Centurion supplies Opal (click to view sample) polycarbonate as standard, but you can choose Clear, Silver Opal or Bronze tint if you prefer. If you need a solar control alternative to help keep a South facing conservatory cool, the Silver/Opal option reduces heat penetration by up to 50%. All our polycarbonates are 35mm thick (that's seven layers of polycarbonate with six air spaces), offering a "U" value of 1.4 and excellent noise insulation as well.
