Silestone Quartz Surfaces

What is Silestone?

Silestone is a compound made up of 94% natural quartz, which makes it extraordinarily hard and resilient. This is the one and only worktop made of quartz with anti-bacterial protection, giving it hygienic properties that are not to be found anywhere else on the market. It is an excellent surface for kitchen worktops, bathrooms, floors and wall cladding using the minimum number of joints.

In addition, it comes in a variety of different shades of quartz color, offering a number of decorative possibilities from a mere kitchen top to a project for a complete set of furniture. Silestone is an investment for the future. Silestone is forever.

About Quartz

Quartz is crystallised silicon dioxide (SiO2), which is usually white or transparent, although it can be found in other colors if it comes into contact with impurities during its formation.

It is found either in a pure state or present in other compounds. However, because of its extreme hardness and resistance to acids, it is used to make a large variety of products that require precision and top-quality performance. This type of quartz forms the main component in Silestone boards.
