Product Guide

Monoceram have their own quarries of kaolin-based clays or fireclays (chamotte) used for double firing. The raw materials are submitted to dry grinding and suitably mixed and wet.

Quick-cycle support firing is obtained via roller kilns reaching temperatures of approximately 1100 °C. After biscuit glazing, the glazed product is sintered in single-layer roller kilns at approximately 1030 °C. The resulting wall tiles have a flexural strength higher or equal to 15/ mm2 in accordance with UNI EN ISO 10545-4 and a water absorption higher than 10 %, and are rated as belonging to the BIII (GL) group according to the UNI EN 14411 standard. This class of products shows virtually no shrinkage during firing: such dimensional consistency results in extremely easy installation even when no intertile gap is required.

ADVICE ON LAYING

Our double fired tiles can be laid using either cement mortar or tile adhesives. Given their high porosity, it is advisable to let them soak for at least 8 hours in clean water and then leave them to drain before laying, even when using cement-based adhesives. They should, however, under no circumstances ever be wet before laying when using acrylic or vinyl resin based adhesives or two-component organic solvent based adhesives. When laying large size tiles it is best to adopt the two layer spreading system and, when the floor is very large, to incorporate suitable expansion joints which must not be spaced more than 4-5 linear metres apart from one another. Please do not hesitate to contact Monoceram Technical Department, for helpful advice on laying our tiles on special surfaces or in unusual ambient conditions.
