lose encore appelées plaques d'isolation à fibres de bois; il s'agit de plaques de fibres, souples, fabriquées par un procédé par voie sèche ou par voie humide, consistant à mettre en forme la matière fibreuse et le cas échéant à la sécher. De telles plaques d'isolation sont utilisées dans la construction pour assurer une isolation phonique et thermique.10 Il est en outre connu d'utiliser des plaques de laine ou de paille de bois comme supports pour des crépis. Pour l'utilisation comme support de crépi on mélange la laine de bois à des liants minéraux comme par exemple de la magnésite, du ciment, du gips ou des matières analogues. L'adjonction de lose also called wood fiber insulation boards; these are flexible fiber boards, manufactured by a dry or wet process, consisting of shaping the fibrous material and, if necessary, drying it. Such insulation plates are used in construction to provide sound and thermal insulation.10 It is also known to use wool or wood straw plates as supports for plasters. For use as a plaster support, wood wool is mixed with mineral binders such as, for example, magnesite, cement, gips or similar materials. The addition of

In addition, such an insulation plate is used as a plaster or plaster support. The plaster can be applied directly to the insulating plate so that when a suitable mineral plaster is used, respiratory activity is effectively retained even when the

Similarly, the elimination of the insulation plates and the residues from cutting the plates do not create any ecological problem. 5 When the insulation plates consist of several layers as this is advantageous for different

Dans le cas des constructions en colombage, la plaque d'isolation peut servir au remplissage du colombage most different applications. The insulation plate can be used as a facade cladding plate on all types of walls. In the case of a wooden frame with a load-bearing covering, the insulation plate can be used as a plaster support plate.
