OUTDOOR TESTED FROST PROOF
FUNCTIONAL CERAMICS WITH MEMBRANE EFFECT
Ströher heavy clay ceramics possess “breathable” capillary channels and a “waterproof” pore structure with a draining, homogenous particle structure. So even the slightest amount of condensation can escape naturally and won’t have to force its way out of the tile. We call this the membrane effect. In transitional seasons and depending on the regional location, ceramics in outdoor areas will have to be able to withstand temperature fluctuations of up to 70°C and rapid freeze/thaw cycles. Ströher heavy clay ceramics can do this – compliant with the DIN EN ISO 10545-12 test standard, even beyond the required laboratory conditions.
WITH 25 YEARS FROST RESISTANCE GUARANTEE.
The highly structured reverse surface of the tensile heavy clay ceramics made from wet clay ensures optimal interlocking with the subsurface. This ensures optimum adhesive tensile strength. In contrast to the ‘glazed’ surface of the dry pressed body, heavy clay ceramics do not come loose even under heat stress, provided they are properly laid.
