Thermal break aluminum doors and windows have gradually become a popular fashion in modern home door and window decoration. As an important part of the doors and windows, glass has good light transmittance and thermal insulation effect, making the life better.
So, what types of glass are usually used with these thermal break aluminum doors and windows? What are their functions? What are the properties and advantages of insulated glass, laminated glass, laminated insulated glass, and LOW-E glass commonly used in the market for broken bridge aluminum doors and windows? Let's go to see:
Insulated glass is a composite structure formed by the use of an air layer. By combining two or even three layers of glass, a noise barrier is created, which blocks the intimate contact between air and the outside world. It can effectively isolate the propagation of sound and achieve noise reduction function.
Insulated glass has a good sound insulation effect on high-frequency noise, such as speech and school horns. However, its sound insulation effect on low-frequency noise such as traffic is not very ideal, such as train noise, airplane noise, engine noise, etc., because insulated glass resonates with low-frequency noise in the low-frequency range.
Laminated glass refers to a layer of PVB adhesive layer added between two layers of glass, forming a damping layer that absorbs low-frequency sound waves, suppresses glass vibration, and achieves sound insulation effect. Moreover, laminated glass is much thicker than ordinary glass, with strong vibration resistance and explosion resistance, making it a recognized safety glass.
The sound insulation effect of laminated glass is very good for both high-frequency noise and mid low frequency noise. Therefore, double-layer or multi-layer laminated glass is widely used in high-end soundproof doors and windows, especially tempered laminated glass, which plays a crucial role in the construction of sunrooms and is generally used in high-end hotels, nursing homes, and other places.
Insulated laminated glass combines the advantages of laminated glass and insulated glass. Various outdoor noise and sound waves gradually attenuate through the air layer and adhesive layer, especially when the noise passes through the adhesive layer, the mid to high frequency noise is absorbed, distorted, dampened, and attenuated, which can eliminate about 95% of the noise
Compared with ordinary insulated glass, laminated glass has more outstanding sound insulation effect due to the increase in glass weight and the matching effect of laminated glass being far away from mid to low frequency traffic noise. It also brings safety properties; Compared with ordinary laminated glass, due to the low thermal conductivity of the hollow layer air, the energy-saving effect is more excellent.
Different types of glass can be selected according to one's own needs: insulated glass is preferred for high-frequency sound insulation (such as speech, horn, car horn, etc.); For low-frequency sound insulation (such as train noise, airplane noise, car engine noise, etc.), choose laminated glass; If your budget is sufficient and you have a high demand for sound insulation, then choose laminated insulated glass.
