Large City Windows
« on: May 01, 2018, 08:29:32 AM »
Hello there. Great site you have here, and I'd love the help of your expertise.

I'm in a brand new apartment on the second floor, right next to a busy street. The construction of the unit is actually quite good; it has concrete walls and triple pane windows, but it's not enough for the bedrooms. As far as I can tell the sound is primarily getting through the windows. We also want to block any outside light coming into these windows, so I'm not constrained to see-through solutions.

The window is 6.5' x 6.5'. Everything I've read about soundproofing suggests adding multiple layers of mass of different materials to help filter various frequencies. My current idea is to get a large sheet of plywood, attach a layer of mass loaded vinyl, and a layer of dense foam. I'm looking for advice if there is possibly a better solution or perhaps how to mount this monstrosity. Even just a single layer of MLV at this size sounds like it will be around 40 lbs per window which seems like it would be hard to secure in place. Also not sure how to prevent the edges from leaking sound- most recommendations I've seen is to use caulk or something similar, but I'm hesitant to do so as it will be difficult to restore when I move out.

These are my constraints: I'm allowed to put holes in the wall. Whatever I hang in the window has to be a solid neutral color from the outside. I need to be able to restore the unit back to the relative condition from when I moved in. The unit is brand new, so they will probably be fairly nitpicky.

Thanks for your time. Any help or suggestions would be much appreciated.

Depending on how deep the window seal is would dictate if you can use one of our black out window plugs shown on link below.

Feel free to contact me direct.
