what is thatching
Thatching is the craft of building a roof with dry vegetation such as straw, water reed, sedge (Cladium mariscus), rushes, or heather, layering the vegetation so as to shed water away from the inner roof. It is a very old roofing method and has been used in both tropical and temperate climates.hatching methods have traditionally been passed down from generation to generation, and numerous descriptions of the materials and methods used in Europe over the past three centuries survive in archives and early publications.
