open the window by using tools.
System doors and windows are distributed in windows from two original locking points to six locking points and six locking points in hardware accessories.
The above points are the reasons why asian doors and windows are so expensive.
