Tiles on terraces and balconies are beautiful when the edge is also perfect. The balcony angle profile of the DURABAL BT 11 series is robust and beautifully shaped and offers a wide, pre-drilled support leg for secure thin-bed laying and covers the ugly visual edge of the substructure (sealing, screed, drainage). The 11 mm upstand has drainage holes and the drip edge prevents soiling of the façade.
