Among the basic parameters determining the functional and aesthetic properties of clinker products are frost resistance, water absorption, bending strength, stain resistance, chemical resistance and fire resistance.

KING KLINKER products are manufactured using traditional method of drawing from plastic ceramic mass, which is a mixture of the highest quality clays. After the ceramic mass has been properly ground and homogenised, the products undergo the extrusion moulding process. Moulding is done wet with respect for traditional methods. After being moulded, the façade blick slips undergo a drying process followed by firing at temperatures exceeding 1000°C. The production method we use guarantees weather resistance, longevity and colour fastness.

The applicable regulations and standards set minimum parameters that all clinker products placed on the market must comply with. KING KLINKER products significantly exceed the requirements specified by the standards. Bending strength is twice as high as required, water absorption is maintained at around 3% and chemical resistance is up to a class higher than required. The frost resistance of our blick slips is 10 times higher than the standard requirements.

During use, KING KLINKER products do not release any harmful substances, which is why they are used both on façades and inside buildings. We use only natural raw materials in production. In addition, all production waste including clay-contaminated water is 100% reused in the production process.


Thanks to low absorbability, the tiles are weatherproof and perform well in areas exposed to higher levels of moisture.

for red and brown mass brick slip~ 3%
for white and yellow clay brick slip< 6%

Frost resistance

Frost resistance according to EN ISO 10545-12 – meets criteria

After being soaked in water, the brick slip are subjected to a minimum of 100 freeze-thaw cycles at temperatures between -5/+5°C. A test carried out by the Institute of Ceramics and Building Materials demonstrated the absence of any damage after 1,000 cycles (10 times the standard).

Reaction to fire

Reaction to fire class according to EN 13501 – A1

Non-flammable material – does not contribute to the development of fire. Even under developed fire conditions (800°C), it does not ignite (does not emit heat, smoke or flaming droplets or particles).


Bending strength

Bending strength according to EN 10545-4 – above 13 N/mm2

The test consists of determining the bending strength of the entire tile by applying a force of a certain magnitude at a certain distance from the centre of the tile.

Breaking force

Breaking force according to EN ISO 10545-4 – above 800 N

The test consists of determining the breaking load and breaking force by applying a force of a certain magnitude at a certain distance from the centre of the tile.
