Tegalit STAR roof tiles are made with sandwich technology, which consists of a fine-grained cement paste layer applied between the larger granular concrete tile body and the surface paint layer, which reliably clogs open pores. This creates a perfectly smooth, glossy tile surface that provides outstanding long-lasting protection against dirt (moss, algae) and weathering. Uniquely in Hungary, the nasal part of the Tegalit STAR roof tile is treated with the same surface treatment as the roof tile.
