A door may be an entrance, exit, or a combination of these. It is often framed with wood or iron. Doors move in various ways, from sliding along a parallel plane to folding at an angle. They can also rotate around a central axis. Several secondary functions of doors are to separate rooms or functions, control airflow and ventilation, block the spread of fire, and even allow for light to enter a room.
A door is made of three basic components: its surface veneer, its inner structure, and its frame. The material used for a door will vary depending on the style and the type of construction. Solid wood doors are generally considered the highest quality. However, these are not the only type of doors on the market. Some are made of engineered wood products (MDF) and are molded into paneled designs. Compared to hollow core doors, solid core doors weigh more and are more expensive than their hollow counterparts. The traditional styled door usually consists of four or six panels separated by stiles and rails. Unlike modern doors, solid wood is much more prone to expanding and contracting with the changes in humidity.
Exterior solid wood doors are made of solid wood components and are among the most expensive types of doors. Fiberglass is a relatively new construction material made from plastic or glass fibers. Because of its lightweight properties, fiberglass doors are durable and energy-efficient. They can also be a great option if you are on a budget. For a more contemporary style, choose one that blends aesthetics with performance. These types of doors are often considered the most attractive.
