As we talked about in our closing submit, the extraordinarily environment friendly, applicable .223 has shortly flip into among the many fashionable rifle cartridges in America–which furthermore makes it a rising concern for anybody eager about bullet proof safety. Sadly, the commonest consumer-grade bullet proof dwelling dwelling home windows merely can’t match the penetrating vitality of the .223.

A Momentary Contemplate on the .223

The .223 is the patron model of the army’s 5.56 ammunition utilized in M16 assault rifles (which could be in flip based totally completely on the Colt AR-15 semi-automatic rifle, and have flip into the mannequin for contemporary sporting rifles). The projectile of the .223 has dimensions similar to that of the frequent .22 rifle cartridge (which are typically used for educating, purpose apply, “plinking,” and searching very small sport like squirrels, rabbits, and pest rodents). Each are confirmed contained in the picture beneath (with the a .22LR on the left and the .223 on the precise).

What you’ll instantly keep in mind is that though the bullets (that’s the perfect of the cartridge, the precise projectile) have related dimensions, the .223 is clearly far more aerodynamic (and is perhaps a bit heavier: .22s normally vary between two and three grams, whereas .223s may be as heavy as 5 grams).

The essential factor variations is contained in the load: The hundreds better casing of the .223 permits for a lot further gunpowder to propel the bullet. Consequently, a .223 bullet travels as lots as thrice sooner than the .22 bullet–it’s one amongst many quickest bullets in the marketplace to most individuals–and strikes almost ten occasions further sturdy.

The mixture of a small, aerodynamic projectile shifting terribly quick makes the .223 considerably arduous to cease with customary bullet proof dwelling dwelling home windows.

.223 Bullet Resistant Dwelling dwelling home windows

Most bullet resistant dwelling dwelling home windows in the intervening time put in in liquor retailers and banks use monolithic acrylic. At spherical 1.25 inches, safe acrylic will merely cease various rounds from 9mm, .357, or .44 Magnum pistols. These rounds (confirmed inside the image beneath) are most steadily “semi wadcutters”: Snub-nosed projectiles designed to pancake, and thus efficiently change their momentum to their purpose for max stopping vitality at shut vary.

Acrylic bullet resistant glass takes advantage of this design: the bullet pancakes on the arduous flooring of the acrylic, and its momentum is wolfed up shortly because of it smashes a handful of chips off the bottom.

Nonetheless the physics of a .223 is considerably fully fully totally different kind that of a semi wadcutter; the .223 is slim, sharp, and shifting quick–it’s designed to pop appropriate through a barrier, even an acrylic bullet proof window.

Defending within the route of the .223 requires a very fully fully totally different method. Not solely should the ballistic glass be thicker–a minimal of 1.625-inches thick, if not 1.75–it furthermore must be of a very fully fully totally different composition. The one bullet resistant glass that’s going to cease a .223 is glass-clad polycarbonate. This laminated ballistic transparency is made by stacking layers of tempered glass and polycarbonate–a thermoplastic similar to acrylic, nonetheless softer and extra pliable–interleaved with skinny layers of epoxy.
When a .223 strikes a window manufactured from glass-clad polycarbonate, the outer flooring of tempered glass forces the projectile to partially pancake, spoiling its aerodynamic design. That tempered glass then shatters, and the inside layers of epoxy and polycarbonate flex like a backstop. On account of this provides is softer and denser than bullet resistant glass or acrylic, it normally swallows the bullet up and holds it. Whereas an acrylic-based bullet resistant window is unlikely to cease even a single .223, a rated Stage 7 system utilizing glass-clad polycarbonate ballistic glass will merely catch a burst of 5 or additional of those bullets.
Nonetheless a bullet resistant window isn’t solely a hunk of glass-clad polycarbonate. With a purpose to truly maintain individuals protected, these dwelling dwelling home windows must be mounted in true ballistic framings, not 14 gauge metallic–which the .223 spherical was designed to penetrate–or the fiberglass “packed” frames some bullet proof firms use to carry down prices. Bullet proofing specialists like Total Safety Selections vp Jim Richards at all times advise that their high-level bullet resistant dwelling dwelling home windows be mounted in a specialised UL-rated bullet proof aluminum physique backed with internally built-in strips of ballistic fiberglass.

Costly James,
I’ve nowadays bought uncooked land to assemble my retreat. Quickly I’m going to start growing a house, and must equip it with dwelling dwelling home windows which may resist small arms fireplace. I can buy Lexan in half of″ thickness, and my query is, will I would really like two objects of glazing in every window, or three (or additional)? I don’t suppose it possibly that I will possibly be shot at with one factor better that .50 caliber. Your ideas on the matter are most welcome. Thanks, – Zoomer

JWR Replies: To start out out, I’ve to warn readers that acrylic Plexiglas and polycarbonate Lexan are considerably fully fully totally different supplies. Lexan is versatile, whereas Plexiglas is fairly brittle. One different versatile clear polycarbonate plastics embrace Armormax, Cyrolon, Hygard, Lexgard, Makroclear, Makrolon, and Tuffak. So solely use one amongst these for ballistic safety capabilities, not Plexiglas!

Your intent to make the most of various laminations of half of″ thick Lexan is not with out precedent. Nonetheless its sounds simpler than it actually is, in good software program program. One sheet (of half of″ thickness) Lexan will cease single hits from a .22 Extended Rifle (LR) rimfire, nonetheless not repeated hits within the occasion that they are well-aimed. Two thicknesses will cease 9mm, nonetheless they gained’t cease any bullets at elevated velocity. Sadly, it’s going to take bigger than 3″ of merely Lexan to cease most rifle bullets, and possibly extra of that to cease .30 caliber steel-cored AP bullets from a 7.62mm NATO, .30-06, or 7.62x54r. And I’d assume that stopping .50 BMG AP or API would require bigger than foot of thickness of merely Lexan, nonetheless I haven’t been capable of finding an unclassified present on this. For comparability: the Springfield .30-06 produces a muzzle energies as lots as 3,000 foot-pounds, whereas .50 BMG ball produces as lots as 15,000 foot-pounds! (An unclassified commerce white paper Sierracin/Sylmar Agency is fairly instructive. Detailed ballistic safety specs for army armored glass developed by the US and UK army are categorized.)

The armored glass utilized in numerous present lightly-armored autos such because of the up-armored M1114 HMMWV are as lots as 3.5″ thick (relying on armoring interval), and use proprietary sandwiches of clear polycarbonate plastics and laminated glass. Lighter-weight armored glass made for limousines are way more distinctive (and expensive), nonetheless are nonetheless fairly thick and heavy.) One in every of many finest is Worldwide Safety Glazing’s Secur-Tem + Poly, which has been examined to NIJ Stage IV safety within the route of single .30-06 hits. Nonetheless even this is nonetheless 2.11 inches thick, and it weighs 24.38 kilos per sq. foot. The cost per sq. foot for this provides is fairly excessive.

Mainly primarily probably the most environment nice bullet resistant dwelling dwelling home windows are made by bonding alternating layers of Lexan and laminated glass. Observe that in case you make your personal, that the inner-most layer should at all times be Lexan fairly than glass, to forestall glass fragment spalling. (Simply because a bullet is stopped, doesn’t defend you from getting splattered with fragments, because of the inner-most layer flexes with a hypersonic shock wave.) It is notable that the majority fashionable armored autos have a spall liner.

So, say that you just simply should assemble a home with “.50 caliber bullet proof dwelling dwelling home windows”? Sadly, the price of even .30 AP safety would greater than doubtless be prohibitive for establishing any residential dwelling dwelling home windows better that 12″ x 12″, and even then their transparency would undoubtedly endure. With increasingly further laminations, a window turns into progressively additional opaque–that is, translucent fairly than clear.

Lastly, you may take into accounts that the window physique that you just simply use must be giant, very stout, and truly firmly linked. In one other case, your window laminate will come out with the have an effect on of the primary shot, leaving the opening unprotected. Dwelling dwelling home windows with slim or in one other case unsubstantial frames would even be weak to assault by sledgehammers. A wedge customary cross-section (achieved by making the outer layers progressively better flooring home sheets, and a tapered window physique, to match) is the perfect method to defend within the route of such assaults.

Reader George S. wrote so as in order so as to add: The Schott Glass/ GEMTRON Vincennes, Inidiana glass manufacturing line has been shut down, nonetheless their manufacturing of laminate glass direct imaginative and prescient panels for the recent-generation Oshkosh army MRAP armored autos is nonetheless in operation.
