Although FEMA does not verify or certify design calculations, we at Tornado Alley Armor keep it a top priority to follow FEMA guidelines. When taking into consideration where your saferoom/storm shelter should be located it is important to consider the foundation. I think I went over 2000 nails in a 8x12ish room.Where is the Best Location for a Safe Room? I was lucky to be able to borrow a friends nailgun. They even spec out how frequently to put nails in for the plywood. Passive ventilation is done per the specs on the plans. It has plate steel hinges and three deadbolts. I think it weighs around 300 lbs and cost around $1300 if memory serves. We bought an ungodly expensive custom door made by a certified storm shelter door manufacturer. Nothing attaches to the floor joists above it (floor of the house main level). The ends of the walls are bolted to the concrete wall also. One wall is the original poured concrete wall, where you hang a ledger to attach the ceiling joists. Ceiling/roof is doubled 2圆's, two layers of 3/4" plywood on the inside, then a layer of 14 (12?) gauge steel inside. Walls have 1 layer of 3/4" plywood on the outside, 2 layers on the inside. Bottom plate is bolted to the concrete floor with expoxied masonry anchors. The new design was considerably heavier than what I built.īasics of the design are doubled up 2x4 stud wall (double studs, double top and bottom plates) spaced to allow solid concrete blocks to be dry stacked between the studs. I built according to the 2014 plans, which they took down. FEMA has plans online for tested designs. I built a storm room in our basement a few years ago. Obviously the big friggin steel door is going to be a dead giveaway to curious neighbors and minimum wage construction crews that you have something well outside the norm going on. Moving in to something like a built in vault, not sure how I'd go about that one right off. From there you could frame out a pretty solid door yourself if you needed. So while an odd request it shouldnt get people wondering how much gold you are storing in there. Underground, solid walls (concrete, rebar for added weight support). Its a bit out of the norm in todays construction but if it raises any eyebrows it will only be because "Hey, my grandma used to have one of those!".Ī root cellar / cold room would generally have all of the characteristics of the other 2 types of rooms outside of the door. You need a cold room to store your vegys and canned goods. A tornado shelter, well that doesnt even need a door!Ī good way to get this pushed past your construction crew with little raising of eye brows is to ask for a root cellar. A secure room has the lock on the inside. Do you want a locking vault to keep a fabulous gun collection? Do you want a small shelter against tornadoes? Do you want a secure room to protect yourself from attackers?Īll are quite similar and yet quite different. I guess it depends on specifically what you mean by "safe room".
