| Global Structural Certifications | CE, SGCC, EN14449, ASTM E1300 Structural Glazing Standard |
| Packing Solution | Export Solid Wooden Crates with cork separation to avoid edge damage |
| Performance Property | Standard PVB Laminated Glass | SGP Structural Laminated Glass |
| Material Stiffness | Medium soft plastic film, easy deformation | Ultra-High rigid ionoplast, outstanding stiffness |
| Edge Stability | Medium, easy moisture ingress & edge delamination outdoors | Excellent, anti-humidity, stable edge long-term exterior exposure |
| Moisture & UV Resistance | Medium, edge prone to delamination under long-term rain & sun | Excellent, resistant to harsh coastal, hurricane & high humidity climate |
| Structural Load Performance | Standard safety only, cannot share structural load | Outstanding, interlayer bears load jointly with glass for structural glazing |
| Post-breakage Integrity | Panel sags & falls once both glass layers crack | Panel stays upright as complete barrier even full glass breakage |
| Maximum Panel Span | Limited small & medium size panels | Supports extra-large frameless glass panels with minimal deflection |
| Unit Project Cost | Lower raw material & production cost | Higher cost due to premium ionoplast SGP interlayer |
Q1: Why choose SGP laminated glass instead of standard PVB?
A1: SGP uses rigid ionoplast structural interlayer with far higher stiffness, moisture resistance and load-bearing capacity. It keeps panels upright after breakage, supports large frameless spans and suits long-term exterior hurricane-prone projects, while soft PVB only meets basic indoor safety demands without structural performance.
Q2: Can SGP structural laminated glass be fully exposed outdoors?
A2: Yes. SGP interlayer features excellent UV and waterproof performance, no edge delamination or yellowing after long-term outdoor exposure, perfectly adapted to coastal, high-humidity and storm-prone open-air environments. Standard PVB is not recommended for permanent exterior structural glazing.
Q3: Is SGP laminated glass fully waterproof?
A3: The ionoplast SGP interlayer itself is highly moisture-resistant. With proper polished edge sealing processing, SGP glass can withstand long-term rain, sea salt fog and high humidity without layer separation.
Q4: Does SGP laminated glass delaminate over time?
A4: Under qualified edge sealing & normal construction environment, SGP almost never delaminates. Its solid ionoplast material absorbs negligible moisture, compared with PVB film which easily absorbs water and separates at edges after years of outdoor use.
Q5: When is SGP structural laminated glass required by building codes?
A5: SGP is mandatory for projects requiring structural load bearing: glass floors, glass bridges, oversized frameless balustrades, hurricane-resistant coastal facades, high-rise exterior curtain walls and overhead load-bearing skylights, where standard PVB laminated glass fails structural safety standards.
