Virtually opaque for softer, more ambient light and privacy with solar control, this Corotherm opal-tinted roof sheet offers a light transmission of 30%, meaning you can still enjoy the benefits of the sun while reducing glare which is especially important if you are working or studying.
Extremely energy efficient with a U-value of 1.6W/m²K, this Sevenwall polycarbonate sheet from Ariel Plastics provides excellent thermal insulation. It is lightweight yet resistant to impact with protection against vandalism, hailstones and accidental damage. Effortless to cut, handle and install, it is ideal for a wide variety of glazing and roofing applications around your garden and home, including greenhouses, carports, veranda covers and canopies.
With up to a 'Class 1' fire rating, this polycarbonate roof sheet is self-extinguishing and will melt away from flames, stopping as soon as the source is removed. Thanks to its low weight, lighter support structures can be used for a cost-effective building solution.
Please note:
Question:
If I buy 2100 width and the old panels are 1000 with the joins on the joists ,do the wider ones have to be on joist,or is there a self supporting joining strip . The old one leaked on the joints and I couldn't seal from underneath .
Answer:
In terms of installation, it's generally recommended to secure the panels on the joists for optimal support and stability. However, if you're considering wider panels and concerned about potential leaks, you may want to consider a joining strip. The Marlon 25mm Opal Sevenwall Polycarbonate Roof Sheets are designed with a sevenwall profile which provides enhanced rigidity and strength. They are also impact-resistant and come with a 10-year warranty. This might reduce the chance of leaks occurring.
