Outside door, has chemically or thermally modified pinewood planks or panels held in frame assembled from wooden jambs and sills

摘要

The door has two wooden jambs on opposite vertical sides and top and bottom sills made from wood extend between these two jambs to form a frame. All or some of the space inside the frame, preferably only the lower half of this space, is filled by a wooden panel and/or plank material. The jambs and sills all have a single-piece construction. The wood for the frame and/or filling comprises chemically or thermally modified pinewood, which can optionally be laminated and/or finger-jointed.
