It is the first, only and real capped sandwich panel produced in Turkey. The biggest advantage of the Master Panel is that the panel fasteners are protected from external factors by means of a cap profile that covers the panel joint point, and that there are no water leakage problems in the panel joint and the fasteners over time. It also provides a visual advantage by making the cap profiles in different colors upon request. In addition, the roof can be covered with a minimum slope of 5% by using the Master Panel, and it can also be used as a facade panel, thanks to the cap profile hiding the fasteners.
