When selecting aluminum alloy doors and windows, we all have a look, two touch and three smell methods and skills, so what are the small tricks when selecting high-end aluminum alloy doors and windows?
In fact, we can look at the insulating glass of doors and windows, and judge the quality of doors and windows by identifying the advantages and disadvantages of the insulating glass used. As long as you walk around the door and window market, you will find that there are many types of insulating glass. Although it seems that the materials selected are similar, the price is divided into many grades, from hundreds of low to more than 10000, which is hard to choose.
According to experts, the difference between true and false insulating glass is that two pieces of glass should be sealed with sealant strips first, and then filled with inert gas. This structure makes the real insulating glass doors and windows have good sound insulation performance. The special insulating glass of the above-mentioned is cheap, and the insulating glass has no effect on the insulating glass.
Now we know that we can judge the advantages and disadvantages of high-end aluminum alloy doors and windows by distinguishing whether the glass is "hollow", but how can we judge whether the glass is "hollow" glass? First of all, we can observe whether the glass is sealed. The color difference between the two adhesives can be clearly seen from the appearance of real insulating glass, and only one color of black polysulfide glue can be seen in false hollow glass; only two layers of glue can ensure absolute sealing.
Secondly, there is an aluminum partition between the two pieces of real insulating glass, and there are many air holes on the aluminum partition strip. The desiccant can absorb the moisture in the gas and prevent the glass doors and windows from being foggy after being heated. However, the false "hollow" glass does not have these devices.
Thirdly, the aluminum strip between the glass can be clearly seen from the front because of the lack of butyl rubber sealing in the false insulating glass, while the aluminum strip covered by butyl rubber can only be seen from the side of the real insulating glass. Finally, from the sound insulation effect, the real insulating glass insulation effect is very good, and the false sound insulation effect is no different from the ordinary, it is easy to distinguish.
