To reduce heat build up and solar glare, Marlon ST Longlife multiwall sheets are available in solar controlling dual tints. By deflecting sunlight, the heat controlling outer layer is effective in reducing solar heat gain through the roof by up to 50%. The attractive inner opal layer acts to provide a soft diffused natural light. A popular choice in conservatories and lean-tos, dual tints provide a comfortably cool, naturally daylit interior space. Dual tints include Heatguard Opal and Bronze Opal.
