As far as the time in installation is concerned, it depends on various specific factors. These include the volume of windows to be installed, standard or custom-made, and the nature of the site or structure to be sound resistant. There are applications where only custom-made sound resistant windows are installed after a comprehensive survey. In such cases, it might take a few days for the installation. On the other hand, in the standard cases, it is just like a plug-and-play job only.
