Cupa Heavy 3 slate creates a roof for Life!

HEAVY 3 slate naturally possess the density and resilience required to cope with the most volatile of weather conditions, and with an unrivalled thickness of 7.5mm this product’s quality and durability is unequivocal.


A poor quality roof needs constant repair and maintenance, but when good quality slate is used, those expenses during its lifetime are extremely low. Since CUPA PIZARRAS’ slate entered the Scottish market in the early nineties there have been no HEAVY 3 slate re-roofing incidents.


The slate characteristics depend on where it has been extracted. That is why it is imperative to validate the reputation from both the quarry and the company which produces it.


Heavy 3 slate is quarried from the CUPA PIZARRAS No 3 quarry in northern Spain since 1892. During these 125 years HEAVY 3 has earned its reputation as a reliable and versatile product. With such a long pedigree, CUPA PIZARRAS’ confidence in its products and its high standards of quality are further substantiated by its unwavering 100-years warranty.


HEAVY 3 possesses a breadth of aesthetic and practical advantages; medium-grained and blue-black in colour with occasional quartz grains detectable on the surface, it is visually appealing. Also, as well as being impermeable, non-combustible, UV resistant and unaffected by chemicals and pollutants, HEAVY 3 is repellent to the growth of mould and fungi making it suitable for all environmental conditions.


The product’s popularity has gained momentum in Scotland due to its close resemblance to the traditional highland slate from Ballachulish that is no longer produced. This factor alone makes HEAVY 3 the primary choice for traditional Scottish slate roof replacements or repairs.


The benefits extend further still – significantly thicker than all of its competitors, HEAVY 3 provides maximum endurance against the high wind speeds and driving rain that is so common throughout Scotland and is therefore ideal for new-build roofing projects too.
