Glass Load Tables
Maximum recommended pane sizes for common glass configurations under different design loads. Values are based on SS EN 16612 and ASTM E1300 for simply-supported rectangular plates.
| Configuration | 1.0 kPa (mm × mm) | 1.5 kPa (mm × mm) | 2.0 kPa (mm × mm) | Typical Application |
|---|---|---|---|---|
6mm Tempered | 1200 × 1800 | 900 × 1400 | 800 × 1200 | Standard windows, internal partitions |
8mm Tempered | 1600 × 2400 | 1200 × 1800 | 1000 × 1500 | Large windows, balcony doors |
10mm Tempered | 2000 × 3000 | 1500 × 2200 | 1200 × 1800 | Shower screens, frameless doors |
12mm Tempered | 2400 × 3600 | 1800 × 2600 | 1500 × 2200 | Glass floors, balustrades, large façades |
6+1.52PVB+6 Laminated | 1400 × 2000 | 1100 × 1600 | 900 × 1400 | Overhead glazing, safety balustrades |
6+1.52SGP+6 Laminated | 2200 × 3200 | 1800 × 2600 | 1500 × 2200 | Structural fins, canopies, frameless balustrades |
Values assume simply-supported edges, tempered glass with characteristic strength f_k = 120 MPa, and safety factor ≥ 2.5. For project-specific calculations, use ourGlass Interlayer Calculatoror contact our engineering team.
Singapore Wind Pressure Zones
Design wind pressures per SS EN 1991-1-4 Singapore National Annex for different building heights and exposure zones. Use these values in our calculator or your own structural analysis.
| Building Height | Zone A (Open) | Zone B (Suburban) | Zone C (Urban) | Zone D (CBD) |
|---|---|---|---|---|
| ≤ 10m | 1.00 kPa | 1.15 kPa | 1.30 kPa | 1.45 kPa |
| 10 – 20m | 1.15 kPa | 1.30 kPa | 1.50 kPa | 1.65 kPa |
| 20 – 30m | 1.30 kPa | 1.50 kPa | 1.70 kPa | 1.85 kPa |
| 30 – 50m | 1.45 kPa | 1.65 kPa | 1.85 kPa | 2.00 kPa |
| 50 – 100m | 1.65 kPa | 1.85 kPa | 2.05 kPa | 2.20 kPa |
| > 100m | 1.85 kPa | 2.05 kPa | 2.25 kPa | 2.40 kPa |
These are simplified values for preliminary design. Final submissions require site-specific wind tunnel data or detailed SS EN 1991-1-4 calculations with terrain category, building shape, and dynamic response factors. Our engineering team provides certified calculations for BCA submissions.
