Tondach Wiener Norma

Tondach Wiener Norma is a simple and harmonious roof tile, which, with its unobtrusive shape, is suitable for traditional roofs. It is a large-format brick roof tile with a deep double frontal and side notch, which allows for very good sealing against the ingress of water, snow and dust. Due to the very large possibility of movement in the covering length, it is optimally useful in the rehabilitation of existing roofs.

Minimum slopes according to ÖNORM B 3419:
From 17° – using a secondary covering with increased requirements
From 20° – using a secondary covering
From 27° – without secondary covering
