Precision-ground ThermoCellit® bricks feature integrated, hydrophobised stone and glass wool thermal insulation within the brick chambers. This allows energy to be stored and released with a time delay. During the hot months, residents benefit from pleasantly cool indoor temperatures, while in winter, the bricks retain solar heat absorbed during the day. In spring and autumn, the heat storage capacity is often sufficient to delay the need for heating. The quality of the indoor climate is determined by optimal values for indoor air temperature, the surface temperature of enclosing structures and humidity levels. ThermoCellit® achieves U-values as low as 0.13 / W /m2K
