LECAT Block accommodates less water than other blocks due to the structure of the clay ball. (Between 15%-20%) This ratio is in the range of 60-70% in brick, 70-80% in bims block, 80-90% in gas concrete. With this aspect, because it does not keep the water in its body over the years it does not lose its feature , since its thermal conductivity coefficients are low, its insulation values are high. Sound insulation is 48.7 decibels.
