Slotted insulated light concrete masonry building block - has alternate double or triple cross stem rows along length

摘要

Max. heat insulation effect, combined with adequate rigidly, is provided by the building block for walls. This is in the form of a slitted block, of light concrete. Two or three rows of cross stem pieces alternately are incorporated over the whole wall thickness, along the block's length. Heat penetration resistance is pref. identical in the abutting sides area in the centre. The slit width may be such that virtually no mortar penetrates, in the course of stone working.
