The Stowlite concrete block offers the builder an alternative product midway in the range between the dense concrete block and the high performance Fibotherm block. Stowlite blocks are widely used in a number of applications where high insulation is not such a priority. Being lighter than the standard dense block, handling is easier, often making savings on foundations and labour.
