What is hollow glass?
Hollow glass (INSULATING glass) was invented by Americans in 1865. It is a new type of building material with good heat insulation, sound insulation, beautiful appearance, and can reduce the weight of buildings, it is a high-efficiency sound insulation glass made by bonding glass Cover with aluminum alloy frame containing desiccant with two (or three) pieces of glass and using high-strength and high-air-tightness composite binder.
What is laminated glass?
Laminated glass (Laminated glass) Laminated glass is also called Laminated glass. It is the middle of two or several float glasses with strong PVB (ethylene polymer butyrate) adhesive film, which is combined with hot press pressure to discharge intermediate air as much as possible, then put it into a high-pressure steam kettle and use high temperature and high pressure to dissolve a small amount of residual air into adhesive film. Compared with other glass, it has the properties of shock resistance, anti-theft, bulletproof and explosion-proof.
So, laminated glass and hollow glass, which should I choose?
First of all, laminated glass and insulating glass have the effect of sound insulation and heat insulation to some extent. However, laminated glass has excellent seismic resistance and explosion-proof performance, while hollow glass has better thermal insulation.
In terms of sound insulation, there are different differences between the two. Laminated glass has good seismic performance, so when the wind is strong, the possibility of noise caused by its own vibration is small, especially for medium and low frequencies. However, hollow glass is prone to resonance.
But when it comes to isolating external noise, hollow glass has a slight advantage. Therefore, according to different places, the glass to be selected is also different.
If ordinary household, hollow glass is the most widely choice. If you live in high-rise buildings, the wind is strong and the noise is relatively small, laminated glass is also a good choice.
The most direct embodiment of the two kinds of glass is the application in the Sunshine Room. Generally, laminated double-layer tempered glass is used on the top of the sun room. The facade glass of the sun room uses hollow glass.
Because if you encounter high-altitude falling objects, the safety of laminated glass is relatively high, and it is not easy to completely crack. The use of hollow glass in the facade glass can better achieve heat insulation and keep the sun room warm in winter and cool in summer.
Therefore, it cannot be said that the double-layer laminated glass and double glazing unit glass are better. It can only be said that there is a greater demand in which aspect. Window glass is the knight who protects the family, and the most suitable one is the best one!
