Quarried in the highly renowned La Bana region in Northern Spain. Our Estillo 33 Blue Grey has a dark blue grey to black colour. The slate is available in two thickness selections, Prime 4mm and Premium Heavy 7mm, thus giving the architect, developer or contractor a choice which will suit the desired overall aesthetics of the project.
The prime selection is extremely flat and consistent, requiring minimal grading prior to laying. This allows for a very clean, crisp finished roof appearance.
The blue grey colour will not fade over time, therefore outperforming many of its similarly cost effective oppositions.
The Estillo 33 does have small metallic surface inclusions scattered across the surface of the slate, but these are stable and will not “bleed” down the roof.
The slate has outstanding test results offering fantastic resistance to weather conditions.
Fully Tested to BSEN12326-1:2004, attaining A1, T1 & S1 certification.
