To reduce noise transmission through glass, you can employ various strategies that focus on improving the sound insulation properties of the glass itself or incorporating additional soundproofing elements. Here are some effective ways to reduce noise transmission:

1. Double or Triple Glazing: Double or triple glazing refers to the use of multiple layers of glass with air or gas-filled spaces between them. This configuration helps to block sound waves by creating an additional barrier. The air or gas-filled gaps act as an insulating layer, reducing the amount of noise that passes through the glass.

2. Laminated Glass: Laminated glass consists of two or more glass layers with an interlayer of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA) in between. This interlayer helps to dampen sound vibrations and improves the sound insulation properties of the glass. Laminated glass is particularly effective in reducing noise transmission, as it can significantly attenuate sound frequencies.

3. Acoustic PVB Interlayer: Upgrading the standard PVB interlayer in laminated glass to an acoustic PVB interlayer further enhances sound insulation. Acoustic PVB interlayers are specifically designed to reduce noise transmission and offer superior sound-dampening properties.

4. Increased Glass Thickness: Using thicker glass panes can help to reduce noise transmission. Thicker glass has more mass, which absorbs and dampens sound vibrations. However, it's important to consider structural requirements and seek professional advice to ensure the glass thickness is suitable for the specific application.

5. Window Treatments: Installing window treatments, such as heavy curtains, blinds, or acoustic panels, can help to absorb sound waves and reduce noise transmission. These treatments create an additional barrier and provide sound-absorbing properties that can improve overall acoustic insulation.

6. Cavity Insulation: Adding insulation material within the frame cavity between the glass panes can help to further reduce noise transmission. This insulation material absorbs sound waves and minimizes their transfer through the window system.

7. Proper Sealing: Ensuring a proper seal around the window frame helps to minimize gaps and air leaks that can allow sound to penetrate. Weatherstripping and sealants can be applied to seal any gaps or cracks, preventing sound from entering or escaping through these openings.

8. Distance and Orientation: Increasing the distance between the noise source and the glass window can help reduce the intensity of sound transmission. Additionally, orienting the windows away from the primary noise source can also minimize direct noise impact.

It's important to note that the effectiveness of these strategies may vary depending on the specific noise sources, the frequency of the noise, and the surrounding environment. For optimal results, it is recommended to consult with professionals experienced in acoustic design and consider the specific requirements and constraints of your building or space.

OUR solution was to add 1" insulated panels as the windows have been used as decorative parts of the façade. Silicone all the cavities and around the new panel
