Comparison of sound insulation between laminated glass and insulating glass
● 1. Sound insulation Angle
From the point of view of sound insulation, the same thickness of the laminated glass than hollow glass insulation effect is better, such as hollow 5mm glass +10mm hollow +5mm glass, the sound insulation effect must not be as good as 5mm glass +1mm film +5mm glass this structure, a layer of laminated film thickness is 0.38, general window glass with two layers of film,6+0.76+5, The thickness is about 12mm, and the noise attenuation is about 40db. This is because the insulating glass will produce resonance under the action of middle and low frequency sound waves, which will amplify the noise just like beating a drum.
● 2. Laminating material
The laminated glass with PVB intermediate film can block sound waves and maintain a quiet and comfortable office and living environment. Moreover, because of its good seismic performance, the noise brought by its own vibration is relatively small when the wind is strong. The sound insulation performance of the insulating glass is mainly determined by the actual thickness of the two layers of glass and the distance between the two pieces of glass. In general, home decoration generally uses more insulating glass, more suitable for ordinary families, but the sound insulation effect of laminated glass is certainly superior.
Whether the laminated glass is dry or wet.
Advantages and disadvantages of dry clip
● 1, the advantages of dry clip
Complex process: each process of dry clamping should not be taken lightly, and the finished product has the effect of reflecting sound waves.
Safety: IT IS INSTALLED ON DOORS AND Windows WITH THE function OF sound insulation and noise reduction. Even if the glass is broken due to collision, the fragments will be stuck on the film, and the broken glass surface will remain clean and smooth. Effectively prevent the occurrence of debris injury and penetration falling events, to ensure personal safety.
Strong resistance to penetration: the firmness of the dry clip is stronger and the hardness is higher.
● 2. Disadvantages of dry clips
Poor stability: it is easy to burst when processing, testing the workmanship of workers.
Advantages and disadvantages of wet clamp
● 1, the advantages of wet clamp
Safety: The safety performance of the wet clamp is also very high, the glass will not cause splashing after breaking, to prevent the splinter injury.
There are many kinds of laminating: there are many kinds of laminating of wet laminated glass, there is no limit on the size, and the selection range is large.
● 2, the disadvantages of wet clamp
Yellowing and degumming: wet laminated glass is easy to be affected by ultraviolet radiation for a long time, yellowing and degumming phenomenon is more, and the anti-aging performance is poor.
