Produced with red, brown or white clay, these tiles are softer and less dense meaning they are easier to cut, drill and ideal for wall applications. Due to their high water absorption, ceramic tiles are always glazed.



A hard wearing stone that can come in a variety of colours from shades of white to deep black. It can be used in almost any environment due to the wide selection of finishes that can be applied to it.



Formed over millennia from limestone, this crystalline rock is extremely durable making it ideal for floors. Due to the creation process, veins and colour changes can appear in the stone which can look like faults but are actually an inherent characteristic of the stone and are of no concern. Marble can come in a variety of textures and finishes due to its versatile nature.


Porcelain -

These tiles are made with white clay and fired at a high temperature making them dense, hardwearing and perfect for floors. They have an extremely low water absorption rate of less than 0.5% making them well suited for bathrooms and wet rooms. Porcelain tiles can be glazed or unglazed.



A pale stone with inherent pits and holes which can be filled. It's marble-like qualities make it easy to cut making it suited for internal walls, floors, showers and hearths. It is not recommended for outdoor use as it is susceptible to frost damage.

Production & Colour Terms


This process involves removing the edges of the tile to give a cleaner finish and meet size specifications. Tiles cut in this manner have a uniform size thereby reducing grout joints to a minimum.


Rectified Glazed Porcelain

These are porcelain tiles that have been cut during the manufacturing process to meet the exact sizing requirements. They are much more aesthetically versatile, coming a variety of finishes including matt, glazed, metal effect or stain.



Non rectified tiles have natural, uneven pressed edges that may vary slightly in size and require a wider grout gap.



A term that refers to the print or pattern on the tile which has been applied using an ink-jet printer.



This refers to tiles whose surface colour is the same all the way through the tile. Also known as 'through-bodied' or 'technical' porcelain, these tiles are made of a single material with no glaze applied making them extremely hard wearing and perfect for any application.

Texture, Finishes & Format Terms


The stone's surface is brushed with rotary diamond pads, resulting in a textured finish to the surface and rounded edges.


Cushioned/ Pillowed

The straight edges of a tile have been rounded and softened.



Voids, pits and holes (a natural characteristic of some stone) in a tile have been filled with a resin to create a smooth surface.



A machine process which results in a smooth, matt surface.


Lightly Polished

The tile's surface is polished to a softly reflective sheen.



The tile's surface is buffed by a machine, resulting in an even, smooth and highly reflective surface.



The surfaces of the stone have been textured, worn and weathered by contact with abrasive materials.



Voids, pits and holes within travertine have not been filled prior to installation. However, they can be grout filled.


Bevel Format

The tile has been cut to create angled edges that slope away from the flat top surface.
