Re: Increase security of windows
I find it interesting that burglars always seem to attack the strongest point of entry first: the front door. In many modern houses, especially those with vinyl siding over OSB and sheetrock on the inside, going straight through the wall may be easier! But most burglars are lazy (if they weren't lazy, they wouldn't have to steal) and don't take the time to learn about home construction.
As for a safe room, the walls would need to be reinforced concrete or hardened steel. Bullets and hurricane-driven debris can penetrate just about anything else. If there is a basement or crawl space, the room needs to be supported independently of the rest of the structure so it doesn't collapse with the rest of the house.
Ask TOH had an episode on disaster preparedness a while back that featured a testing lab. They shot a 2x4 at various materials at 20 MPH. It went through a sheet of 7/16" OSB like it wasn't even there. Plywood fared much better.
The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
