How to choose and install aluminum alloy sound insulation window
Generally speaking, there are three main factors that affect the sound insulation effect of windows: the air density of the doors and windows themselves, whether the glass specifications used are appropriate, and the construction quality of doors and windows during installation.
1。 In the part of "air density of doors and windows": the air tightness and sound insulation of windows are absolutely related. The air tightness is related to the overall design of the product. If the rubber strips and joints of doors and windows are not fully dense, the sound will be transmitted through the non dense gaps, which will affect the sound insulation performance. In addition, if the hardware parts are not assembled accurately, it is easy to shake and produce shaking or collision sound when there is low frequency in the environment. For this part, when purchasing windows, consumers can ask the manufacturer to issue a "sound insulation test certificate" issued by an academic institution or a certified qualified laboratory to ensure that the sound insulation effect of the product can meet their own needs.
2。 In the section of "whether the glass specifications are appropriate": the glass takes up a considerable area of the window, so its thickness and specifications will directly affect the performance of sound insulation. Generally speaking, the anti noise performance of glued glass is the best, followed by insulating laminated glass, and the sound insulation effect of single-layer glass is the worst. Therefore, if consumers have high requirements for sound insulation, they are advised to use laminated glass or even "laminated insulating glass" (glued + insulating + glued) with higher safety factor.
3。 In the part of "construction quality during installation of doors and windows": although consumers know how to require doors and windows products to have "sound insulation test certificate", the performance of sound insulation performance will also be affected if the door and window manufacturers do not check and adjust the accessories (such as adhesive strips, rollers, large and small sentences, and forced blocks) during construction. In addition, if the "dry construction method" is adopted for the doors and windows of the home, if the gap between the wrapping material and the old frame material is not filled with foaming agent, the water drops will fall on the window frame, and the echo of empty sound will appear, and even water seepage may occur.
However, the sound insulation effect of airtight windows is to block the transmission of sound sources. In some cases, the sound is transmitted by the RC (reinforced concrete) resonance (vibration) of the building structure, rather than by air. For example, the rooms near the building machine room and elevator room, or the houses close to the traffic arteries and viaducts, etc., the main noise sources are from At this time, the sound insulation effect of the reinforced concrete window cannot be exerted. In addition, sometimes the structure material of the building is too thin, or the cement grouting is not solid, or there are cracks in the wall, which are also the possible reasons for the poor sound insulation effect.
Having said so much, do you understand how to choose to install aluminum alloy sound insulation windows?
