METHOD FOR MANUFACTURING A ROOF-COVERING ELEMENT MADE OF PLANT FIBRES, AND ROOF-COVERING ELEMENT

摘要

The invention relates to a method for manufacturing a covering element made of moulded cellulose impregnated with roofing bitumen. In a first step, an element, preferably made of cellulose, is manufactured by means of hot-pressing in a mould; in a second step, when the element has a dry matter content of at least 60% upon removal from the mould, said element is covered with pigmented varnish and dried; and in a third step, when the element has a dry matter content of at least 98%, said element is impregnated with a hot bitumen. Specific operational conditions are indicated. The covering elements include, in particular, a side ridge portion, a ridge cap, a ridge kit, a cant strip or skylight frame and a hip rafter.
