The window is located in RED's base, right outside of this spawn door:


​
You can spam projectiles out of this window... such as pipes, stickybombs, etc.

​
Pipes spammed from this location land around the bridge.

​
But you can also charge up your Stickybomb Launcher and fire stickies out of the window, like so:

​
Fully charged stickies fired from this spot will actually end up all the way over here!

On BLU's base!

You can also sticky/rocket jump on to a lamp post that is right next to the outside of the window.

Notice how you can see inside of RED's spawn doors from this angle, for some odd reason.
​
You can spam projectiles through the window and they will land directly in or in front of RED's spawn room.

​
(This angle is obviously more beneficial if you're on BLU team and want to spawn camp RED players.)

Thanks for checking out my guide! I hope you found it useful.
