Hi All,

I've got to replace some windows in some concrete-block houses. These
houses are in a low-rent area so the window design needs to be robust.

What's a good value today in a vinyl window?

Robust in what regard? Rough usage by the occupants or security to prevent
break-ins?

Very few windows, by themselves, are going to prevent break-ins. If that's
what you mean by "robust" then consider window bars, either interior so the
tenants can operate them...

Or exterior...

If you want something that will hold up to any type of rough usage from the
tenants then you are probably going to spend more than you like. You will
be looking for metal pins instead of plastic for the sliders and other
"upgraded" features.

I suggest you look around your area for a place that services contractors,
such as Norandex/Reynolds, and give them your requirements.
