Louvered doors are also known as Venetian doors. In this type of doors, the shutters are provided with louvers, either fully or partly.
Thin parallel lovers of timber, steel or glass are placed horizontally one above the other at such an inclination that the horizontal vision is obstructed. The louvers may be movable or fixed.
In the case of the louvered doors with fixed louvers, the upper back edge of any louver is kept higher than the lower front edge of the louver just above it. The louvers should always be kept sloping away from the inner side of the door so that rainwater may not enter through them.
In the case of the louvered doors with movable louvers, a verticle piece of timber is provided to which the louvers are attached through hinges. The louvers can be moved up or down with the help of the vertical piece of timber.
The louvered doors allow free passage of air when closed and at the same time maintain privacy. They are used for sanitary blocks of public buildings, residential buildings, etc. The louvered doors should be periodically cleaned.
