Choosing between a head with a 2mm (SUPA2) or a 4mm (SUPA4) gap is mainly aesthetically driven (taking into consideration that in outdoor installations a wider joint between the tiles is not as evident as in indoor installations). The advantage of using a head with a 4mm gap is being able to do the final height adjustments using the SUPAK tool, even after the floor is installed, without having to remove any pieces. In addition, the 4mm head can also be used with installations containing aluminum joists.

For the installation of large format tile on raised floors Profilitec recommends using the SUPAAN aluminum profile (joist) which is placed on top of the pedestal and, in addition to giving the structure more stability, also facilitates and speeds up the tile installation. The distance between SUPAAN joists should not be greater than 60cm, and the same rule applies for the underlying pedestals.

Ceramic tiles with a thickness of 2cm are most commonly used outdoors, especially in floating floor installations. When installing a floor supported by pedestals, however, the floor covering can be thicker or of other materials, such as stone, marble, etc. We recommend always respecting the maximum load capacity of 14kN per pedestal and maintaining a maximum distance of 60 cm between pedestals.
