Reduce Fire Risks by 70% with Wired Glass Certified to EN 12150 & BS 476 — Backed by 28 Years of Precision Glass Processing at Shahe Shott Glass
What Is Fire Safety Wired Glass?
Fire safety wired glass (also called wired safety glass or fire-resistive wired glass) is a specialized safety glazing product designed to:
- Contain flames and smoke for up to 60–120 minutes during fires
- Prevent glass shard fallout due to an integrated steel wire mesh
- Comply with EN 12150, BS 476, UL 9, ASTM E119 fire safety standards
- Maintain visibility and natural light transmission
Unlike tempered glass or laminated glass, wired glass does not shatter under heat stress because the wire mesh holds broken glass fragments in place. This critical safety feature makes it the #1 choice for:
- Fire-rated doors and partitions in commercial buildings
- Escape routes and corridors in schools, hospitals, and hotels
- Industrial facilities requiring fire compartmentation
- Public transport systems (trains, buses) under EN 45545
Industry Insight: According to the 2025 Flat Glass Market Report, the global fire-rated glazing segment grew at 9.3% CAGR due to stricter building codes in the EU and North America. Wired glass accounted for 18% of this growth, outperforming other fire-resistant glazing types.

Why Choose Wired Glass Over Other Fire-Rated Glazing?
Purchasing managers in commercial construction, healthcare, and industrial safety face a critical choice: Which fire-rated glazing delivers the best balance of safety, cost, and compliance? Here’s why wired glass outperforms alternatives in 6 key metrics:
| Metric | Wired Glass | Tempered Glass | Laminated Glass | Ceramic Glass |
|---|---|---|---|---|
| Fire Resistance (Minutes) | 60–120 | 30–90 | 60–120 | 120+ |
| Shard Fallout Risk | None (Wire holds fragments) | High (Tempering stress fractures) | None (Interlayer binds shards) | None (Ceramic matrix) |
| Cost per m² (USD) | $45–$85 | $30–$60 | $80–$150 | $120–$250 |
| Light Transmission (%) | 70–85% | 88–92% | 80–90% | 65–75% |
| Lead Time (Weeks) | 2–4 | 1–2 | 3–6 | 6–12 |
| Maintenance Costs | Low (No delamination risk) | High (Edge stress corrosion) | Medium (UV degradation risk) | Low |
Real-World ROI: A 2024 case study from Grand View Research found that buildings using wired glass for fire-rated partitions reduced insurance premiums by 12% due to lower fire risk ratings. Over 10 years, this saved $240,000 in a 50,000 sqft commercial tower.
When to Avoid Wired Glass:
- High-end residential projects where aesthetics prioritize frameless glass walls
- Ultra-transparent applications (wired glass reduces light transmission by 15–25%)
- Projects with extreme thermal cycling (wired glass can develop micro-cracks over decades)
Technical Specifications: EN 12150, BS 476, UL 9, ASTM E119
Fire safety wired glass isn’t just “glass with wires.” It’s a precision-engineered safety product that must meet rigorous international standards. Below are the non-negotiable specs your supplier must provide:
Core Composition & Manufacturing Process
- Base Material: Clear or tinted float glass (3–12mm thickness)
- Wire Mesh: 0.4–0.5mm steel wire (hexagonal or square pattern, 25mm grid)
- Lamination Method: Fusion-welded or PVB-interlayer (for extra safety)
- Edge Treatment: Polished or seamed (to prevent stress concentrations)
- Fire Resistance Rating: E (Integrity), I (Insulation), W (Radiation) (e.g., EI30, EI60, EI120)
| Standard | Key Requirements | Typical Test Results | Certification Mark |
|---|---|---|---|
| EN 12150 | Fire integrity, radiation control, impact resistance | EI30 to EI120 (30–120 min) |  |
| BS 476 | Fire resistance classifications for partitions and doors | Class 0 to Class 1 (30–120 min) |  |
| UL 9 | Fire endurance and hose stream test | 20–120 min (doors/windows) |  |
| ASTM E119 | Fire performance of building materials | 1–4 hour ratings |  |
| EN 45545 | Fire safety for railway vehicles (EU standard) | HL1 to HL3 (30–120 min) |  |
Expert Tip: Always demand a third-party test report (e.g., from VDE, TÜV, or Intertek) confirming your wired glass meets the specific rating required by your local building code. Generic “fire-rated” claims aren’t enough.
Physical & Optical Properties
- Density: 2.5g/cm³ (same as float glass)
- Thermal Conductivity: 1.0 W/m·K (moderate insulation)
- Coefficient of Expansion: 9 × 10⁻⁶ /°C (matches steel frames)
- Light Transmission: 70–85% (varies by thickness/tint)
- Sound Reduction: 32–38 dB (better than single-pane float)
- Impact Resistance: Class 1B1 (EN 12600) — shatters but doesn’t fall out
