The concourse enclosure, which will house the holdrooms and passenger transportation means, is comprised of 5-pin arch truss girders with an alternating system of glazed facades and a translucent fabric membrane set-up, which is spanned to bridge the 27 m spacing between the glass facades. The laminated glass of the glass facade will receive a sun protection coating and a ceramic frit of variable densities. While the fritting is relatively dense at the rooftop to achieve good solar protection against the high standing sun in Thailand, it decreases gradually towards the lower parts to allow for good views to the outside.
