Historically if one had wood storm windows they also had wood window screens. Wood screen windows are just like wood storm windows except there would be screens instead of glass.
In my opinion this is an unnecessary luxury that takes up valuable storage space and detracts from curb appeal by hiding your windows.
Adjustable Window Screens are my recommendation.
Horizontal sliding screen frames are adjusted to fit perfectly to any width window.
I have a variety of sizes on hand – some that are larger and smaller in height depending on how much outside air you want.
Adjustable louvers are also available for attic ventilation.
Remember to paint the frames to match your window sash color.
Here is a link to adjustable window screens .
They are historically correct, easy to use and store, and are very inexpensive. They can be purchased at real hardware stores or online here .
Another historically correct option which I use mostly are lace curtains. They provide the same purpose as screens. Bugs cannot enter.
Whatever you choose as a screen, do NOT get a full window screen. You will be hiding the beauty of your window!
In the above image the window on the left is bare and the window on the right has a full window screen. Notice how the screen changes the appearance of the window. I recommend using only half screens or the adjustable screens discussed.
