Study of the oko-Institut: roof bricks are more environmentally friendly than roof roof bricks and roof tiles, the most common deck materials on German rooftops, are made differently: the roof-tile consists of clay that is fired at 1000 degrees Celsius in the oven. The roof stone, however, only about 20 percent of its mass is burned, more precisely: only the feedstock, the raw material cement. In a second step of the process, cement and sand are mixed and finally hardened in an energy-saving drying at 60 degrees Celsius. The Auditors of the oko-Institut analyzed and rated formation throughout the course of the two products. Beginning with the collection and provision of raw materials through production and packaging to transport.
While all were compared to potential adverse effects in air, water and soil. The result: In all appropriate areas, greenhouse gases, energy production, fine dust formation, load on the floors, roof bricks are more environmentally friendly. Numbers make it even clearer: A carbon dioxide contributes to the emergence of some 3,440 kg average brick roof with an area of 160 square meters roof stones are only 1,550 kilograms. You extrapolate this on all roof surfaces in Germany, as can be observed: with the invention of the roof stone, the atmosphere so far to around 20 million tonnes carbon dioxide was exonerated. In addition, that roof stones considered particularly sturdy, unbreakable and frost resistant deck material can be processed very well. The conclusion for the homeowner: With the election of Braas of roof stone everyone can make a contribution to environmental protection and must go a no compromise on quality.
