The wall mounting of the Boiserie is made by fixing the column with some special tongue pieces; while the fixing of the other elements is tongue and groove realised.
The tongue pieces allow, among the rest, to keep a 6mm. distance from the wall itself; thus allowing, together with some non-visible holes, a recicle of air, or possible humidity.
Moreover, one can apply a simple and properly sectioned 38mm board between the columns in order to give a personal refinement touch.
