One, Is it useful to install soundproof and fireproof windows?
Adding an acoustic and fire-resistant window refers to installing a new window directly along the interior side of an existing window, without altering the original structure. If the installation process meets the required standards and the product performance is good, the added acoustic and fire-resistant window can effectively achieve sound and noise insulation, as well as fire protection. Furthermore, adding an acoustic and fire-resistant window does not require modifying the existing building structure, making the installation process more convenient.

II. How to install soundproof windows
Install a new window that is identical in appearance to the original one, effectively creating a double-window effect. The new window is installed within the existing window frame, maintaining the original opening for ventilation and airflow.
If the original window is a swing-open window, then the installed soundproof window is also a swing-open window. If the original window is a sliding window, the dimensions depend on the width and size of the sliding window. based on the specific site conditions, determine the opening width and size of the soundproof window. Generally, soundproof glass weighs about half the weight of ordinary hollow glass. If the opening width is too large, it is easy to deform and lose its seal. Therefore, the opening width of the soundproof window should be between 35-65 cm. Standard opening widths are typically 50, 55, and 60 cm. The specific opening width should be determined based on the site conditions.
