Hi: I have installed two replacement windows and the sliding glass door. As you can see in the photo, there are gaps that need to be filled before trim is placed. Is it better to fill with regular fiberglass insulation or the foam insulation that comes in a spray can? Also, for the windows, they are attached to the exterior wood frame, but loosely. The instructions say to not overtighten the screws because it may distort the window frame. The bottom screws are in good. For the top side screws, if the screws were inserted now, because of the window and frame placement, the screw would not make contact with the wood frame. Is it normal for the window to be in, but not secured in a super tight fashion? Thanks.

Hey guys.. I have some water damage on the bottom of my door frame on the outside trim pieces, that has bled thru to the inside. I want to repair the siding piece on the outside, but I noticed that the "frame" piece that goes all around the door has rot too. It looks to me like this is some kind of kit that comes with all the pieces because the wood is connected with teeth on one side and grooves on the other to lock all the pieces together. My question is, do I need to buy a whole new kit? Is this a difficult job? I am handy just want to make sure I fix it right and stop all water from getting inside and ruining my new baseboards I put down in kitchen. I've already ripped all the inside trim pieces from around the door to replace those, just want to fix outside first. I have 2 pieces of 1x4" cedar to replace the outside trim pieces, but once I removed it I noticed rot deeper into the frame than I thought. Any advice is appreciated, i've included a pic of my problem area [URL=http://s136.photobucket.com/user/jsb91010/media/20130414_143823_zps3eb26715.jpg.html][IMG]http://i136.photobucket.com/albums/q199/jsb91010/20130414_143823_zps3eb26715.jpg[/IMG][/URL]
