We have an old 1920's Tudor with the original small basement windows that basically "pop out" of the frame once you remove the hook lock (like the old hooks you have on a screen door)on each side. The inside window has two sash locks - one on each side, and this window is basically on hinges on the upper portion, so when I open it it opens upward toward the ceiling. Very old fashioned.
I'm looking to replace two of these with something more secure, but I don't want to go with glass block. I still want to be able to open the windows for a fire exit.
Any recommendations on what company to go with that offers security glass?
