Laminated Glass Partitions

Safety Glass Partition Walls with Post-Breakage Retention – Engineered for Occupant Protection & Long-Term Reliability

Laminated glass partitions​ are interior glass wall systems that use two or more glass plies bonded together with a polyvinyl butyral (PVB) or SentryGlas® (SGP) interlayer. Unlike monolithic tempered glass, laminated glass remains intact when broken​ – the interlayer holds shattered fragments in place, preventing dangerous falling glass and maintaining a barrier even after impact.

For procurement managers, safety consultants, and glazing contractors supplying corporate offices, schools, healthcare facilities, public buildings, and any environment where occupant safety is paramount, laminated glass partitions represent the highest standard of interior glazing safety – offering post-breakage retention, enhanced impact resistance, and optional acoustic performance​ that monolithic glass cannot provide.

💡 Why laminated matters for partitions:​ Building codes increasingly require safety glazing for interior partitions in specific locations – particularly doors, sideline panels, and areas within 500mm of circulation paths. Laminated glass not only meets these code requirements but provides an additional layer of protection: even if the glass is struck with sufficient force to break, the interlayer prevents dangerous shards from falling into occupied spaces. For glass suppliers, laminated partition glass commands a 25–40% premium over monolithic tempered due to the additional processing, materials, and quality assurance required.

1. Laminated Glass Partition Applications

Laminated glass partitions are specified wherever post-breakage safety, enhanced impact resistance, or acoustic performance is required.

2. Laminated Partition Systems

Laminated glass can be incorporated into virtually any partition system. The choice of system affects the glass build-up recommendation.

2.1 Framed Laminated Partition

• Description:​ Laminated glass panels set within aluminium or steel perimeter frames
• Glass build-up:​ 8T + 1.52PVB + 8T (17.52mm) – standard
• Best for:​ Standard office partitions, cost-effective safety solution
• Key benefit:​ Frame provides additional edge protection; PVB interlayer sufficient

2.2 Frameless Laminated Partition

• Description:​ Laminated glass panels joined edge-to-edge with minimal hardware
• Glass build-up:​ 10T + 1.52SGP + 10T (21.52mm) – recommended
• Best for:​ Premium frameless installations requiring post-breakage safety
• Key benefit:​ SGP interlayer provides superior residual strength after breakage

2.3 Floor-to-Ceiling Laminated Partition

• Description:​ Full-height laminated glass panels from floor to structural ceiling
• Glass build-up:​ 8T + 1.52PVB + 8T (17.52mm) or 10T + 1.52SGP + 10T (21.52mm)
• Best for:​ Fully enclosed rooms with safety requirements
• Key benefit:​ Complete spatial definition with post-breakage protection

2.4 Sliding Laminated Partition

• Description:​ Laminated glass panels mounted on overhead tracks
• Glass build-up:​ 8T + 1.52PVB + 8T (17.52mm) – minimum
• Best for:​ Divisible rooms where safety is a priority
• Key benefit:​ Moving panels retain safety characteristics

2.5 Demountable Laminated Partition

• Description:​ Modular laminated glass panels with quick-release fixings
• Glass build-up:​ 8T + 1.52PVB + 8T (17.52mm)
• Best for:​ Leased offices requiring reusable safety partitions
• Key benefit:​ Safety performance maintained through multiple relocation cycles

11. Frequently Asked Questions – Laminated Glass Partitions

Q1: What is a laminated glass partition?​

A laminated glass partition uses two or more glass plies bonded together with a plastic interlayer (PVB or SGP). When broken, the interlayer holds the glass fragments in place, preventing dangerous falling glass and maintaining a barrier.

Q2: Why choose laminated glass over tempered glass for partitions?​

Laminated glass provides post-breakage retention​ – the glass stays in the frame after breaking. Tempered glass shatters into safe fragments but loses all barrier integrity. For high-traffic areas, schools, healthcare, and frameless systems, laminated is strongly recommended.

Q3: What is the difference between PVB and SGP laminated glass?​

PVB (Polyvinyl Butyral)​ is the standard interlayer – cost-effective, good post-breakage retention. SGP (SentryGlas®)​ is a high-performance ionomer interlayer – approximately 5× the tear strength of PVB, superior residual strength after breakage, and better edge stability. SGP is recommended for frameless systems and high-impact applications.

Q4: What thickness of laminated glass is used for partitions?​

Common thicknesses: 12.76mm (6+0.76+6)​ – budget; 17.52mm (8+1.52+8)​ – standard office; 21.52mm (10+1.52+10)​ – premium or tall partitions.

Q5: Does laminated glass provide acoustic benefits?​

Yes. Acoustic PVB interlayers​ can improve sound insulation by 3–5 dB compared to standard PVB, achieving Rw ratings of 42–48 dB depending on glass thickness and system design.

Q6: Can laminated glass be drilled for hardware?​

Yes, but all drilling must be completed before tempering and lamination. Holes are drilled in each glass ply separately, then the plies are tempered and laminated. Post-lamination drilling is not possible.

Q7: Is laminated glass required by building codes for partitions?​

Many building codes require safety glazing in specific locations – doors, sideline panels, areas within 500mm of circulation paths, and certain occupancy types (schools, healthcare). Laminated glass typically satisfies these requirements.

Q8: Can laminated glass be used for frameless partitions?​

Yes, and it is strongly recommended​ for frameless systems. Because there is no frame to contain broken glass, the post-breakage retention of laminated glass provides critical safety. SGP interlayer is preferred for frameless applications.

Q9: How long does it take to produce laminated glass partition panels?​

Standard PVB laminated: 3–4 weeks. Acoustic PVB: 4–5 weeks. SGP laminated: 4–5 weeks. Coloured interlayer: 5–6 weeks.

Q10: Can laminated glass be combined with other features?​

Yes. Laminated glass can incorporate frosting, ceramic frit printing, switchable PDLC film, coloured interlayers, and low-iron substrates​ – all while maintaining its post-breakage safety characteristics.
