Wooden Flush Door Parts, Body, Surface, Core, and Edging

You are familiar with a wooden flush door, and it is a simple door that is usually installed to build room partitions. It may rarely be used as the main door that divides the outside and the inside of the house because a flush door cannot stand rain and sunny day, which will cause moldy. However, its simple design makes this type of door preferable to any other door; some people choose this door because it is easily installed as the lighter version of the door does not need any professional assistance, so you can do it as a DIY project. Although you are familiar with the door, do you ever know what a wooden flush door consists of? This article will discuss the essential parts of the door and the function of each part.

Flush Door Body

The first part of a flush door and the essential part of the door is the body; the body consists of several parts, and the main function of the door is to maintain its stability. Depending on the type of door that you choose, the body of the door may consist of different parts. To build the core of the door, the artisan should use the same materials, whether they are hard or medium wood. 

Generally, the door’s body is categorized into two categories: stile and rail. Stile is the vertical body, and the wood will be as long as the door’s height. In contrast, the rail is the horizontal body. The laminating process is needed at least three times, but often more than that. The laminating process will determine the thickness of the door; the thicker they are, the more layer the door has. 

Surface

The surface of the wooden flush door is what you see on the door, and it is the entire appearance of the door that you can see with your eyes. The door’s surface is smooth and straight as the doors are mostly made from layers of plywood, so creating a heavy curved on the surface is almost impossible, to begin with. Since the doors are added from layers of wood, the thickness of the door is also varied. The least thick doors are around 3 cm thick, but they may be got thicker when additional layers are put on the surface.  

The surface will also be painted in different colors depending on the demand, but they are mostly available in neutral colors. On the surface, the factory will add the kin, which is made from wood veneer. In building the flush door, the glue will be used not only to assemble the parts but also to layered the wood surface; although the pressure technique is applied during the laminating process, glue is also essential to maintain the surface to be united. 

Core/Buffer

A wooden flush door also consists of a buffer to fill in the inside of the door; the most common buffer that you can find in a flush door is honeycomb paper as the size of the honeycomb that is used on the door is around 20 to 22 mm. however, honeycomb is not the only solution to fill in the inside of the door; some company uses PU foam because it is more durable to weather change compare to the honeycomb. While other companies may prefer to use Rockwool, styrofoam, and synthetic acrylic, which are environmental and health-friendly.

We usually find a hollow one or an empty space between the surface to save the budget, also the hardcore solid wood without empty space between the surface to make it more durable and soundproof. 

Flush Door Edging

The edging is also added to support the door; the type of edging that will be used on the door will depend on the type of material that is used on the veneer; it uses the same material to support the consistency of the door because it may give odd marks on the door in term of color and texture of the wood. 

Although the door may seem simple, it is made from parts that have been calculated beforehand to meet each function of the door. Some factories may use different materials to build the door, and others may have different regulations and procedures for producing a single door. However, most wooden flush doors consist of the same parts and divisions. The parts may be slightly different when the type of the door needs additional structure to complete its function.
