Insulation to put around sound proof window
« on: July 22, 2012, 04:47:38 AM »

My current windows are pretty crappy so I purchased some additional windows to sit on the interior window sill.

I bought two large 3 lite windows to add as interior windows for my house. They are big ones about 93" wide and 57" high and cost about $300 each custom ordered (Milgard). I asked the manufacturer to remove the fins and they did so to all of them except the bottom (presumably to protect the window and strengthen for shipping) one which was screwed to some wood. This I finally figured out how to remove by scouring both sides of the aluminum fin with a razor, then bending back and forth with some pliers until it broke off.

Now, I'm trying to figure out what to do next. The window is rather heaver so I took out the two sliders so it is lighter when lifting. After cleaning the windows completely, the plan is to lift the window to the sill then level it with some shims, screw it in and put some sort of foam or insulation around the gaps.

This window has no pre-drilled screw holes so I'm not sure where to put the screws and what sort of insulation or foam to put around the window. I was thinking of the spray foam stuff but I think if exposed to the sunlight that stuff disintegrates. I'm in Las Vegas, so the sun is pretty brutal.

Traditionally, I believe the fiberglass insulation is used around the window. The foam stuff seems nice, I'm just not sure if it will last and will be a pain to remove in the event that the window needs to be removed for cleaning.

Does anyone have any recommendations?

By the way, I'm going to remove the locks from the existing window so that I can easily open both the new window and then old one without unlocking.

I figured this is way cheaper than purchasing one of those specialty single pane soundproof windows.
