What are oversized glass panels and who needs them?
The term "oversized" describes any glass panel exceeding standard transport and handling capabilities — in practice, any sheet larger than 2,500 × 3,500 mm or heavier than 150 kg per panel.
Glass types for large format shopfronts and windows
1. Tempered safety glass
Thermal tempering at 620–680°C increases glass strength 4–5 times. At breakage, fragments into small granules without sharp edges.
Standard specifications: 8–19 mm thickness, maximum sheet size 3,500 × 8,000 mm.
2. Laminated glass (VSG) — burglar resistance classes
| Class (EN 356/EN 1627) | Resistance | Typical application |
|---|---|---|
| P2A / RC2 | 3 min with screwdriver | Standard retail |
| P4A / RC3 | 5 min with crowbar | Jewellery, pharmacies |
| P6B / RC4 | 10 min with drill | Banks, exchange offices |
3. Large format thermal glazing
- 4+16+4 argon: Ug = 1.0 W/m²K — commercial standard
- 6+16+6 argon + Low-E: Ug = 0.6 W/m²K — premium showroom
- 8+16+8 tempered + Low-E — combined resistance + insulation

Frequently Asked Questions
From what dimensions is glass considered oversized?
"Oversized" describes any glass panel exceeding standard transport limits — in practice, any sheet larger than 2,500 × 3,500 mm or heavier than 150 kg. It is required by car showrooms, premium retail, restaurants, offices, hotels and premium residential with floor-to-ceiling windows.
What type of glass is used for large shopfronts?
Toughened (heat-tempered) glass is the standard for shopfronts. Tempering at 620-680°C followed by rapid cooling increases strength 4-5 times over float glass. On breakage it fragments into small granules without sharp edges — essential for safety in public spaces.
What are the maximum dimensions of a toughened glass sheet?
A toughened glass sheet can reach maximum dimensions of 3,500 × 8,000 mm, in standard thicknesses of 8, 10, 12, 15 or 19 mm. These dimensions allow panoramic shopfronts of 3-5 m wide with no visible vertical joint, ideal for showrooms and retail façades.
Why is toughening important for public spaces?
Toughened glass, on breakage, fragments into small granules without sharp edges, unlike float glass which produces dangerous shards. This is essential for safety in showrooms, shops, restaurants and any public space with heavy footfall.
