Versatile Requirements for a Flat Roof

The first thing we probably all think is that the roof over our heads must be impervious in the first place. Of course, but it also has to fulfill other requirements. For example, greenery on flat roofs supports biodiversity and has a cooling effect in summer under strong sunlight. If exposed roof surfaces are equipped with solar cells, these convert the sun's rays directly and emission-free into electricity through photovoltaics. And when it rains, the flat roof catches large quantities of water (retention) and relieves the local sewage system through anticyclical drainage.

Digitally Networked Quality Assurance in Two Stages

The LQS Roofing System supports you in two stages during and after the welding process. 

#1 Immediate help with digital welding assistant: As soon as you leave the entered welding parameters during the welding process, the automatic welder signals and informs you with an acoustic and optical warning signal. Using a marker, you can check your weld seam immediately after completing the work with the weld seam tester.

#2 Automatic welding reports: The LQS function automatically records the relevant welding parameters of temperature, speed and air volume. The data is presented in a PDF report and contains representations of the parameters as graphs and in tabular form including GPS coordinates.
