The invention relates to a method for making panels of an expanded renewable material, essentially starch, characterised in that it comprises the successive following steps: extruding unit members or strings having a small section and a substantial length <u>L</u>; assembling by juxtaposing and gluing these strings thus obtained along their longitudinal axis in order to produce a layer having a width A; superimposing and assembling by gluing at least two of said string layers in order to produce a block having a height <u>B</u> and a length <u>L</u>, said block thus exhibiting a section with a side <u>A</u> and a side <u>B</u> having dimensions related to the number of assembled unit members; and cutting said block transversally relative to the longitudinal axis along a length <u>l</u> in order to obtain plates having a maximal section of <u>A</u> x <u>B</u> with a selected thickness <u>l</u>. The invention also relates to a related device. |
