Water Can Collect at Window Sills
Installing windows is tricky — A window is basically a big hole in an otherwise continuous surface that’s insulated and protected from rain and wind.
Builders have been putting windows in walls for a long time, so there are plenty of time-tested methods. But old houses weren’t insulated or air sealed as well as green houses, so drying was easier if the window leaked.

Dan,
Nice video...the sill is probably the most critical element.
How about some head details? Especially ones that incorporate outboard insulation and rainscreen.
That's where I am still scratchin my head.
Coming up
I'll get one up soon, John.
There are a couple more sill flashing videos in the windows section, under Builder Tips and down below.
