windows
I am a retired contractor and as a rule always used grace ice and water at all windows. Grace around all edges, install window and then grace over flange and it sticks together. Never had a leak. Back in the day windows were wood and we put a spline around opening. For all you youngins out there a spline was a 6 in. strip of felt paper. Then they made window flashing rolls of Grace thank god. Also we used red rosin paper before house wrap. I guess I am a dinosaur that loves to fish!
