Impregnation and varnishing
The finished elements are transferred to the paint shop, where the windows are first impregnated with the multi-jet spray method. After drying, an interlayer is applied to protect the wood against water penetration. Once these two layers are applied, it is time for the varnish to be put under pressure. The windows then undergo another quality control, and at this stage, any imperfections are eliminated and the last irregularities are polished. Only then is the final coat of varnish applied.
