Polycarbonate Sheets: A Comprehensive Guide to Thickness and Design

Polycarbonate sheets, commonly known as sunlight sheets, have revolutionized modern architecture and construction with their versatility and durability. This guide explores the crucial aspects of thickness selection and design options to help you make informed decisions for your projects.

Thickness Options and Applications

Thin Sheets (2mm – 4mm)

These lightweight sheets are ideal for simple coverage applications and basic greenhouse construction. They offer:

• Excellent light transmission (up to 90%)
• Easy installation due to lightweight nature
• Cost-effective solutions for basic coverage
• Suitable for temporary structures and simple DIY projects

Medium Thickness (6mm – 8mm)

The most commonly used range for residential and light commercial applications:

• Enhanced thermal insulation compared to thin sheets
• Improved impact resistance
• Ideal for carports, patio covers, and walkway canopies
• Good balance between cost and performance

Heavy Duty (10mm – 16mm)

Perfect for commercial and industrial applications requiring superior strength:

• Maximum impact resistance
• Outstanding thermal insulation properties
• Suitable for heavy snow loads
• Ideal for commercial greenhouses and industrial roofing

Extra Heavy Duty (18mm – 25mm)

Specialized applications requiring exceptional strength:

• Maximum security and protection
• Superior sound insulation
• Used in high-end commercial buildings
• Ideal for areas with extreme weather conditions
