Clinkers / roof tiles (outdoor)

Burnt clay for terrace and path

Burnt clay clinkers for outdoor surfaces. Requires documented frost resistance for Danish climate — tile cladding clinkers are typically documented according to EN 1344 (supplier datasheet, not a landscape architecture standard); check water absorption and frost-thaw class on the datasheet. Thickness typically 4–6 cm; laid with joint sand. Source: NfA 1992 (thickness); supplier data (frost certification — advisory).
