When we lived upstairs, we knew that we would only be there for a year or two. So when we needed screens I used press on velcro to hang the screens. Downstairs, Renata (the former tenant) had just stapled screen into the window. But now we are downstairs and hopefully not about to move anytime soon so I decided to make screens using removable wooden frames.
Screens stapled to the window. Not a good idea if you want to paint the window frame.
Wood for the frames
Cut to measure for each window
The frame put together before painting
Painted and ready for the screen to be stretched.
The final product.
All in all I spent 100 Euros for wood, screen, paint, screws et al. That made 6 screens and with the exchange rate probably about $20 a screen. But they are sturdy, have already withstood some hail with no damage and removable. Costantino even gave them a nod of approval.
