Professional 11.14mm heat strengthened laminated glass factory supplies 5mm+5mm clear HS laminated glass with 1.14mm PVB interlayer. High flatness, low spontaneous breakage, ideal for railings, skylights, and overhead glazing.
What is an 11.14mm Heat Strengthened Laminated Glass?
11.14mm Heat Strengthened laminated glass is a high-performance architectural safety glass constructed from two 5mm heat-strengthened glass panels tightly bonded with a 1.14mm PVB interlayer.
HS glass is produced through controlled heating and cooling, creating moderate surface compressive stress. It maintains high flatness and stable thermal performance, making it less sensitive to uneven temperature changes common in large area glazing such as skylights and overhead structures. Combined with a laminated safety structure, this glass boasts good optical performance, thermal stability, and impact resistance. It is widely applied to high-end architectural railings and skylights where minimal visual distortion is required.
Tempered Laminated Glass VS Heat Strengthened Laminated Glass
| Performance Item | Heat Strengthened Laminated Glass | Tempered Laminated Glass |
|---|---|---|
| Surface Compressive Stress | Lower compressive stress | Higher compressive stress |
| Breaking Pattern | Larger, less-sharp fragments | Small granular fragments |
| Surface Flatness & Optics | High flatness, minimal optical distortion | Slight waviness, minor visual distortion |
| Thermal Stress Resistance | Moderate thermal stability | High instant impact resistance |
| Spontaneous Breakage Risk | Extremely low risk | There is a certain risk for long-term outdoor use |
| Main Application Focus | Overhead glazing, skylights, and large panel facades | High-risk collision-prone areas |
Application
This 11.14mm HS laminated glass is mainly designed for two core scenarios matching its performance characteristics:
1. Glass skylights & overhead glazing: For large‑area top glazing exposed to direct sunlight and uneven heat distribution, where low spontaneous breakage and high optical flatness are required.
2. Architectural glass railings & balustrades: For mid‑high‑rise balcony and stair railings, pursuing stable long‑term performance and clear visual effects.
How is this 11.14mm HS laminated glass made?
Cutting & Edge Polishing： Raw clear float glass is precisely cut and edge‑polished to remove sharp edges.

About FAQ
1. What is the key difference for project selection?
Tempered laminated glass is more focused on instant impact safety; heat strengthened laminated glass focuses on long-term thermal stability, low spontaneous breakage, and high optical flatness. Clients select according to project safety grade, exposure environment, and facade visual requirements.
2. How do you guarantee bulk quality consistency?
We adopt full-process inspection, including flatness testing, stress detection, interlayer adhesion inspection, and optical distortion control, ensuring uniform performance of each batch of HS laminated glass for large engineering orders.
3. Is long-distance transportation safe?
All glass is packed with export-grade plywood crates, foam protection, and paper interlayers.
