Hollow glass is a glass product made of two or more pieces of glass that are effectively supported, evenly separated, and sealed around the edges, creating a dry gas space between the glass layers. Compared with ordinary glass, insulated glass has the following advantages:
1. Good thermal insulation performance
Ordinary glass has a single-layer structure and conducts heat quickly, while hollow glass has an air layer or is filled with inert gases such as argon in the middle. These gases have low thermal conductivity and can effectively prevent heat transfer, reducing indoor and outdoor heat exchange. For example, in winter, it can reduce indoor heat dissipation and maintain indoor warmth; In summer, it can block the incoming outdoor heat, reduce the rate of indoor temperature rise, and provide good insulation, making indoor temperature more stable.
The performance of hollow glass helps to reduce the energy consumption of buildings, decrease the frequency and duration of use of air conditioning, heating and other equipment, and achieve energy conservation and emission reduction.
2. Excellent sound insulation and noise reduction effect
The air layer or inert gas layer of hollow glass can serve as a barrier for sound propagation, buffering and absorbing sound, effectively blocking external noise from entering the room.
For residents living in noisy environments such as traffic arteries and near factories, using hollow glass can significantly reduce external noise interference, create a quiet and comfortable indoor environment, and improve their quality of life and work efficiency.
3. Good sealing performance
The periphery of the hollow glass is sealed with sealant, which can effectively prevent dust, rainwater, moisture, etc. from entering the air layer in the middle of the glass, keep the air layer dry and clean, and extend the service life of the glass.
In contrast, ordinary glass is prone to gaps during long-term use, which can cause dust and rainwater to enter, affecting the transparency and aesthetics of the glass.
4. Higher security performance
In general, insulated glass is composed of two or more pieces of glass. Even if one piece of glass breaks, the fragments will be limited within a certain range by other glass and sealant, making it less likely to splash and injure people, thereby reducing safety risks.
In addition, safety glass such as laminated glass can be selected as a component of the insulating glass as needed to further improve its safety performance and enhance its resistance to impact and external forces.
5. Adjustable optical performance
It is possible to coat the surface of hollow glass with different thin films, such as Low-E film, to give it different optical properties, such as reflectivity and transmittance.
This adjustable optical performance can effectively control sunlight according to different building and environmental requirements, such as reducing glare and improving indoor lighting quality, while also achieving certain energy-saving effects.
