Gun Room with Hardiebacker

[tps7742]

It depends on what the value is you're trying to protect. Hardie is not stopping fire or a thief. I have built two for myself. One with 1" steel plate and a 16" concrete floor with rebar on 8" centers and triple mat. The other with 10" concrete walls double mat rebar. Both are probably overkill but they works as storm shelters too. I also own a few valuables that I dont want to go missing. I own a construction company so I am saving money doing it in house.

This! This is an open forum as we all know.

Not on a tight budget but slab is already poured. So already past the concrete stage. My thought is a room equivalent too a 45-60 min gun safe. Steel door will have a bio-metric key pad or something equivalent. Just more worried about the fire aspect of it all.

You could do 4" 16 gauge metal studs for walls and ceiling with double layer of 5/8" firecode sheetrock with mineral wool insulation. I know someone will barge in and say why 16 ga. and it's because I don't know the room size and span.

There was a thread a few years ago about a gun safe room . Was pretty awesome.

This one is built out out of 8” blocks with 5/8 rebar in every hole filled with 5000psi concrete all the way around. Ceiling is 8” concrete top. With 1/2” rebar 12x12” centers. Slab was already poured for this one but it’s tied in with 5/8 rebar drilled into the slab at an angle and then bent straight into the blocks. Was a little under $10k including vault door. 8’x10’ only wish I’d made it bigger.

Roof top is 6” thick not 8” and it has 5/8” rebar at 12” centers. It was poured all at same time as walls.

Hopefully the slab was designed with the gun room walls in mind.
