In modern buildings, noise pollution has received increasing attention. As an important part of the building envelope, the sealing treatment of the broken bridge casement window with the wall plays an extremely critical role in noise reduction.
First of all, good sealing treatment can effectively block airborne sound transmission. When sound propagates in the air, if there is a gap between the broken bridge casement window and the wall, the noise will easily penetrate like an "all-pervasive" airflow. For example, when sound waves such as outdoor traffic noise and industrial noise hit the window, only by filling the tiny pores between the window frame and the wall with sealing strips, foaming agents, etc. can a barrier be built to prevent noise from entering the room with air as the medium. The quality of the sealing material and the installation process directly determine the tightness of this barrier. High-quality sealing strips have good elasticity and resilience, and can fit the window frame and the wall tightly. Even after the window is opened and closed or used for a long time, it can still maintain sealing performance and minimize airborne sound transmission.
Secondly, sealing treatment is of great significance in reducing structural sound transmission. When external noise causes the wall to vibrate, if the window is not tightly connected to the wall, the vibration will be transmitted to the room through the window frame. The sealing treatment of the broken bridge casement window and the wall is like setting a buffer zone between the two, absorbing and dispersing part of the vibration energy through flexible sealing materials. For example, the expansion foaming agent is used to fill the connection between the window frame and the wall. It can not only seal the gap, but also buffer the vibration to a certain extent, preventing the wall vibration from being directly transmitted to the window frame and then transmitted to the room, effectively reducing the noise interference caused by structure-borne sound, and making the indoor environment quieter and more comfortable.
Furthermore, the integrity of the sealing treatment affects the stability of the overall noise reduction effect. A small sealing loophole may become a "breakthrough" for noise. In the actual installation process, the sealing of corners, window sills and other parts is easily overlooked or improperly handled. If these parts are not well sealed, even if the main body of the window frame is well sealed, noise can still enter the room from these weak links, destroying the overall noise reduction effect. Therefore, construction personnel are required to strictly follow the specifications to ensure that the broken bridge casement window and the wall are seamlessly sealed at all connection parts, and to ensure the durability and stability of the noise reduction effect as a whole.
Finally, with the development of architectural acoustic technology, the requirements for the sealing of broken bridge casement windows and walls are also increasing. New sealing materials and processes are constantly emerging. For example, the use of high-performance composite sealing strips combined with advanced window frame installation and positioning technology can further improve the sealing effect and provide a stronger guarantee for reducing noise. In the process of building design and construction, paying attention to the sealing of broken bridge casement windows and walls is an important part of creating a quiet indoor environment and improving living quality.
