Flush door installation and its rate analysis

Doors are a vital part of any building facility. They provide safety, security and privacy. Hence it becomes important to have strong and durable doors. Interiors of a living space can be bolstered by adequately sized door panels. There are many types of doors available-

• Wooden
• Toughened glass
• Aluminium
• Mild Steel, etc.

Flush door is a simple board door panel that is built of a solid core enclosed within a layer of veneers on both sides. The outer frame is made up of solid continuous wood of at least 2” thickness that runs around the perimeter of the door panel. The inner core is made up of blockboard wood panels/ particle board. Its quality governed by IS Code 2202-1 (1999). Depending upon the concentration of the core material, it is categorized as listed below-

• Hollow core type
• Cellular core type
• Solid core type

At either end of the door along the middle of the length, we have solid wooden blocks so as to enable the installation of bolts and inter-lock, which if not present would eventually lead to the disintegration of the door. The wood used in the manufacture of the flush door must be properly seasoned, chemically treated so as to avert termite invasion and bending/ warping on account of temperature changes.
