Based upon what I saw, that window will leak. The window wrap alone isn't sufficient. If/when the water penetrates past the trim and is repelled by the window wrap, it is still, at that time, into the wall cavity. The answer is to install house wrap or plastic vapor barrier before you insert the window (behind the nail flange), and then that vapor barrier must extend all the way to the base trim where it can then exit.
Thank you for your comment and the valuable input! The window wrap is an important part of the installation process, but your suggestion about adding a house wrap or plastic vapor barrier behind the nail flange is a great tip for extra protection. We appreciate you sharing this additional step with our viewers. Thanks for watching and contributing to the discussion!
