Thatching material is a type of roofing material used to protect buildings from the elements. It is made up of various materials, including reeds, STRAW, and REED. Reeds are long, thin, hollow stems of grasses that are bundled together and used as a roofing material. STRAW is a by-product of grain production and is also used as a roofing material. REED is a type of grass that is dried and used as a roofing material. All three materials are commonly used in thatching material and provide a durable and attractive roofing solution.
