Panels to cover windows

[tinymontgomery]

Hi,

I've been searching for information on this but couldn't really find anything so I'd figure I'd ask. My studio/band room has 3 windows to the outside that I really want to cover up and try to reduce outside leakage. The catch here is I don't want to do something completely permanent like just brick over the windows, so I was thinking about building some type of acoustic paneling in that would cover the window and fit snug along the outside of the molding. I was thinking of a frame, a layer of insulation against the window, a layer of either wood or sheet rock, and then another layer of insulation with fabric covering it so that once I'm done the window would just look like another acoustic panel on the wall in the room.

So...has anyone done anything similar to this? Do you really think it would help with the outside noise?

At little more info on the room, it's an extra upstairs bedroom on my house that just has sheet rock walls...nothing really special.

thanks,

Tiny

I just did two windows and made a huge difference! Start with covering the window with something to prevent it unsightly from passerbys (mabe thin pegboard?),then place two sheets of 703,alternating direction.Anchor in two strips of 1X2's along the sides.Place a sheet of thick MDF, screwed to the 1X2's.Screw a second mdf sheet(glued to the first with green glue or liquid nails) to the first,ALTERNATING Direction.Add two layers of alternating drywall board and seal all gaps with a resilient RTV.This will really help with traffic noise bleeding into your mics. Select your mdf and wallboard thicknesses to guage where the ''new wall'' will sit with the existing.I painted to match my wall: upstairs master bedroom...

That's certainly doable. Just make sure to insulate the cavity you create with then mass (drywall or wood). The more mass you can add to your side (as 1 layer or multi-layers with no gap), the more isolation you can achieve.

Can you please explain what you mean by the part that I put in bold? If I'm not mistaken, MDF has no grain, being it is basically sawdust, woodglue, and a few chemicals.

Basically did the same thing and the only thing you could hear outside the building, if anything, was slight leakage through the floor (we were on the first floor) and out the garage door and that's only if it was really quiet.

During normal business hours you couldn't hear a thing outside.

Great for rehearsal and not too critical recordings.
