Insulated glass and laminated glass are common soundproof glass, how to choose?
Insulated glass is a glass assembly composed of two or more pieces of glass, separated by an aluminum frame filled with high-efficiency molecular sieves, and sealed with high-strength sealant at the edges. It has the characteristics of sound insulation, heat insulation, and heat preservation.
Laminated glass is composed of two or more pieces of glass with one or more layers of organic polymer intermediate film sandwiched between them. After special high-temperature pre-pressing and high-temperature and high-pressure processing, the glass and the interlayer film are permanently bonded as a composite glass product.
Both insulating glass and laminated glass have the effect of sound insulation and heat insulation to a certain extent. However, laminated glass has better shock resistance and explosion-proof performance, while insulating glass has better heat insulation.
In terms of sound insulation effect:
Laminated glass has good seismic performance, so when the wind is strong, the noise caused by its own vibration is small, especially for medium and low frequencies, it is an ideal soundproof glass for busy traffic arterial roads.
The insulating glass is prone to resonance and is not suitable for use on traffic arteries. For isolating external noise, insulating glass has more advantages and is more suitable for home decoration.
Therefore, according to different places, the glass to be selected is also different. For example, in the application of the sun room, the top of the sun room generally uses laminated glass, while the facade of the sun room uses insulating glass. Because if you encounter falling objects from high altitude, the safety of laminated glass is relatively high, shards of glass will not fly and cause injury. The use of insulating glass for the facade glass can better achieve heat insulation while sound insulation, and keep the sun room warm in winter and cool in summer.
