Replacement of the end-of-life glass rooflights, originally installed in 1981, that run the length of the Terminal building above the Check in Desks and Security check in the International Departure Lounge. Updating these required that any new materials to be ASAID-compliant with regards to blast performance and the existing curtain wall frame had to be retained so as to minimise the impact of the works to the terminal building.
Over 1750m2 of Kalwall Skyroof system, utilising the existing curtain wall framework as structural support. All works were completed within engineering hours causing minimal disruption to the terminal building.
The Kalwall skyroof is now classed as walk-on, enabling simple maintenance of the works and surrounding areas for future use, with additional opportunities now being explored by the airport overall.
The works were so successful that Structura was awarded ‘Most Promising New Supplier’ by Balfour Beatty.
