Must-Read for Curtain Walls & Railings! How to Choose PVB/EVA/SGP Laminated Glass?
2026-02-21
As modern architecture pursues safety, aesthetics and functionality, laminated glass has become a core material for curtain walls, railings and high-end interior design.
Faced with PVB, EVA, SGP interlayers, most projects struggle to choose the right one. Here’s clear, practical guidance to avoid mistakes.
🔹 PVB Laminated Glass | Reliable & All‑Round Standard Choice
The most widely used interlayer for buildings, ideal for curtain walls, windows, doors, balcony railings and stair handrails.
✅ Advantages: Strong impact resistance | Excellent sound insulation | High light transmittance + UV blocking | Mature application & cost-effective
⚠️ Limitations: Moderate water resistance; cautious use in highly humid environments
Best for: Most residential and commercial projects – balanced performance you can trust.
🔹 EVA Laminated Glass | Ideal for Decorative & Artistic Design
Great for decorative and customized applications.
✅ Advantages: Excellent flowability for silk-screen printing, fabric interlayer, metal mesh | Suitable for curved and shaped glass | Good water resistance
⚠️ Limitations: Moderate UV resistance; may yellow under long-term direct sunlight
Best for: Hotel interiors, office partitions, art glass and furniture glass.
🔹 SGP Laminated Glass | Top Choice for High-Safety Structures
Ionomer interlayer representing premium structural safety performance.
Compared with PVB at the same thickness:
- Load-bearing capacity: ≈ 2x higher
- Bending deformation: only 1/4
- Tear strength: ≈ 5x higher
✅ Advantages: Ultra-high structural strength | Excellent tear resistance | Outstanding UV resistance & anti-yellowing
Best for: Bulletproof glass, explosion-proof glass, structural load-bearing glass, high-rise buildings and large public constructions.
