I've been disappointed in the fire ratings of household safes I have seen in office supply stores. One $400 safe was effective for only one hour at 1500 degrees. I wonder if there is a better way.
I don't need to keep valuables (I have very few of them) in a safe, just important papers (car titles, military records, etc.) so I was just wondering....
My home has a cinder block wall for a foundation. What if, down in the basement, I chiseled out out a small 1' X 1' section that's below grade, dug into the earth some, and then inserted some kind of steel box in the hole, seal it to the wall and attach a fiberglass-insulated door of some kind. Seems like this would be cheaper and much more effective than any commercial job.
