Photocat has supported Bauder and implemented production facilities enabling Bauder to deliver Karat Air+ based on Photocats unique air cleaning technology, to meet the demand of sustainable bitumen dachbahnen. Bauder is industry leading in Europe and has received the award Architects darling 2019. The launch takes place from the 800 square meter exhibition-booth, where the features of the new dachbahnen is demonstrated. A through time measure system developed by Photocat supports the launch by demonstrating the efficiency of the membrane to roofers, city-planners and architects at the fair.
