What is 8mm Toughened Tempered Glass?
8mm Toughened Tempered Glass is a high-strength safety glass manufactured by heating float glass to 700°C followed by rapid cooling (quenching). This process creates surface compression, making it 4–5x stronger than regular glass. When broken, it fractures into small, blunt granules, minimizing injury risks.
Key Characteristics:
- Thickness: 8mm (5/16″) for lightweight yet durable applications.
- Safety Compliance: Meets EN 12150, ASTM C1048, and AS/NZS 2208 standards.
- Optical Clarity: 91% light transmission for unobstructed views.
- Thermal Resistance: Withstands temperatures from -30°C to 250°C.
Applications:
- Glass roofs for pergolas and conservatories
- Winter garden partitions and skylights
Why 8mm Clear Toughened Safety Glass is Suitable for Pergola and Winter Garden?
1. Structural Performance
- Weight Efficiency: At 20 kg/m², it reduces load on supporting structures.
- Wind Load Resistance: Withstands up to 2.5 kPa (BS 6399 Part 2).
- Snow Load Capacity: Supports 1.0 kN/m² (typical for temperate climates).
2. Thermal Efficiency
- Solar Control: Blocks 85% of UV rays to protect interiors.
- Insulation: Reduces heat loss by 30% compared to single-pane glass.
3. Safety & Durability
- Impact Resistance: Survives hail up to 25mm diameter (1,100 kJ/m²).
- Weatherproof: Resists humidity, frost, and corrosion.
4. Aesthetic Versatility
- Frameless Designs: Enhances modern architecture.
- Custom Tints: Bronze, gray, or green options for style and glare control.
5. Cost-Effectiveness
- Lower Material Costs: 20% cheaper than 10mm glass.
- Installation Savings: Easier handling reduces labor time.
