I've been meaning for a long time to do something about the window a/c in my office. Forget about physical security, I didn't even have the side panels attached. I would stick weatherstripping around the gaps and end up with a sticky mess every fall. This year it was time to do something better.
I found this Flickr set, which gave me the idea for how to fasten side panels to a vinyl window and to use PVC pipe to secure the upper sash. Another DIY enthusiast fabricated a piece to make the bottom area more secure, which I considered for a while, but in the end my particular unit and window to fit together well enough.
Additional requirements included improved insulation and a cleaner look.
Step one for peace of mind was moving away from the back mud room roof area, which is just a short hop off the deck, to a side window that hangs off into the mulberry tree abyss. This corner is now accessible thanks to the replacement of the old bookcase with the new streamlined corner stack.
Here are my plans I worked from:
Ok, it looks cleaner than the accordion panels and a 2x4, but I'm not claiming it's pretty! Should I paint it, countersink flat-head screws, or what?
