Look at the wall thickness of the profile
according to the relevant national standards, the wall thickness of the main stressed parts of aluminum alloy window profile should not be less than 1.4mm, and the high-rise layer can reach more than 20 layers. You can choose to increase the thickness of the profile, the wall thickness of the main stress parts of heavy sliding door profiles should not be less than 2.0mm; The thickness of vertical hinged door profiles should not be less than 1.2mm; The thickness of a single door and window above 3-4 square meters can be thickened, and the column can be increased to increase the physical strength of doors and windows if it is too large. When purchasing, we should pay attention to whether the wall thickness of the profile of the product meets the specified national standard. If it does not meet the relevant standards, it will have a certain impact on the safety of doors and windows and the wind pressure resistance.

Look at the heat insulation strip
heat insulation strip is the core structural component connecting the aluminum structure of the Broken Bridge, and is loaded together with the aluminum to transfer the glass weight to the wall. If the quality of the insulation strip is not closed, the doors and windows will be deformed if it is light, and the structure of the bridge will be split if it is heavy, and the windows will fall directly!
At present, the insulation strips used in broken bridge doors and windows on the market are mainly divided into three levels:
first, imported glass fiber enhanced nylon insulation strip (PA66GF +25% glass fiber) represented by German Tylenol wind;
the second is the domestic nylon insulation strip produced in 2003;
the third is PVC insulation strip (because there is a big difference between PVC insulation strip and aluminum alloy linear expansion coeffcient, coupled with insufficient strength and poor aging resistance, etc., which have been eliminated by European doors and windows and curtain wall industries.)
however, the best heat insulation strip recognized is Tylenol wind heat insulation strip, because as one of the main drafting units of European standards and China's industry standards being determined, tylenol is recognized as the world's largest supplier of nylon insulation strips, with a global market share of 60%. So everyone is buying broken bridge aluminum doors and windows when, it is best to choose products with German Tylenol wind insulation strip.

Look at the glass
broken bridge aluminum doors and windows generally, the configuration of double-layer hollow tempered glass is adopted, and the design of double-layer hollow tempered glass generally plays the functions of sound insulation and heat insulation. When purchasing, you should pay attention to whether the '3C' certification mark appears on the tempered glass. Only the glass with the certification label is the regular qualified glass. You can choose different configurations of insulating glass according to the location, floor height, surrounding environment and other factors of the residence. The thickness of the glass and the width of the hollow layer will affect the sound insulation and heat insulation effects of doors and windows.
