The weight of porcelain stoneware tiles per square metre varies, depending on two essential factors: size and thickness. Tiles of the same size will vary in weight depending on thickness: slim (4.9 mm or 6.5 mm), standard (9 mm or 10 mm) or extra-thick (12 mm, 14 mm and 20 mm). So the thicker the tile, the heavier the weight, as you can see in the table below, showing square metres and kilograms both per square metre and per full pallet:
Why choose slim porcelain stoneware tiles?
Conceived mainly for use in renovation projects, to simplify and streamline wall and floor covering operations without removing existing materials, Sottile 4.9 mm-thick and Kontinua 6.5 mm-thick porcelain stoneware tiles can be used for all projects requiring light weight and reduced thickness.
The main advantages offered by slim tiles: simplification and streamlining of laying operations, avoiding the need to remove existing material; less time required for laying, so settings are ready to use more quickly. This reduces the inconvenience typically caused by renovation. There are no costs for the removal and disposal of existing floor and wall coverings, and less work is required for changes and repairs, such as the removal of door and window frames and adjustment of floor levels. It also makes it easier to work, cut, perforate and handle the ceramic material. The bearing structure and the floors have less weight to support, and the environmental impact is lower thanks to the savings on raw materials and energy.
When to choose 20 mm-thick tiles
Extragres 2.0 comprises Casalgrande Padana’s 20 mm-thick tiles: a wide range of stone-effect, wood-effect and concrete-effect porcelain stoneware tiles intended mainly for outdoor flooring: terraces, walkways on lawns, gravel and sand. Extragres 2.0 tiles can be glued to screed, for excellent load resistance, or laid directly on gravel, sand or grass. This flooring can be walked on immediately, without the need for screed or the use of mortar and glue.
Finally, the 20 mm thickness can be used to create raised floors, using polypropylene supports with fixed or adjustable heights. Raised flooring for outdoors is easy to remove and inspect, and electrical or plumbing systems can be housed in the gap below.
The fixed supports, available in heights of 14 mm, 25 mm or 35 mm, are ideal for floors that need to be removed and inspected easily.
The adjustable supports come in different heights, from 35 up to 100 mm, and are perfect for levelling up uneven ground.
