Rooftec’s solution was to create a hexagonal free-standing conservatory with a ‘northlight’ above using the Aztec conservatory roof system, and glaze the roof elements with 10 sheets of 25mm Marlon ST Heat Guard Opal. This popular multi-wall polycarbonate is used primarily and extensively to create commercial canopies, conservatories and municipal and domestic swimming pool roofs. It offers a high strength to weight ratio, high impact resistance, Class 1 surface spread of flame, high optical clarity, insulation performance and light transmission of up to 88%.
