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.
Your joking right?
Glass vs steel bars that is a tough one. Any type of glass even bullet
resistant which this is probably not, can break. All your really doing is
slowing down the thief. At least with bars on the windows the bad guys can
I will guess your google is busted again
I've seen on TV a kind of burlgar bars that are like a hinged steel gate
mounted inside the house. A cable-linked, pedal-operated mechanism
allows the burglar bars to be unlocked from the inside.
It's not an elegant solution (nor a perfectly safe one -- firefighters
would still have a hard time breaking in to rescue unconscious victims),
but I think an emergency release of some sort is a must for burglar bars.
Nothing including the bars will keep a determined bad guy out.
I would suggest two things the bars have in their favor. First they are
a visual signal that you are taking security serious and may discourage an
attempt and they may (depending on design) allow you to open a window and
still have some security. On the other side, they can keep you inside in
the event of a fire.
