Wood cladding for mounting on the inner surface of nonwooden windows having common interior cross sections in which the sash is mounted on the frame from the outside of the window, the windows including a frame having a substantially planar inner surface with a screen recess disposable in the interior of a building, an outer surface opposite the inner surface and disposable on the exterior of the building, an exterior side surface between the inner and outer surfaces mountable inside a wall of the building, and an interior side surface between the inner and outer surfaces for receiving a sash, and a sash having a substantially planar inner surface disposable in the interior of the building, an outer surface opposite the inner surface and disposable on the exterior of the building, an exterior side surface between the inner and outer surfaces and receivable in the interior side surface of the frame, and an interior side surface between the inner and outer surfaces for receiving a pane of glass, said wood cladding comprising:

• first and second sections of wood shaped to conform to the inner surface of the window, each said wood section having a uniform cross section along its entire length, being attachable to both the frame and the sash of the window without substantially altering the length and width dimensions of the window or affecting the fit of the window within a wall opening, said wood cladding providing an unmarred, unblemished wood appearance on the inner surface of the window;
• said first wood section being mountable on the inner and interior side surfaces only of the frame of the window and having a uniform cross section conforming to the shape of the frame, said first wood section comprising a frame body portion disposed against the substantially planar inner surface of the window frame, a frame retaining lip disposed on one end of said frame body portion, said frame retaining lip being substantially perpendicular to said frame body portion and fitting around an outer peripheral edge of the substantially planar inner surface of the window frame, and a zig-zag portion disposed on the other end of said frame body portion and conforming to the screen recess formed on the substantially planar inner surface of the window frame, the outer surface portion of said frame zigzag portion being capable of receiving window screens;
• said second wood section being mountable on the inner and interior side surfaces only of the sash of the window and having a uniform cross section conforming to the shape of the sash, said second wood section being L-shaped and comprising a sash body portion disposed against the substantially planar inner surface of the window sash, and a sash side portion disposed on one end of said sash body portion, said sash side portion being substantially perpendicular to said sash body portion and fitting against the interior side surface of the sash;
• and
• fastening means for fastening said wood first and second sections to the nonwooden window without being visible on the exterior of said wood sections.
