🌟Explore 442 & 552 Laminated Glass – The Ultimate Engineering Solution for Modern Terrace Roof Covers & Glass Roofs
🔷 Where Architecture Meets Safety, Light, and Longevity
In the world of contemporary residential and commercial design, glass roofs are no longer just an aesthetic choice — they’re a necessity for sustainable, light-filled living spaces. At Explore, we engineer premium 442 (4mm+0.76mm PVB+4mm) and 552 (5mm+0.76mm PVB+5mm) Laminated Glass systems specifically for terrace roof covers, glass roofs, canopy glazing, and open-air architectural enclosures.
These high-performance laminated solutions combine structural integrity, thermal efficiency, visual clarity, and unparalleled safety — making them the gold standard in modern rooftop glazing across urban villas, penthouses, rooftop lounges, hospitality venues, and smart homes.
📐 Technical Specifications:Understanding 442 & 552 Laminated Glass
✅ 442 Laminated Glass (4mm+0.76mm PVB+4mm)
Total Thickness: 8.76 mm
Layer Composition:Two outer layers: 4mm Tempered Glass | Interlayer: 0.76mm PVB (Polyvinyl Butyral) | Inner core: 4mm Tempered Glass
Interlayer Type: High-strength, UV-stabilized PVB with superior adhesion and impact resistance.
Tempering: Fully toughened (tempered) on all external surfaces — enhances strength by up to 5x vs. annealed glass.
Load Capacity: Up to 120 km/h wind speed (Class 3 wind zone compliance).
Maximum Span Support: Up to 2.2 meters under standard clamping conditions.
Best For: Medium-span terrace roofs, private balconies, small verandas, residential rooftop extensions.
✅ 552 Laminated Glass (5mm+0.76mm PVB+5mm)
Total Thickness: 10.76 mm
Layer Composition: Two outer layers: 5mm tempered glass | Interlayer: 0.76mm PVB | Inner core: 5mm tempered glass
Key Advantage: Higher edge strength and bending resistance due to thicker outer panes.
Structural Performance: Engineered for large spans and dynamic loads — ideal for cantilevered designs.
Wind Resistance: Proven performance at up to 150 km/h (exceeds most European building codes).
Maximum Span Capacity: Up to 3.0 meters+ with proper framing support.
Best For: Large rooftop terraces, commercial rooftop cafes, luxury villa roofs, curved glass canopies, high-rise buildings.

🛡️ Structural & Environmental Performance
Terrace roofs face extreme conditions — from heavy rain and snow to intense UV rays, temperature swings, and storm winds. Explore 442 & 552 Laminated Glass is built to endure:
| Performance Factor | Specification |
|---|---|
| Impact Resistance | Survives hail (up to 25mm diameter), falling branches, accidental tool drops |
| Thermal Stress Resistance | Withstands rapid temperature shifts without cracking |
| UV Blocking | Blocks 99% of harmful UV radiation — protects furniture, flooring, and occupants |
| Noise Reduction | Reduces external noise by 25–35 dB (ideal for city centers) |
| Post-Breakage Safety | Fragments remain bonded to PVB layer — prevents injury and fall hazard |
