Bulletproof Glass — Type 79 SMG Resistant (GA165 / ≈ EN1063 BR3-4)
Lumiglas bulletproof glass FDCL-3B-30: Type 79 7.62mm submachine gun resistant. GA165-2016 certified, 30 mm composite, multi-layer PC-glass-TPU.
Description
Bulletproof glass Level 3 is a multi-layer ballistic composite glass engineered to defeat submachine gun fire, including the Type 79 7.62mm service SMG, at point-blank to short range. Specifically, the 30 mm composite stack consists of alternating tempered glass and polycarbonate (PC) layers bonded with TPU interlayers, laminated under controlled heat and pressure. Lumiglas certifies the assembly to GA165-2016 Level 3 — the Chinese national bulletproof glass standard issued by the Ministry of Public Security. Therefore, the glass stops a Type 79 7.62mm steel-core bullet traveling at 480–515 m/s with a kinetic energy of approximately 755 J.
Because the GA165-2016 test protocol for Level 3 uses a higher-velocity automatic weapon round than the EN1063 BR3 reference, FDCL-3B-30 glass meets the kinetic energy threshold of EN1063 BR3 (720 J). Moreover, the multi-layer PC-glass-TPU construction provides equivalent protection against the burst-fire pattern typical of submachine gun engagement. However, EN1063 uses different cartridge types and verification protocols. As a result, where formal EN1063, UL752 or NIJ certification is required, Lumiglas arranges supplementary testing on customer request using the corresponding standard ammunition.

Composite layer construction
Lumiglas Level 3 bulletproof composite glass uses a 7-layer stack that alternates tempered glass and polycarbonate, bonded with TPU interlayers. Specifically, the strike face is glass, which shatters and dissipates the bullet’s initial energy. The TPU interlayer absorbs fragments. The PC layer deforms plastically and arrests the bullet. Moreover, the cycle repeats through multiple layers for high-velocity automatic fire. The final layer facing the protected side is polycarbonate, which prevents back-face spall (glass fragments flying toward the protected person).
| Layer # | Material | Function |
|---|---|---|
| 1 — Strike face | 8 mm tempered glass | Initial bullet shatter |
| 2 | 1.27 mm TPU interlayer | Fragment containment |
| 3 | 5 mm polycarbonate (PC) | First ballistic deformation layer |
| 4 | 1.27 mm TPU interlayer | Interlaminar bonding |
| 5 | 8 mm tempered glass | Secondary energy dissipation |
| 6 | 1.27 mm TPU interlayer | Spall absorption |
| 7 — Protected face | 5 mm polycarbonate (PC) | Final ballistic stop, spall prevention |
⚠ Installation orientation: The glass face MUST face the threat side (outside / strike face). The polycarbonate face must face the protected side. Reversed installation will fail at the first hit.

Typical applications
Level 3 bulletproof glass suits applications where the credible threat includes submachine gun rounds typical of organised armed groups, special-unit weapons or military security teams. Specifically, the most common installations include:
- Embassies
- Government Vehicles
- Cash-in-Transit
- Police Command Vehicles
- Border Posts
- Steel Plant Control Rooms
- Cash-in-transit and armored cars — Level 3 is the de facto minimum for cash transport vehicles where the operational threat includes organised armed robbery using SMG. Therefore, fleet operators worldwide specify Level 3 minimum for security vehicle window glazing.
- Embassy and consulate ground-floor glazing — Diplomatic facilities in high-threat regions specify Level 3 minimum for public-access areas. Moreover, the multi-layer construction provides reliable protection against burst-fire engagement.
- Police command and tactical response vehicles — Up-armored police vehicles for SWAT and tactical deployment, including command posts and prisoner transport.
- Industrial control room glazing — Steel smelting and chemical plant central control rooms where insider or external sabotage with personal firearms is a credible threat.
- Border post and government convoy escort glazing — Fixed border infrastructure and escort vehicles operating in high-threat corridor regions.
Engineering and specification notes
Why kinetic energy matters more than caliber
Two cartridges of the same caliber can have very different penetration capability — what matters is kinetic energy at impact, calculated as E = ½ × m × v². For example, a 7.62 mm pistol round and a 7.62 mm rifle round share the same diameter but the rifle round delivers approximately 4 times the kinetic energy because the velocity is higher. Therefore, specification by caliber alone is insufficient. Lumiglas product levels are matched to specific cartridge + velocity combinations as defined by GA165-2016.
Multi-hit performance for automatic fire
Submachine guns deliver burst fire — multiple rounds in rapid succession to a small target area. The Level 3 composite stack is designed to absorb multi-hit engagement without sequential layer failure. Specifically, the dual glass + dual PC construction distributes impact load across the laminate, so a second round arriving 50 ms after the first does not penetrate even if both hits cluster within a 100 mm radius. However, sustained fire concentrated at a single point will eventually defeat any ballistic glass — for high-threat applications, consider Level 4 upgrade.
Frame and mounting considerations
Bulletproof glass performance depends on proper frame mounting as much as on the glass itself. The frame must hold the glass on all four edges with adequate bite depth (typically 30 mm minimum for Level 3). Moreover, the frame material must transfer impact load to the surrounding structure without flexing. Lumiglas provides frame specification recommendations on request — submit your installation drawing for project-specific engineering review.
Weight and structural load
At 60 kg/m², a 1 m² panel of FDCL-3B-30 weighs approximately 60 kg. Therefore, vehicle window retrofits require chassis assessment — particularly for B-pillar and roof load paths — before specification. For static installations, anchor bolt count and surrounding wall capacity must be reviewed.

Frequently asked questions
Standard and certification
What is GA165-2016 Level 3?
GA165-2016 is the Chinese national bulletproof glass standard, issued by the Ministry of Public Security. Level 3 specifies resistance to Type 79 7.62mm submachine gun with steel-core bullet, 5.56–5.69 g at 480–515 m/s (~755 J kinetic energy). To pass certification, the glass must stop the bullet with no penetration and no back-face spall fragments.
How does GA165 Level 3 compare to EN1063 BR3?
The kinetic energy at impact for GA165 Level 3 is 755 J, which meets the EN1063 BR3 reference kinetic energy of 720 J. Therefore, FDCL-3B-30 glass meets or exceeds the EN1063 BR3 threshold. However, EN1063 certification requires testing with EN-specified cartridges. As a result, formal EN1063 certification testing is available on customer request.
Can you provide EN1063 / UL752 / NIJ certification?
Yes. Lumiglas arranges supplementary ballistic testing under EN1063 (Europe), UL752 (USA) or NIJ 0108.01 (USA) standards using the corresponding standard ammunition. The supplementary testing typically takes 4–6 weeks from order and is charged at cost. Submit your project specification and preferred standard when enquiring.
Construction and performance
Will Level 3 glass stop multiple hits from automatic fire?
Yes — within reason. The Level 3 composite is engineered for multi-hit engagement typical of submachine gun burst fire. Specifically, the dual glass + dual PC construction distributes impact load so that a second round 50 ms after the first does not penetrate even if both hits cluster within a 100 mm radius. However, sustained automatic fire concentrated on a single point can eventually defeat any ballistic glass. For high-threat applications expecting sustained engagement, consider Level 4 upgrade.
Why is the bulletproof glass composite, not solid glass?
Solid glass cannot stop high-energy projectiles — it simply shatters and the bullet continues through. Composite bulletproof glass uses alternating layers of tempered glass (which shatters and dissipates initial bullet energy), TPU interlayer (which absorbs glass fragments and slows the bullet) and polycarbonate (which deforms plastically and captures the bullet). Therefore, each material contributes a different physical mechanism. Moreover, the polycarbonate face on the protected side prevents back-face spall.
Which side faces the threat?
The glass face (marked at the factory) must face the threat side — outside, exterior or strike face. The polycarbonate face must face the protected side — interior, secure room or operator position. Reversed installation will fail at the first impact because the polycarbonate cannot shatter the bullet on initial contact. Confirm orientation with the strike-face label before final mounting.
Sizing and ordering
What sizes can Lumiglas produce?
Standard panel sizes run up to 2400 × 1600 mm. Smaller panels for vehicle windows, control room glazing or vault doors are produced from the same composite stack. Custom shapes — including curved, cut-corner and small viewing apertures — are available on request. Provide a dimensioned drawing with the required frame mounting detail for a project-specific quote.
What is the lead time?
Standard Level 3 panels in stock dimensions ship in 2–3 weeks. Custom sizes or quantities above standard production run typically require 4–6 weeks. For projects requiring supplementary EN1063 / UL752 / NIJ testing, add 4–6 weeks for the testing protocol. Contact us with your project schedule for confirmed delivery dates.
