Many people are familiar with sliding doors, while swinging doors—often called "hanging and sliding" doors—are relatively unfamiliar. When it comes to purchasing these types of doors, most customers aren’t entirely clear about the differences between them. In fact, some buyers can’t even tell the difference between hanging and sliding doors. Today, our editor will walk you through everything you need to know about hanging and sliding doors, highlighting exactly how they differ.
Overview of Sliding Doors and Swing Doors
1. Sliding door
Sliding doors are supported primarily by lower-mounted rollers that glide along an underground track, allowing the door to slide smoothly from side to side. The main point of load-bearing is on the bottom rollers, while the top rollers usually serve as auxiliary guides. As a result, the quality of the floor track and bottom rollers directly determines the lifespan of the sliding door. Traditionally, sliding doors were most commonly used in bedroom walk-in closets and as wardrobe doors. However, with advancements in technology and the growing diversity of interior design options, sliding doors have evolved significantly—ranging from enhanced surface treatments of the door profiles to a wider variety of glass options and state-of-the-art hardware components. This evolution has steadily expanded both the functionality and application scope of sliding doors. Today, beyond their typical use as room dividers, sliding doors are increasingly popular in living rooms, kitchens, bookcases, built-in wardrobes, and even as entrance doors for many luxury villas.
2. Sliding Door
A sliding door system features an upper suspension wheel for support and a lower track-mounted roller for precise positioning, allowing the door to slide smoothly left and right. The primary load-bearing component is the aluminum alloy upper track, and the quality of the suspension wheel directly influences the lifespan of the sliding door. These doors are ideal for use as partitions in areas such as balconies, dining rooms, kitchens, and even bathrooms.
The Difference Between Sliding Doors and Swing Doors
Sliding doors feature an upper rail and a lower track, with concealed wheels installed beneath the door for smooth sliding motion. Because the weight of the door is concentrated at the bottom, these types of doors are easy to install and simple to maintain. However, the lower track tends to accumulate water and trap dirt, making cleaning a bit more challenging.
A sliding door features an overhead track with hanging rollers for smooth, effortless movement, while a single guide wheel at the bottom ensures water doesn’t pool or dirt accumulates—making cleaning even easier. Plus, this type of door opens silently and eliminates the need for a threshold, offering a sleek, elegant, and sophisticated look. However, compared to sliding doors, it has a slightly shorter lifespan and lower resistance to impacts.
These two types of doors each have their own advantages and disadvantages, so customers can choose based on their specific circumstances.
