Customer reviews
“I like the guaranteed consistency of appearance from CUPA 12. With lower specification products you can get impurities in the slate and colour variance, which can stand out on larger roof areas. They can also be quite brittle, which means there is a lot of wastage. You get none of this with CUPA 12."
"CUPA 12 slate has a soft, natural aesthetic and is consistent in its appearance, which is ideal for a modern build. It’s also great quality and our roofer loved working with it."
“For the overall look of the house to be consciously contemporary, using large windows to maximise light. The use of CUPA 12 helps to give the building a natural, yet sleek and contemporary finish.”
“There were a number of reasons for putting forward the Cupa R12 slate to the customer. It was a job where quality and longevity were paramount and we know that is always certain with Cupa, with the R12 offering a 100 year guarantee.”
