Bullet resistant sheeting test.

[JHC]

I took a trip up to the hills today and thought I'd bring along some scraps of Bullet-Board from work to test out. This stuff is some sort of Kevlar/fiberglass laminate about half an inch thick. We use this stuff to line rooms where one might fear gunfire like courtroom walls, certain rooms in hospitals, etc. I was told it would stand up to a .357 mag, I don't have one of those so I tried a couple of other things.
My .45 wouldn't go through with the +P Corbons ( now I'm not sure of the weight of the bullets since I've had them in a mag for a few years but I think they were 230s) I had which is what I expected but was surprised when my CZ-52 wouldn't either after I had heard all the stories of it's armor penetrating abilities.

My AR and AK rifles easily penetrated the barrier but that was to be expected since the board is primarily designed to resist pistols. I did have to throw a monkeywrench into that logic by using a rifle calibered pistol to defeat the barrier. The AK pistol went right through.

Now before anybody gets the idea that this stuff would be great to line their bunkers with keep in mind that it costs around $350 per 4x8 foot sheet last I heard.

The testing wasn't scientific at all but sure was fun.

Neat. Now of course, here's the part where we ask you where you get bullet board and how much it runs.

[Guns R Tools]

How much does that weight per square foot?

That doesnt seem to bad actually
If I had kids I would certainly do there rooms at bed level

How much does it weigh? Are there any similar materials that can take rifle rounds?

A former co-worker had a family member who used steel plate in his walls...

$350 for 4x8 FEET? That sounds completely reasonable to me.

Can it be installed by some random drywall guy? If the wife and I buy a house, this might be an option.

Heck, sounds like one of those panels ought to be able to do both doors on a vehicle too.

Brilliant !!

One of my pipe dreams is to build a "special" RV using stuff like this, that's why I asked about weight and such. Would doubling up increase it's strength against larger rounds?

I wonder what 357 SIG would do to that board?

357 SIG has superior barrier penetration compared to 9 mm, .40 or .45.

Probably vs larger, but not likely vs faster.

I'd suspect that a "sandwich" would be more efficient than simply two plies of the same stuff. Example, with a sheet of drywall or something in the middle, it could encourage fragmentation on higher velocity rounds, plus give it some travel distance before it hits the next panel.

For that matter, maybe some kind of stainless steel mesh in between might help "cut up" the bullets, thus making 'em less of an "icepick"? Just tossing out ideas there.

A 4x8 sheet weighs about 125 pounds, I'm sure with enough layers it would stop rifle rounds but who knows how many layers it would take? The only multi-sheet test we did was with a Mosin M44 and just slapped 4 layers tight together in the snow, it went through.

$350 was the last I heard and that was a little while back, this stuff comes from Armortex and they have other products as well.

Yes some random Drywall guy can install this stuff, it's usually the newest guy that doesn't know what he's if for. A skill saw is used to cut it, fiber and resin dust get all over you and in you, then self drilling screws attach it to the wall. Drywall is installed over it and it's finishes as usual.
