I have my replacement window here now and am getting ready to put it in. It does fit nicely.
The window case sticks out further past the nail fin than I was expecting, I expect this is to allow for the thickness of the house wrap and siding, j-channel, etc. I'm not installing this where there will be siding around it, so that creates an issue. The case sticks out 1" past the fin, so I will need azek trim that is 1" thick (not 3/4"), or this is going to look really funny with the window case sticking out 1/4" past the trim. For this application, I probably would have preferred a nail fin that was all the way at the front of the case, like a sliding door would be. I could use something like brick mold, but I want something around 2.5" wide and 1" (full) thick.
Any recommendations? I would think that there would be dozens of azek style trim kits available for different styles.
Also, do I put a bead of sealant on the back of the nail fin, or is the protecto wrap enough? If so, what do I use for sealant?
