Thread: Safe room specifications/designs

Plain wood or concrete aren't going to stop a determined attack, but you can slow them down. The main illegal methods of entry are likely to be chainsaw, grinder, hammer... If I was doing this, I'd get kevlar / aramid fabric and sandwich it between layers. Even fishing braid set or glued into the inner walls will probably help slow any fast-spinning cutting thing down. Grinders and chainsaws have a much harder time dealing with fabric than with steel or concrete. Hammers are quite ineffective against steel, so at least a few bits of that if I could work it into the design. I'd also make it soundproof so I can lock myself away from the world if I wanted to! Good luck - and let's hope whatever you build never gets put to the test.
