02 – Product Definition (What Is It?)
H2: What Is Low-Iron Acoustic Glass?
Low-Iron Acoustic Glass is a high-transparency acoustic safety glass manufactured from ultra-clear (low-iron) float glass, bonded with an acoustic PVB interlayer—or assembled into an insulating glass unit (IGU)—to deliver both exceptional sound control and near-colorless visual clarity. Standard clear glass contains iron oxides that impart a greenish tint, especially visible at the edges and in thicker builds. By reducing iron content (Fe₂O₃ ≤ 0.015%), low-iron glass achieves superior light transmittance and truer color rendering, making it the preferred choice for premium office pods, executive meeting spaces, and high-end architectural glazing where appearance matters as much as acoustics.

03 – Glass Structure
H2: Glass Structure & Composition
Acoustic Laminated Build (most common):
6 mm Low-Iron Tempered Glass
↓
Acoustic PVB Interlayer (0.76 / 1.14 / 1.52 mm)
↓
6 mm Low-Iron Tempered Glass
Acoustic Insulated Build (for higher STC + thermal):
6 mm Low-Iron Tempered Glass
↓
16 mm Argon Cavity
↓
6 mm Low-Iron Tempered Glass
Key Structural Elements:
- Glass Type: Ultra-clear low-iron float (Fe₂O₃ ≤ 0.015%); fully tempered or heat-strengthened
- Interlayer: Acoustic PVB (standard) / Low-Iron (ultra-clear) PVB on request / SGP optional
- Interlayer Thickness: 0.76 mm / 1.14 mm / 1.52 mm
- Overall Thickness: ~10 mm to ~22 mm (laminated); ~24–32 mm (IGU)
- Safety: Meets EN 14449 / ANSI Z97.1; post-breakage fragments remain bonded to PVB

*Acoustic performance is indicative and depends on complete system design, including frame, sealing, and installation. Test reports available upon request. |
05 – Acoustic Performance
H2: Acoustic Performance
- Sound Transmission Class (STC): 39 – 47 (depending on configuration)
- Weighted Sound Reduction Index (Rw): Up to 45 dB
- Frequency Range: Optimized for 500 Hz – 4000 Hz (speech frequencies)
- Test Standards: ASTM E90, EN ISO 10140, ISO 717-1

06 – Visual & Optical Performance（本页差异化模块）
H2: Visual & Optical Performance — The Low-Iron Advantage
| Parameter | Low-Iron Acoustic Glass | Standard Clear Glass |
|---|
| Iron Oxide (Fe₂O₃) | ≤ 0.015% | ~0.08–0.12% |
| Visible Light Transmittance (VLT) | 88% – 91% | 80% – 85% |
| Haze | ≤ 0.5% | ≤ 1.0% |
| Edge Color | Near-colorless / neutral | Visible green tint |
| Color Rendering | True-to-life (high CRI feel) | Slightly green-shifted |
- Ultra-Clear Aesthetics: Near-colorless appearance, especially valued in thin-profile premium pods where edge greening detracts from brand image.
- Premium Brand Alignment: Preferred by designer-led pod manufacturers positioning on quality, transparency, and material honesty.
- Optional Ultra-Clear PVB: Pair low-iron glass with low-iron (optically clear) PVB interlayer to eliminate any residual yellowness/haze in the bond line.
07 – Safety & Thermal
H2: Safety & Thermal Performance
- Impact Safety: Classified as Class A / Class B (EN 12600), ANSI Z97.1 Category II
- Post-Breakage: Glass fragments remain bonded to PVB interlayer—no shattering or fall-out
- Tempered: Heat-treated for 4–5× strength vs. annealed glass; optional heat soak (EN 14179-1)
- UV Blocking: Acoustic PVB blocks up to 99% of harmful UV radiation
- Thermal (IGU build): U-value 1.2–2.8 W/m²K (argon-filled IGU); optional Low-E coating → see Low-E Acoustic Glass page
