I am replacing windows that currently have metal bars on them to prevent break-ins (necessary in my neighborhood). A window guy that is giving me an estimate on the job suggested that if I use Armor Glass, I will not need the bars.
1) Is this true? Is Armor glass as safe as metal bars? 2) He is asking an additional $140 per window (2 windows are 24 X 36, the other two are 66 X 34). Is this a reasonable cost? 3) How will the Armor glass affect the Visible Tranmittance (the amount of light coming through). Most of the windows that I have been looking at have a VT of between .5 and .6. Is Armor glass significantly lower?Thanks in advance for any help.
