The wooden fibre insulation plates (12) are fixed onto the outside of a wall (10) by plugs (28). The plates are joined together by tongue and groove joints (30). A hydrophobic mineral coating (14), which is an integral material frame (16), is applied to the plates. This frame then receives a coating (18). The insulation plate in wooden cellulose which is usable as support filler or rendering has the following composition: 90 to 95% by weight of ligno-cellulose formed from chemically untreated wood fibres, 0.2 to 0.7 wt.% aluminium sulphate for activating the wooden fibre binder up to 2 wt.% glue, the remainder being water. The density of the plate is between 150 and 280 kg/m<3>. The plate is formed from a layer of constant density or from several layers of different density. The insulation plates have accepted insulation properties and can be used as support rendering or filler.
