Here is an oak french window on the floor of the workshop in 2004. The raised and fielded panels have been prefinished to avoid the appearance of white lines at the edges due to seasonal movement. The glazing bars have no rebates to allow a single, double glazed unit to be used instead of six. An external 'grille' is made to match precisely the arrangement of the bars inside. The thinking behind this is that, with the grille removed, it will much easier to clean the glass and maintain the woodwork, and has the added benefit that there are far fewer edges to lose heat through.
