INTRODUCTION :

Doors are necessary for access, safety and privacy whereas windows are provided for light and ventilation and add to aesthetic view of the building.

DOOR FRAMES

Door frames are required for the proper fixity and hinge action of the shutter. Door frames contribute sturdiness and safety to the door opening. The frame also helps in making the locking arrangement.

Since the serviceability of the shutter depends on the straightness & verticality of the frame, maximum care shall be taken while selecting the material for the frame. Usually seasoned teakwood frames are preferred because of versatile properties of wood. But to safeguard the environmental interest & cost, other material like mild steel or natural stones are preferred in this era.

While selecting the material for doorframe; following qualities shall be governed: –

1. The sturdiness of the frame through selecting proper cross-section and thickness (in case of sheet metal).
2. The serviceability of the shutter is satisfactory if the member of the frame is straight & free from faults.
3. The dead load of the frame shall not be excessive so as to hamper the verticality (plumb) and right angle of the frame.
4. Overall durability, ease in painting and maintenance shall also be considered
