Hollow glass is a glass product that is evenly separated by two or more pieces of glass with effective support and sealed around the perimeter, so that a dry gas space is formed between the glass layers. Its performance and characteristics are as follows:
1. Thermal insulation: The air layer of hollow glass can effectively prevent heat transfer and reduce the thermal conductivity coefficient. Compared with single-layer glass, the thermal insulation effect is significantly improved, which can reduce indoor heat loss and reduce the energy consumption of air conditioning and heating.
2. Sound insulation and noise reduction: The air layer can buffer and absorb sound waves, effectively block external noise, and generally reduce noise by about 30-40 decibels, creating a quiet indoor environment.
3. Anti-condensation: Since the air inside the insulating glass is dry and the surface temperature of the glass is relatively high, in cold weather, it can effectively reduce the condensation on the surface of the glass and avoid problems such as mold and corrosion of the glass caused by condensation.
4. High safety performance: Holow glass generally uses two or more pieces of glass. Even if one piece of glass is broken, the other pieces of glass can still maintain a certain integrity, and it is not easy to fall and hurt people, which has a certain safety protection effect.
5. Beautiful and energy-saving: The appearance is simple and beautiful, and different colors and specifications of glass can be selected according to different needs. At the same time, good energy-saving performance meets the requirements of modern buildings for energy conservation and environmental protection, which helps to reduce energy consumption and reduce carbon emissions.
6. Long service life: Under normal use conditions, the sealing performance of hollow glass is good, which can ensure the stability of the air layer, and the service life can reach 15-20 years or even longer.
