ABSTRACT:
A brick which can be laid with other similar bricks for forming a heat-insulating masonry work structure. The brick includes a plurality of webs defining empty inner cavities therebetween, the cavities having heat-insulating properties and further defining inner surfaces and a width of more than 8 mm. A heat-reflecting coating is disposed on the inner surfaces of the cavities. The masonry work structure may include a brick laying material for laying the bricks such that the bricks do not fill with the material and do not clog up with dirt, the brick laying material including one of bonding mortar, thin-bed mortar, mid-bed mortar and fibrous mortar. The coating may be applied to the inner surfaces of the cavities by one of vapor deposition, spraying and bonding on as a thin film, and may further be fired. The coating may further be sprayed, coextruded and spread and thereafter fired. The brick may be produced either by applying a glaze on the inner surfaces of the cavities as a base for the coating and thereafter applying the coating on the glaze, or by admixing a water-soluble component with a raw material clay for forming a brick mixture, forming the brick mixture into a brick shape and thereafter effecting a migration of the component onto the inner surfaces of the cavities by drying and firing the brick shape.
