Although SGP laminated glass is also used in the construction industry and some places, its field is not as extensive as PVB laminated glass, mainly for the following reasons:
1. Cost factor: The production cost of SGP laminated glass is relatively high, resulting in its higher price in the market compared to PVB laminated glass.
2. Recognition: SGP laminated glass, as a new type of building material, has relatively low recognition in the market. Many architects and developers have insufficient understanding of its performance and advantages.
3. Application limitations: SGP laminated glass has superior performance in all aspects compared to PVB laminated glass, so it is usually not used in general construction projects. It is mainly used in high-end construction projects with high requirements for safety, weather resistance, and other performance.
4. Technological maturity: The production technology of PVB laminated glass is relatively mature, and there are a large number of manufacturers and product choices in the market. The production technology of SGP laminated glass is relatively new, and currently only a few manufacturers can produce it, and there may be some differences in product specifications and quality.
5.SGP laminated glass is commonly used in high-rise buildings for curtain walls, doors and windows, skylights, ceilings, stairs, railings, as well as in places or locations with high safety performance requirements such as shops, banks, shop windows, partitions, and underwater projects that require impact resistance.
The application of SGP laminated glass in glass curtain walls is more common abroad, but there are also some buildings in China that use SGP laminated glass for glass curtain walls, such as the Caohejing Development Zone Headquarters Park, Kunming Planning Hall, and so on.
stay In this case, more attention should be paid to the water resistance, drug resistance, corrosion resistance and transparency of SGP laminated glass.
Doors, windows, skylights and ceilings applied to high-rise buildings
This requires SGP laminated glass to have higher light transmittance and thermal insulation performance to provide better indoor light and thermal comfort.
from Considering the glass substrate, float glass or high transmittance tempered glass will be selected.
from Considering interlayer thickness, properly control interlayer thickness, reduce Less light refraction and scattering.
Considering the interlayer material, increase thermal insulation materials, such as vacuum layer or thermal insulation gas, to reduce heat transfer.
