Can anyone recommend window security sympathetic to a 1920s QLDer? We wish to move the kids downstairs, but the windows are far from secure. We have concerns about not having fire escape type grilles. We are getting a quote for crimsafe, and we have crimsafe on other windows upstairs. I am concerned about the potential loss of light - a loss may make our downstairs rooms very dark. A steel company on google looks like a good alternative, with fire escape options available, but I'm looking for ideas/photos/company recommendations. Thanks!
