You first need to determine what type of windows you want. Wood, vinyl, fiberglass or aluminum. It's very likely you will have to comply with fairly strict building codes on window construction. Once you have decided on material, you will find that any manuf. that sells windows in your area will have an appropriately rated window.

I would recommend Andersens white 400 series casements with the impact resistant glass. Go to their website and watch a video showing their new products where they show a man hitting the glass with a sledge hammer and can't break through. Contact a Andersen dealer or Home Depot in your area and they can lead the way.
