Hollow glass is a high-performance building material with the following characteristics:
1. Good insulation performance
The air layer or other inert gas layer (such as argon) in the middle of the insulating glass can effectively prevent the transfer of heat. Because the thermal conductivity of gas is much lower than that of glass, it can reduce the exchange of indoor and outdoor heat. For example, in cold winter, it can slow down the dissipation of indoor heat to the outside, keeping the indoor environment warm; In the hot summer, it can prevent outdoor heat from entering the room, reduce the frequency of air conditioning use, and play an energy-saving role.
2. Good sound insulation effect
Its special structure has a good barrier effect on the propagation of sound. When sound passes through different media, it undergoes reflection, refraction, and absorption. The air layer in insulated glass can absorb and reflect some of the sound, reducing external noise entering the room. For example, using insulated glass in buildings near roads or noisy environments can effectively reduce various external disturbances such as traffic noise and human voices indoors, providing users with a relatively quiet environment.
3. Anti condensation function
When the temperature difference between indoor and outdoor is large, ordinary glass surfaces are prone to condensation. Hollow glass, with its insulation layer in the middle, reduces the temperature difference between the inner and outer surfaces of the glass, thereby reducing the possibility of condensation. For example, in cold weather, windows with insulated glass are less prone to water droplets on the surface. This not only maintains the transparency of the glass, but also prevents mold growth and damage to surrounding facilities such as window frames caused by condensation.
4. Excellent optical performance
Hollow glass can provide good lighting effect and effectively reduce glare. It can allow sufficient natural light to enter the room, while also scattering and filtering the light to a certain extent, making the indoor light softer and more uniform. And it can also be coated as needed to further control the transmittance and reflectivity of light. For example, low emissivity coated insulating glass can reflect infrared rays, ensuring natural lighting while reducing the entry of solar radiation heat.
5. High security performance
Compared to ordinary single-layer glass, insulated glass has higher strength. Even under external impact, the likelihood of it breaking is relatively low; And even if the outer glass is broken, the inner glass can still remain intact, and the fragments will adhere to the adhesive layer in the middle, reducing the risk of glass fragments splashing and causing harm to the human body, which to some extent improves the safety of the building.
6. Long service life
Hollow glass has good sealing performance. As long as the quality of sealant and other materials is qualified and installed correctly, it can maintain its performance for a long time. Under normal circumstances, the service life of insulated glass can reach 15-20 years or even longer, reducing the trouble and cost caused by frequent glass replacement.
