how do I use my bedroom and walkin freezer for recording?

I want to use my bedroom (with bed) and an old walkin freezer to record in. this will by no means be professional. I hope to do more recording of my bands demo here and maybe some other demos. I still need to upgrade gear, but I know the acoustic treatments are very important and want to start the process now. the freezer is 8x8 typical metal insulated panels fairly soundproofed but needs treatment I know. I am mostly concerned with soundproofing out road noise as I am only 50-100ft off a highway. bedroom is 11x13 fire retardent sheetrock with 30"french doors opposite 40X45 window centered on the walls and the door to the freezer on a third wall center. what removeable treatment can I do to the window? to the door? what acoustic treatments can i do inside the freezer to improve it? I was thinking OC703 insert for the window, maybe a free standing 703 panel in front of the door and/or using markertech blankets? where can i find how many db reduction I can get with these products? I have been reading for hours and doing searches I hope i didnt break protocol. :roll:

Protocol's fine Billy; a sketch of some sort would be useful though. Also, by "db reduction" if you mean soundproofing, I'm sorry; absorption within a room does essentially NOTHING to change how much sound gets in or out - only mass, and preferably mass-air-mass, works to do that. You might check out the REFERENCE section - there's a link there on window plugs, plus a lot more useful info. You can find it near the top of the Construction forum. If your walk-in is a cube, don't expect anything you do to make it sound REALLY good; nothing short of moving a wall can fix that, although some panel traps could help - I'm not sure what your skills/willingness/budget are yet... IF you re-read the "Don't even THINK..." post at the top of each forum, it will give you a good jumping off point and the more of the bold points you can answer the easier it will be to help you get going...
