With the emergence of large buildings, high-rise buildings and super high-rise buildings in various places, energy-saving and artistic treatment of buildings is an important topic at present. Through the construction of energy-saving and artistically treated buildings, municipal construction and commercial buildings can achieve the effects of beautifying the city, rendering the living environment, showing the style of the times, and saving energy and reducing consumption.
Insulating glass curtain walls 1
Glass curtain walls (including doors and windows) have been widely accepted as an important means of building energy conservation and artistic treatment. The basic functions of glass curtain walls and glass doors and windows are wind, rain, lighting, energy-saving, sound insulation, and noise reduction. Bring the outdoor scenery to eight indoors, expand the visual space, and create a comfortable living and working environment; and have the function of beautifying and decorating the appearance of the building.

The glass currently used in buildings mainly includes the following categories: single glass, insulating glass, and laminated glass.
Single glass 1
Laminated glass 1
The following mainly introduces insulating glass: insulating glass is a product in which two or more sheets of flat glass are separated by a spacer frame and sealed with a sealant to form a dry gas space between the glass layers. With excellent properties such as heat insulation, sound insulation, anti-frost and anti-condensation, it is an indispensable door and window component in modern times, and it is also an emerging transparent wall material. The structural forms of hollow glass include: hollow glass is composed of two or more layers of flat glass. Use high-strength and high-air-tight composite adhesives around to bond and seal two or more pieces of glass with sealing strips and glass strips. The middle is filled with dry gas, and the frame is filled with desiccant to ensure the dryness of the air between the glass sheets. Various original glass sheets with different properties can be selected according to requirements, such as colorless transparent float glass patterned glass, heat-absorbing glass, heat-reflective glass, wired glass, tempered glass, etc. and frames (aluminum frame or glass strip, etc.), It is made by cementing, welding or welding. The space between the two pieces of glass is separated by a hollow aluminum alloy frame. The dry air and the desiccant in the aluminum alloy frame absorb the moisture in the glass space through the opening to keep the space extremely dry and airtight. Sealant (usually butyl rubber), high-strength adhesive (polysulfide rubber or structural glue).

1. Transparent Insulating Glass (take 6+12A+6 as an example)
Physical parameters: light transmittance: 80%; reflectivity: 15%: U value: 28w/m2k, Shading coefficient: 0.83; Sound insulation and noise reduction performance: Level 4, 35Db.

2. Low—E Hollow Glass (take milli-transparent type, light blue, 6+12A+6 as an example)
Low-E glass, also known as low-e glass, is produced by coating 1 or 2 layers of 10-20 nanometer silver metal on the original sheet of our high-quality float glass by vacuum magnetic air sputtering: tweezers have the lowest emissivity in nature The material can reduce the emissivity of the glass from 0 84 to O 1, or even lower, and reduce the radiant heat loss by nearly 90%, which is a high energy-saving product.
Physical parameters: light transmittance: 73%; reflectance: 12%; u value: 18W/m. · K;Shading coefficient: 0 69; Sound insulation and noise reduction performance: Level 4, 35Db.

3 Triple Glass and Double Hollow Glass (take transparent, 5+9A-4+9A+5 as an example)
Physical parameters: light transmittance: 74%; reflectivity: 21% i U value: 193w/m2 k:Shading coefficient: 0 81; sound insulation and noise reduction performance: level 5, 40Db.
Triple Glass 1
Comprehensive evaluation: beautiful and transparent appearance, good functions in all aspects, energy-saving and environmental protection, moderate price, and less follow-up investment.
