Venetian Window

A Venetian blind has horizontal slats, one above another. Venetian blinds are basic slatted blinds made of metal or plastic; wooden slats are sometimes used but in the US these are now usually referred to as wood blinds or bamboo blinds. They are suspended by strips of cloth called tapes, or by cords, by which all slats in unison can be rotated through nearly 180 degrees. The slats can be rotated such that they overlap with one side facing inward and then in the opposite direction such that they overlap with the other side facing inward. Between those extremes, various degrees of separation may be effected between the slats by varying the rotation. There are also lift cords passing through slots in each slat. When these cords are pulled, the bottom of the blind moves upward causing the lowest slats to press the underside of the next highest slat as the blind is raised. A modern variation of the lift cords combines them with the rotational cords in slots on the two edges of each slat. This avoids the slots otherwise required to allow a slat to rotate despite a lift cord passing through it, thus decreasing the amount of light passing through a closed blind. Slat width can be between 16–120 mm, with 25 mm being a common width.

Fully Paneled Door

Panel doors, also called stile and rail doors, are built with frame and panel construction. EN 12519 is describing the terms which are officially used in European Member States. The main parts are listed below:

  • Stiles – Vertical boards that run the full height of a door and compose its right and left edges. The hinges are mounted to the fixed side (known as the “hanging stile”), and the handle, lock, bolt, and/or latch are mounted on the swinging side (known as the “latch stile”).
  • Rails – Horizontal boards at the top, bottom, and optionally in the middle of a door that join the two stiles and split the door into two or more rows of panels. The “top rail” and “bottom rail” are named for their positions. The bottom rail is also known as “kick rail”. A middle rail at the height of the bolt is known as the “lock rail”, other middle rails are commonly known as “cross rails”.
  • Mullions – Smaller optional vertical boards that run between two rails, and split the door into two or more columns of panels, the term is used sometimes for verticals in doors, but more often (UK and Australia) it refers to verticals in windows.
  • Muntin – Optional vertical members that divide the door into smaller panels.
  • Panels – Large, wider boards used to fill the space between the stiles, rails, and mullions. The panels typically fit into grooves in the other pieces, and help to keep the door rigid. Panels may be flat, or in raised panel designs. Can be glued in or stay as a floating panel.
  • Light or Lite – a piece of glass used in place of a panel, essentially giving the door a window.
