Description
The Corotherm 16mm Triplewall Clear Polycarbonate Sheet (4000mm length) offers a durable, lightweight, and versatile roofing solution designed for larger projects and extended spans. Perfect for conservatories, carports, pergolas, greenhouses, walkways, and other outdoor structures, this 4m length minimises the number of joins required, delivering a seamless, professional finish.
Engineered for strength, the sheet withstands snow and wind loads of 0.6kN/m² while providing excellent thermal insulation to keep spaces warmer and more energy efficient. Its clear finish ensures outstanding natural light transmission, brightening any area while maintaining a clean, modern appearance.
Each sheet can be cut to size for precise fitting and is designed for straightforward installation using a proprietary glazing bar system. The sheet is secured at the top with glazing bars or wall flashings and fixed at the bottom edge with a single fixing button. With 20mm edge engagement and flutes running lengthways, correct installation in line with the roof slope or pitch is essential for best performance.
For safety, glazing bars should not exceed a maximum spacing of 1050mm, as wider spans can risk dislodgement during heavy snow or strong winds.
