Abstract

L'invention concerne un carrelage de pierre dans lequel la surface du carrelage peut être maintenue à basse température pendant une période relativement longue lorsqu'elle est aspergée avec de l'eau, notamment en été lorsque le soleil éclaire un balcon ou une terrasse pendant longtemps. L'invention concerne plus précisément un carrelage de pierre comportant des trous traversants possédant une forme allongée dans le sens de l'épaisseur de la plaque, le volume des pores formés par les trous traversants à proximité de la surface du carrelage étant plus important que le volume des pores formés par les trous traversants à proximité du centre à l'intérieur du carrelage. En outre, lorsque le carrelage est utilisé comme sol pour un balcon ou une terrasse la température de surface du carrelage peut être efficacement abaissée en arrosant le carrelage avec de l'eau, et la température de surface abaissée peut être maintenue pendant une longue durée même en été lorsque la température de surface peut atteindre 50°C ou plus.
