How to secure a vinyl window to the wall

installationwindows

When installing my vinyl windows should I put a nail into every little hole around the window? It has a flange that has many little holes around it. Also what size nails would you recommend? Finally do I need to secure the window to the inside of the rough opening, as you do with a door?

Yes put a nail into every hole. I would recommend galvanized nails that are 1 to 2 inches in length. If there is nothing behind the flange but plywood, anything over an inch and the nail will just be sticking through the plywood.

I assume you will hit some framing behind the playwood, so a little longer and you will hit that. I looked over my new vinyl windows in my sunroom and there are no attachment points on the inside of the window.

I don't recall doing anything on the inside of the window when installing. The most important point I remember was with the flashing on the outside. Start at the bottom, then the sides, then the top so that water can be properly channelled away. There is a video below in the comments showing an installation. I remember it was pretty straight forward, just made sure the windows are level.
