A glass bottom and equally transparent glass walls make a swimming pool with unusual views a special eye-catcher. At the same time it functions as a roof light for the display area of an Austrian pool specialist. The two sedak glass elements transform the swimming pool into a socalled “infinity pool”. They give the swimmer the Feeling of a limitless swimming experience at a height of five meters. At the same time they demonstrate the performance capabilities of the material: the pool is around 1.2 meters deep, exerting a load of around 38 tons of water on the 13 x 2.5 meter insulation glass that forms the bottom of the pool. Constant pressure on the glass walls of the pool also challenges the material there.
