CUPA 50: A natural slate suited to Ireland

Ireland’s roofing market demands materials that combine performance, efficiency and reliability, particularly in challenging weather conditions. Within this context, CUPA 50 has established itself as a dependable large-format natural slate, tailored to the needs of modern Irish construction.

Sourced from the prestigious San Vicente quarry in Northern Spain, CUPA 50 offers a smooth blue-grey surface and a consistently flat cut. It can be produced in larger formats, such as 60×30, aligning with Irish slating traditions and the demand for efficient installation.

CUPA 50 delivers proven performance in Irish conditions, combining strength, durability and resistance to wind and rain. Its larger format creates cleaner roof lines and a modern slate appearance, supported by the manufacturing expertise of the world’s leading natural slate producer.

Standing the test of time

With more than 25 years covering Ireland houses, CUPA 50 is a roof that stands the test of time and improves the value of any property.
