The body of rules and regulations applying to thatching is the „Fachregel für Dachdeckung mit Reet” (The Rules for Reed Thatching) which has been developed and published by the German Confederation of Skilled Crafts / Professional Association of the „DACH-, WAND- UND ABDICHTUNGSTECHNIK – E.V.” The data sheet on reed, which has also been developed and published by this central association, defines dimensions, standards and tests for the building material reed.
