Types and requirements of aluminum alloy door and window glass for building
The largest area of aluminum alloy doors and windows is the glass component. In addition to the ornamental value of glass, due to the requirements of thermal insulation and energy saving, double-layer insulating glass has been required for residential aluminum alloy doors and windows in some areas, and the minimum insulating glass configuration requirement is 5+6A+5. According to different building structure types, window-to-wall ratios, etc., through energy-saving calculations, different items need to be configured with different hollow layer thickness and glass thickness.
The glass commonly used in residential aluminum alloy doors and windows can be divided into tempered glass, laminated (sandwich) glass, low-e glass, coated glass, etc.
Description:
The representation of tempered glass is commonly used to mark "G" after the glass that needs to be tempered.
Safety glass refers to tempered glass, laminated glass, and glass composed of them. In the case of insulating glass, it is required that both layers of glass be tempered to be safety glass, and both pieces of glass must be marked with 3C.
Commonly used locations with safety glass configuration requirements are as follows:
a) Glass area ≥1.5m2
b) Floor-to-ceiling windows with floor-to-ceiling windows and bottom finishes ≤500mm
c) 7th and 7th floor open windows
d) Tilting the assembly window, skylight
e) Locations that are susceptible to impact and impact, such as all doors, floor-mounted glass, etc.
At present, the commonly used glass brands “Yaopi”, “Yangtze” and “Labor” refer to the original glass brand, which is the brand of ordinary single glass. All the subsequent processing processes of tempering, laminating, low-e, coating and other glass are carried out. In the glass deep processing unit, there are many glass deep processing factories that can complete the above processing capabilities. The aluminum alloy door and window manufacturers generally purchase the original film from the designated manufacturer, and then go to the glass deep processing unit that they often cooperate with.
According to different window types, the size of the window opening area, through the mechanical calculation, the thickness of the glass that may need to be configured for different window types in the same project is different. Generally speaking, the larger the glass area, the higher the glass thickness requirement. According to the different needs of customers, Malangwei Doors and Windows can freely customize aluminum alloy doors and windows products with different energy-saving requirements. In the glass selection level, to ensure the safety of the glass, the first thing to solve is the quality of the glass.
