X-Flex wallpaper won't make your walls aesthetically pleasing, just safe from collapsing from lethal force. This startlingly resilient covering is designed to reinforce buildings against man-made blasts, flying shrapnel and destabilizing natural disasters.

Now if only they could make some to cover the windows.
