Duquesa For Grace

The Duquesa is a Spanish slate quarried in the highly regarded La Bana region of Northern Spain.

Its distinctive Hebra riven texture and blue/black colour make it a popular choice for roofing contractors, and builders. This brand new slate offered in Scotland is heavier and comes in a 7-9mm thickness, making it perfect for the harsher weather conditions.

Prime Grade slates are of a high quality and good selection, they will require slightly more sorting and grading prior to fixing than the Ultra-Grade, but once done Prime-Grade slates offer a cost-effective solution that will still achieve a flat, uniform appearance on the roof. 

Sizes Available:

400×250 mm

Test results: The Duquesa slate boasts a W-1, T-1, S-1 rating, meaning it conforms and surpasses all the top UK tests for water absorption, thermal cycle resistance and sulphur dioxide exposure.
