Because glass is a liquid and it sags over time.
because of your sound waves bouncing off the glass
Cars warm up to a temperature higher than the surroundings because of the glass in the car windows. This is called the greenhouse effect. High-energy heat waves from the sun are able to pass through the glass of the windows, and this energy is absorbed by the materials inside the car, causing it to heat up. The glass does not let the less energetic heat waves being let off by the warm car pass through the windows. Therefore the heat is "trapped" inside the car, causing it to get warmer than the surroundings.
Sound waves propagate as a longitudinal waves. Any wave has some frequency and some wavelength. More the frequency more energy it possesses and hence its intensity increases so when such a wave hits something you can sometimes see the object vibrating. Also sound waves do not travel in space.
Sound reduction windows are designed with multiple panes of glass and insulating materials to block out noise from outside. This helps to minimize noise pollution in residential or commercial settings by creating a barrier that absorbs and reflects sound waves, reducing the amount of noise that enters the building.
Waves can pass through glass because glass is a transparent material that allows light to transmit through it. When waves encounter the glass, the atoms and molecules in the glass material vibrate but do not absorb the light energy, allowing the wave to continue propagating through the glass.
Glass breaks when exposed to sound waves due to a phenomenon called resonance. When the frequency of the sound waves matches the natural frequency of the glass, it causes the glass to vibrate intensely, leading to its breakage.
Soundproof windows are designed to block out external noise by using materials that absorb or reflect sound waves. This helps to reduce the amount of noise that enters a home or office, creating a quieter and more peaceful environment.

If the sound waves are strong enough the shattering of glass occurs when glass vibrates at the same frequency as the sound waves on the outer surface of the glass, but at lower frequencies inside the glass. This causes interference in the waveforms moving through the glass, which stress the glass, causing it to break. This is a different effect than when a single sharp sound, such as an explosion, pushes the glass beyond its breaking point.
The sound waves produced by the vocal chords contain energy and this energy is transmitted though the air to the glass, sound waves are pressure waves. The glass vibrates in resonance with the pressure variations and energy builds up in it to the point where it can shatter.
glass, windows really anything that you can see through.
