Product Highlights
1. What Is Low-E Laminated Glass?
- Low-E Coating: An invisible metallic oxide coating that reflects heat while allowing natural light to pass through—improving energy efficiency.
- Laminated Glass: Two or more glass panes permanently bonded together with a PVB, SGP, or EVA interlayer—providing safety, security, and UV protection.
2. How It Works
| Component | Function |
|---|---|
| Low-E Coating | Reflects interior heat back inside during winter; blocks solar heat gain during summer |
| PVB / SGP Interlayer | Bonds glass panes together; holds fragments in place upon impact; blocks 99% of UV radiation |
| Multiple Glass Panes | Provides structural strength and thermal mass |
| Tempered Glass Option | Adds impact resistance and safety characteristics |
Performance Benefits
| Benefit | Description |
|---|---|
| Energy Efficiency | Low-E coating reduces heat transfer—lowers heating and cooling costs by 20–40% compared to standard laminated glass |
| Safety & Security | Interlayer holds glass fragments in place upon impact—prevents dangerous shattering and resists forced entry |
| UV Protection | Blocks 99% of harmful UV radiation—prevents fading of furniture, flooring, artwork, and textiles |
| Acoustic Insulation | PVB interlayer dampens sound vibrations—provides 28–38 dB noise reduction |
| Structural Integrity | Maintains functionality even when broken—ideal for overhead glazing, balustrades, and facades |
| Aesthetic Appeal | Clear, unobstructed view with subtle energy-saving performance |
Low-E Coating Types
| Coating Type | Application Method | Characteristics | Best Use |
|---|---|---|---|
| Soft-Coat (Sputtered) | Applied in vacuum chamber after glass forming | Superior thermal performance (lowest U-value); must be protected within laminated or insulated units | High-performance facades, cold climates, green buildings |
| Hard-Coat (Pyrolytic) | Applied during glass manufacturing | Durable; can be used as exterior surface; moderate thermal performance | Warm climates, single-pane laminated applications, skylights |
Laminated Glass Configurations with Low-E
| Configuration | Coating Position | Interlayer | Typical U-Value (W/m²K) | Typical SHGC | VLT | Best Application |
|---|---|---|---|---|---|---|
| 2-Layer: Low-E + Clear | Surface #2 (on interior pane) | 0.76mm PVB | 1.2 – 1.6 | 0.55 – 0.65 | 65 – 75% | Balustrades, railings, interior applications |
| 2-Layer: Tempered Low-E + Tempered Clear | Surface #2 | 1.52mm PVB | 1.2 – 1.6 | 0.55 – 0.65 | 65 – 75% | Safety glazing, doors, storefronts |
| 2-Layer: Low-E + Low-E | Surface #2 & #3 | 0.76mm PVB | 1.0 – 1.3 | 0.45 – 0.55 | 60 – 70% | High-performance facades, cold climates |
| 3-Layer: Low-E + Clear + Clear | Surface #2 | 0.76mm + 0.76mm PVB | 1.1 – 1.5 | 0.50 – 0.60 | 60 – 70% | Security glazing, acoustic applications |
| Low-E + SGP Laminated | Surface #2 | 1.52mm SGP | 1.2 – 1.6 | 0.55 – 0.65 | 65 – 75% | Structural glazing, hurricane-resistant, glass floors |
| Low-E + Acoustic PVB | Surface #2 | 0.76mm Acoustic PVB | 1.2 – 1.6 | 0.55 – 0.65 | 65 – 75% | Noise-sensitive environments, urban buildings |
Coating Position Considerations
| Position | Description | Application |
|---|---|---|
| Surface #1 | Exterior-facing surface of the outer pane | Hard-coat Low-E for exterior exposure; solar control in warm climates |
| Surface #2 | Interior-facing surface of the outer pane (most common) | Soft-coat Low-E protected within laminated assembly; optimal thermal performance |
| Surface #3 | Exterior-facing surface of the inner pane | Soft-coat Low-E for additional insulation; used in triple-layer laminates |
| Surface #4 | Interior-facing surface of the inner pane | Hard-coat Low-E for interior applications |
Interlayer Options for Low-E Laminated Glass
| Interlayer Type | Key Characteristics | Best Applications |
|---|---|---|
| Standard PVB | Excellent adhesion, impact resistance, 99% UV block | General safety glazing, balustrades, railings |
| Acoustic PVB | Enhanced sound dampening properties; 38–42 dB reduction | Hotels, hospitals, airports, urban buildings |
| SGP (SentryGlas®) | Superior strength (5x stronger than PVB); edge stability; post-breakage performance | Structural glazing, skylights, hurricane-resistant facades, glass floors |
| EVA | Better moisture resistance; suitable for outdoor exposed edges | Exterior applications, decorative laminated glass |
Applications
| Sector | Common Uses |
|---|---|
| Architectural | Curtain walls, skylights, canopies, glass facades, atriums |
| Residential | Windows, sliding doors, patio doors, balustrades, pool fencing |
| Commercial | Storefronts, office partitions, reception areas, conference room glazing |
| Security | Banks, government buildings, embassies, retail displays |
| Acoustic | Airports, hotels, hospitals, recording studios, urban residential |
| Transportation | Train windows, bus windows, marine glazing |
