Overview

Laminated safety glass for balustrades is a critical architectural glazing solution designed to provide maximum safety, structural performance, and aesthetic transparency. Manufactured by bonding two or more layers of glass with high-performance interlayers such as PVB (Polyvinyl Butyral), SGP (SentryGlas® Plus), or EVA, the system ensures that the glass remains intact even after breakage, preventing fall hazards and maintaining barrier integrity.

Specifically engineered for guardrails, railings, and fall-protection systems, laminated glass is widely used in both residential and commercial buildings where safety compliance and design excellence are paramount.

Glass Build-Up & Configuration

Glass Types:

• Fully Tempered (Toughened) Glass
• Heat Strengthened Glass

Lamination Options:

• Double Laminated (e.g., 8+8 mm, 10+10 mm, 12+12 mm)
• Multi-layer Laminates for higher load requirements

Interlayer Types:

• PVB: Standard safety and acoustic performance
• SGP: High structural stiffness and load-bearing capability

Key Performance Features

• Post-Breakage Safety: Glass fragments remain bonded to interlayer, maintaining barrier integrity
• High Load Resistance: Designed to withstand line loads and impact forces as per international standards
• Structural Capability: SGP interlayers enable glass to act as a structural element
• Impact Resistance: Suitable for human impact and safety-critical applications
• UV Protection: Reduces UV transmission, protecting interiors
• Acoustic Damping: Improves sound insulation in occupied spaces
