よくある質問

Why the 10% waste factor?
A 10% overage accounts for cuts at edges and broken tiles during installation.
What are main runners?
Main runners are the long T-bar tracks spanning the room, hung from the structure above.
What tile size should I choose?
600×600 mm is standard. 600×1200 mm tiles use fewer but longer runners.
