We are in the process of renovating an 1850's School house and I am a little perplexed.
I have just replaced all the windows and are in the process of ripping off all of the old Aluminum and Cedar Shake siding on the building (Cedar was underneath). Anyway, when we installed the windows we put a 3/4 inch ferring strip underneath the window flange to bring the window out slightly. This was done because we are installing 3/4 in rigid insulation to the house as well as extra thick Cedar Shakes and did not want the window to look like it was sitting in a "hole". The windows will be flashed with Vycor and capped with a drip edge and a 1x4 board will be used to "frame" the windows. The house will be wrapped in Weathertrek.
Should I bring the Rigid insulation over the flange of the window and frame on top of that or should I frame the windows first, cap and butt the foam up to the frame? If I do this I will have to stack two 1x4's for depth.
Any advice would be appreciated.
