Product Description

Silestone Unsui is a soft, dark brown quartz stone with a consistent, uniformly coloured base and a totally plain design that allows for applications in both traditional and modern architectural and interior designs from the Zen Series by Cosentino.

The Zen Series of Silestone which is composed by a collection of 5 truly amazing colours stones bring limitless design combinations available to any home, residential properties, offices and commercial establishments.

The Zen Series revolutionized the quartz surfaces’ sector at its launch and was inspired by the Zen Japanese philosophy based on Buddhist principles of concentration and meditation which provide insights to one’s true nature and a liberated way of life.

Silestone’s reinterpretation comes to interior properties by the adoption of a collection of 5 plain colours including Haiku, Gedatsu, Negro Tao and Silestone Kensho quartz.

Further to the aesthetical and visual advantages of Silestone surfaces there are mechanical properties that enhance the performance of this material such as being a quartz surface that is highly resistant to staining from coffee, wine, lemon juice, olive oil, vinegar, make-up and many other everyday products.

Quartz is one of the strongest minerals known to man. This makes Silestone products extremely durable, with a high level of resistance to external aggressors. The high level of resistance of Silestone quartz worktops to knocks far surpasses that of other products with similar applications (granite, marble, solid surfaces, etc). This resistance and durability provides peace of mind in the kitchen.

To top it all up, Quartz has a hardness of 7 in the Mohs hardness scale (diamond is number 10). Therefore, whereas with the majority of other worktops, such as those made of granite or laminate, which can get scratched, with Silestone no mark is le…. Silestone is highly resistant but should not be treated with reckless force; care needs to be taken with knife blades
Silestone Unisui is available in sheets with dimensions of 3040x1380mm and Jumbo sizes of 3250x1590mm which allow for large, seamless designs. With available thicknesses of 12mm, 20mm and 30mm; it provides end clients, interior designers and architects with endless choices for their project.

Silestone Unsui is available in a polished finish which offers unrivaled sheen and consistency to any space in which it is installed.
