What is Meant by Frost Resistance for Ceramic Tile?

Ceramic tile frost resistance is defined as the ability of ceramic tile to withstand freeze/thaw conditions with minimal effect.

The frost resistance of ceramic tile is dependent on the tile’s porosity and water absorption levels.

Frost damage can occur when ceramic tiles absorb moisture through their pores, causing the water to freeze internally when temperatures drop. Since water expands when it freezes, tension is then exerted inside the body of the ceramic tile. This internal pressure may become high enough to cause cracks in the ceramic tile.

For locations characterized by below zero temperatures at any time of year, you must ensure that you choose ceramic tiles with frost resistance for outdoor installations.
