This guide covers the key factors to consider when specifying polycarbonate sheets.<\/p>\n<h2>Thickness Options and Their Applications<\/h2>\n<p>Polycarbonate sheets are available in a wide range of thicknesses, each suited to different applications:<\/p>\n<ul>\n<li><strong>2mm\u20133mm:<\/strong> Decorative applications, temporary structures, display cases<\/li>\n<li><strong>4mm\u20136mm:<\/strong> Residential greenhouses, small carports, patio covers<\/li>\n<li><strong>8mm\u201310mm:<\/strong> Commercial greenhouses, large carports, skylight glazing<\/li>\n<li><strong>12mm\u201316mm:<\/strong> High-load applications, sports halls, industrial skylights<\/li>\n<li><strong>20mm\u201325mm:<\/strong> Extreme load requirements, noise barriers, security glazing<\/li>\n<\/ul>\n<h2>Key Factors in Thickness Selection<\/h2>\n<h3>1. Span Between Supports<\/h3>\n<p>The distance between purlins or support structures is the primary factor determining required thickness. As a general rule, longer spans require thicker sheets. For a 1.2m purlin spacing, 8mm twin-wall polycarbonate is typically the minimum recommended thickness.<\/p>\n<h3>2. Snow and Wind Load<\/h3>\n<p>In regions with heavy snowfall or high wind speeds, thicker sheets or multi-wall profiles are essential. Always consult local building codes for minimum load requirements.<\/p>\n<h3>3. Light Transmission Requirements<\/h3>\n<p>Thicker multi-wall sheets have lower light transmission than thinner solid sheets. Clear 4mm solid polycarbonate transmits approximately 88% of light, while 25mm multi-wall transmits around 50%.<\/p>\n<h2>Solid vs. Multi-Wall Polycarbonate<\/h2>\n<p>For most roofing applications, multi-wall (twin-wall or triple-wall) polycarbonate is preferred over solid sheets due to better thermal insulation and higher strength-to-weight ratio. Solid sheets are better for applications requiring maximum light transmission or optical clarity.<\/p>\n<h2>Conclusion<\/h2>\n<p>When in doubt, always specify one size thicker than the minimum calculated requirement.
