"We always use the CUPA PIZARRAS Heavy 3 on all of our projects. Strong and impermeable, the thicker 7-8mm variant is most definitely the preferred choice in Scotland with the extra thickness and weight giving it strength to withstand the high wind speeds and driving rain common across the country."

"For the roof, our priority was to source a good quality natural slate that would last and withstand the inclement Scottish weather conditions. Following extensive research, we discovered and specified Cupa Pizarras Heavy 3."

"The very nature of Scottish architecture lends itself to selecting a natural slate roof. Having used the CUPA PIZARRAS Heavy 3 slate on our own roof many years ago, as a practice, it’s our go-to slate of choice for projects that require a high-quality and durable product."

"Heavy 3 was ideal for this project due to its close resemblance to the traditional highland slate from Ballachulish that is no longer produced, making the CUPA PIZARRAS slate now the primary choice for traditional Scottish slate roofing, whether it be for new or refurbished roofs. In addition, it is the only slate that can successfully withstand the Scottish weather, thanks to its thickness of 7-8mm"

"We used CUPA Heavy 3 natural slates because they met the strict Planning guidance and were ‘tried and tested’ in rural Scotland. Allan Liddell was extremely helpful during the design stage by developing a specification for random width slates laid in diminishing courses."
