Saugaat Inc. is at the cutting edge of innovation, redefining the possibilities of glass in modern architecture. With breakthroughs in interlayer technology, glass is no longer just a passive material—it has evolved into a dynamic structural element that pushes the boundaries of design. The latest advancements, particularly in interlayer formulations, significantly enhance the strength and load-bearing capacity of laminated glass. This allows for sleeker, lighter panels without sacrificing durability. However, for demanding applications – especially overhead glazing – options that meet the highest stiffness and post-breakage performance standards remain scarce.
Kuraray’s Trosifol® Extrastiff Pro: A New Standard In PVB Interlayers
Kuraray’s Trosifol® ExtraStiff Pro raises the bar for PVB interlayers, delivering exceptional structural integrity and longevity. Engineered for high-performance applications, it outperforms conventional structural PVB interlayers, offering unmatched load-bearing capabilities and resilience. Whether used in expansive glass façades, high-rise buildings, or complex architectural installations, it ensures superior safety and design flexibility.

Structural Performance Comparison
In real-world applications, performance is everything. To compare interlayers, a rigorous EN 16613 Human Line Load Case test was conducted under demanding conditions.
Test Conditions:
- Panel Dimensions: 1500 mm (W) x 1100 mm (H)
- Glazing Configuration: Bottom-edge supported / cantilevered/vertical (90°)
- Laminate Composition: 2 x 8 mm fully tempered glass + 1.52 mm interlayer
- Load Applied: 1.50 kN/m at 30°C for 30 seconds
| Interlayer Type | E(t)-Modulus (MPa) | Deflection (mm) | Performance Comment |
| Trosifol® ExtraStiff Pro | 12 | 10 | Superior – Extremely Stiff |
| Competitor Stiff PVB | 7.1 | 15.1 | Good |
| Standard PVB | 1.2 | 22 | Weak |
The results speak for themselves. Trosifol® ExtraStiff Pro delivers superior stiffness and minimal deflection, making it the go-to choice for architects and engineers who refuse to compromise on safety and performance.
