• the pieces of wood used generally have a rectangular or square cross section.
• this second type of panel consists of 5 to 7 layers of wooden boards.
• Such an assembly makes it possible to cumulate the properties of the layers of wood blades.
• the wood strips do not need to have a cross section too large to ensure the mechanical strength of the building.
• the amount of material necessary for the realization of such panels is still important, equal to the volume of the panel.
• first type and second type of panels also have the disadvantage of creating significant material falls during cutting to make openings such as windows and doors.

• - wooden boards of a layer of wooden boards are positioned, parallel and in the same plane, in the same orientation, with a spacing between the longitudinal axes of two consecutive wood blades, the center distance being substantially equal to twice the average width of the wood slats and thus defining an interval between the consecutive wood slats of the layer
• - layers of non-joined wood slats are superimposed so as to have two perpendicular orientations and in such a way as to intersect the wood slats with a layer of non-joined wood planks with respect to the wood slats of adjacent layers with non-joined wood slats, in which: - the non-joined wood slats 'a layer are shifted transversely, relative to the wooden blades of the consecutive layers with the same orientation, a distance substantially equal to the average width wooden boards,

• the cross section of the wood slats has a central symmetry. Such central symmetry promotes the extraction or embedment of a wooden blade between two adjacent blades if necessary, by rotation about the longitudinal axis of symmetry. Maintenance is simplified.

• the mechanical fixing means may be pegs and / or glue and / or nails and / or screws.
