Exterior doors with real stone create a striking impression of a modern entrance. The surface has a thin layer of slate stone that is unique to each door. The surfaces are durable, weather resistant and available in 3 different types of stone. Insulation, U-value, stability and other performance as well as warranties are as good as on our other range of exterior doors.
NOIR is a darker stone with soft shapes in the slate. With an exterior door from the Berg 160 series, the natural choice of material is accentuated, which creates a powerful entrance.
