How can I make windows lightproof?+?
Question:I need to black out the windows in our school hall
Answers:
I needed a temporary, cheap option for the months I was working night shift. I cut a piece of cardboard to fit my window, spray painted the outside-facing side white (like the lining of drapes) and the inside-facing side the same color as my drapes. I nailed the cardboard to the window frame, and you couldn't even tell by looking at the window what I had done. It was completely black in the room while I was trying to sleep, and easy to remove when I went back to morning shift!
Brick wall or black paint ?
Temporarily, you can tape sheets of black butcher paper over the window panes. Cardboard, tarp material, or heavy plastic sheeting will work too.
For a more permanent solution, you'll need to apply two or more coats of dark paint.
Hi,
The permanent thing would be to paint them black but somehow I don't think that is what you want.
Two other options buy or get the woodworking class to make shutters.
The second option is to by black out curtains and a rail or blackout roller blinds.

blackout curtains. they are often actually white so will not make the room dark when they are open.
Try aluminum foil. It will also keep the heat out.
black paint
Place something in front it so the light doesn't come in, at a school you must have all sorts of things you can use.
