Our polycarbonate sheets are available in six different thicknesses. These include 4mm, 6mm, 10mm, 16mm, 25mm, and 35mm. Each is purposely designed for different applications, ranging from balcony dividers to conservatory roofing.
If you intend to use our multiwall polycarbonate sheets for a roofing project, be sure to use between 10mm and 35mm. If you're using it to create a safety barrier on a balcony or other form of cladding, either 4mm or 6mm is ideal. The thicker the polycarbonate is, the more strength it will provide.
