ice behind window J channel
I am seeing icicles forming above windows and doors behind J channel. house is less than a 1yr old. house has 1/2" osb with tyvek, I installed the window tape, windows have new construction flanges and I caulked around opening when I installed them. has just standard grade vinyl siding, also getting a lot of condensation on inside of windows also. I haven't came across this problem before.
