Slates and Phyllites

Slate and phyllite are the main types of natural stone in the Naturpiedra Jbernardos range. They make up a wide range of products, in different tones and finishes, which offer a variety of construction solutions; such as roof coverings, dimensioned tiles or in irregular format for flooring and cladding, masonry, pre-assembled panels, paving and all kinds of solutions for gardens and landscaping as decorative stone.

It is one of the most widely used natural stones in construction. It is highly valued, for example, for its impermeability. It has therefore been used since ancient times as a material for roofing, cladding and flooring. We can also highlight its sustainability, having a very low environmental impact and carbon footprint, together with great durability. This makes it a very ecological and appreciated material for sustainable and passivhaus construction.

It is considered a metamorphic rock, composed of fine-grained clayey sediments, which are presented in sheets or layers, allowing the material to be hand-sliced. Normally of dark shades of grey to black, there are also multicoloured varieties, red or green; in opaque, satiny tones without shine.

As Spain is the main producer and exporter of slate in the world, the Naturpiedra quarries in Bernardos, Segovia, are the oldest quarries in Spain that have been exploiting this type of natural stone. They extract Filita Gris, a material with a higher degree of metamorphism than the average slate, which is characterised by its great hardness, diversity of finishes and satin shine. It has been used in the roofs of historical buildings of National Heritage for 5 centuries and has been used uninterruptedly up to the present day.

Naturpiedra also completes its range with the different slate offered by our collaborating quarries, both national and imported, making up one of the widest offers of this material on the market, both in number of products and in variety of tones, formats, finishes and uses for which they are intended.
