I have never seen hurricane proof windows, and I spent a year investigating hurricane damage on the Gulf Coast in 2005, so I have looked at a lot of windows. There are windows which are wind and missile resistant, meaning they are rated for a specific impact, but if a hurricane launches a tree into a window, it is going to break through the window. Anyone who claimed they had hurricane proof anything was misrepresenting their product.
Based on examination of some 200 damaged buildings, I can say that the best way I saw to protect the windows of your home from damage was with sacrificial storm shutters. The best performing ones I saw were steel, specifically rated for wind driven missile impact. The greater the wind speed you want to resist, the more you will pay. At some point, the shutter anchorage to the house becomes critical, since the shutters are useless if they tear off the house. The idea of the shutters is to stop broken glass by absorbing impact from wind driven objects. The shutters are generally destroyed after the storm, but they did their job.
While you are thinking about the windows, the doors are also critical. Steel doors work well, but you either need glass free doors or you need a cover for the glass in the doors, just like the windows. Make sure the door is rated for your design hurricane. The hinges can be a weak point.
And check your rafters, make sure you have hurricane clips on the rafters. Architectural shingles work better than regular shingles, but the key to building survival is that the heavy weight shingles be properly fastened to the plywood sheathing. I can't tell you how many houses I looked at where the shingles peeled off, and water penetrated through the roof, causing catastrophic loss. This was often due to too few nails, improper sheathing, or use of inferior fasteners. By the way, hip roof performed better than gable end roofs, both of which were better than flat roofs.
