CUPA HEAVY 3

Share:

HEAVY 3 is a blue black slate with a slightly gritty texture, and in some samples well defined parallel lines are clearly visible on the cleavage surfaces.

HEAVY 3 can last over a hundred years, making it a very cost-effective roofing material.

Its extra thickness of 7-8 mm gives it the perfect strength to withstand any weather conditions while boosting the value of any property.
