Hi I am David Belch and I'm here with Expert Village today to show you how to install windows. What I am going to do now is place the window in the opening. This is the right replacement. Since I have a top stop I just want to hold my window in, it is a sloping ceil, just set the window on the outer edge. What
that does it lowers my window and allows my window to drop in, then I push my bottom in, and now the window is held by the top stop and I can let go of it. Then what I do next is to take shim boards all the way to the far corner. If you don't go to the far corner what is going to happen is that it
is going to bow your ceil and that is a no no. I go to the far side, jack my window up and what this does is it brings my window all the way solid to the top. Now I can insulate my window.
