The evolution of windows is a process of constant quest by the masses and reserach and development by the manufacturers. Every few years it will be updated to make up for the defects of the previous product.
The mainstream of the current market is broken bridge aluminum windows, which are characterized by many links and accessories. First of all, a window includes different parts such as window frame, glass, hardware, adhesive tap, etc. We often say which brand of windows, in fact, the main thing to say is the window frame, that is, the profile manufacturer's brand.
Window frame: that is, the profile. Aluminum ore mining are first melted into pure aluminum ingots, aluminum ingots and then melted, adding other metals, made of aluminum alloy rods, and then use the profile machine to pull into a variety of profiles, profiles and then processed into window frames.
That is: aluminum ingot → aluminum bar → profile → window frame
This aspect of window frame profiles, when buying windows you will often hear numbers like 60, 65, 70. This is actually refers to the width of the window frame.
60 means that the window frame profile including insulation strip is 60mm wide, 65 means 65mm and so on. No matter what series, it should be determined according to the size of the window opening and the local wind pressure value. However, as a window wall thickness of the main force bar should not be less than 1.4mm. 65 is generally the same as 60, only the insulation bar becomes wider; 70 wall thickness is 1.6mm or 1.8mm.
In fact, broken bridge aluminum is mainly added a heat insulation bar, some will use ordinary PVC heat insulation bar, some with nylon PA66 heat insulation bar.
Generally speaking, we use PA66, high temperature resistance, not afraid of expansion. And glass: if it is a high-level, floor-to-ceiling windows, or windows larger than 1.5 square meters, try to use tempered glass, high hardness, glass broken will also become granular together, will not hurt people. Now all tempered glass has a CCC mark on a corner. It is important to note that the best tempered glass have 3% self-explosion rate, generally are not affected by external impact and the glass itself cracked a piece of pattern. (However, we do not have to worry, self-blowing is relatively mild. And for this situation there is a way to use double laminated tempered glass, not afraid of self-explosion, self-explosion will be glued, will not be scattered.)
Now the broken bridge aluminum windows will generally use insulating glass, in order to acheive the thermal insulation effect generally choose 12mm and above the thickness of the hollow, both sides of the glass should be 4-5mm thickness. Double insulating the best should be 5mm+25mmA+5mm, A is expressed in the middle of the air layer degree, the other on behalf of the thickness of the glass, the inuslation effect of the thick layer of insulating effect is better, the most basic is 5+12+5; triple recommended 5+9A+5+9A+5.
Generally in order to prevent children from hitting, in the distance from the ground below 1m glass should also be tempered, insulating glass is two layers, only tempered inner layer can be. If the business can not do low-e film, try not to coat, the other coatings are very affect the indoor light. After the glass is coated, you can see the outside from the inside, and the outside can't see the inside, and it also protects against ultraviolet rays.
About hardware: good hardware ensures smooth opening and closing of windows for decades. If the window is good, the hardware is not good, it will affect the sealing, heat insulation and heat preservation performance. Hardware is generally charged separately, accordingly to each set of sales, note that unscrupulous merchants will sell the hardware by parts, different openings of the window hardware is not the same.
For example, the hardware of casement windows mainly consist of handles, actuators, hinges, locking points, wind braces, which is a complete set of hardware.
