Sliding doors move horizontally on tracks, while stacking doors consist of multiple panels that stack together when opened.
What are sliding doors?
Sliding doors are typically made up of large glass panels that move horizontally along tracks. They are designed to either slide over another panel or into a pocket in the wall. Here are some key features:
- Mechanism: These doors use rollers and tracks for smooth movement. The rollers are mounted on the bottom of the door, allowing it to glide effortlessly.
- Design: Sliding doors often provide a wide and unobstructed view, especially when made with large transparent glass panels. This design makes them popular for locations with scenic views or in homes aiming for a modern aesthetic.
- Usage: They are commonly found in patios, balconies, and certain indoor spaces like walk-in closets or as room dividers. Given their design, they’re a favorite for areas where space-saving is crucial.
- Varieties: Over the years, different types of sliding doors have emerged, including bypass doors, arcadia doors, and pocket doors.
What are stacking doors?
Stacking doors, also known as “stacker doors,” consist of multiple panels that slide and stack behind one fixed panel or slide and fold, stacking to the side. Some of their features include:
- Mechanism: The stacking mechanism means each door panel stacks behind the previous one, allowing for a wider opening than traditional sliding doors.
- Design: The series of door panels can create a sort of concertina effect when they are fully opened, maximizing the connection between indoors and outdoors.
- Usage: These doors are often used in homes or commercial settings to open up large portions of a wall, making them ideal for merging indoor and outdoor living spaces. They can be seen in beachfront properties, resorts, or restaurants with al fresco dining areas.
- Varieties: Stacking doors may differ in the number of panels and the way they are configured to stack. Some well-known types include bi-fold doors and multi-slide doors.
Design and Mechanism
How sliding doors work
Sliding doors operate using a simple yet effective mechanism that allows them to glide horizontally. Here are the essential components and how they work:
- Tracks and Rollers: At the core of their operation, sliding doors utilize tracks usually positioned both at the top and bottom. The door panels have rollers attached to their bottom, which move along these tracks. This configuration allows for a smooth sliding motion.
- Frame and Glass Panel: Typically, the door consists of a robust frame, often made of aluminum, wood, or vinyl, housing a large glass panel. This design allows for maximum natural light and visibility.
- Lock Mechanism: Most sliding doors come with a latch-style lock, though many homeowners choose to add additional bar or rod locks for increased security.
- Weather Stripping: To protect against drafts, rain, and pests, sliding doors usually have weather stripping along the frame. This provides a tight seal when the door is in the closed position.
How stacking doors function
Stacking doors, often seen as an evolution of the sliding door concept, operate by sliding multiple panels in a cascading fashion. Here’s how their mechanism works:
- Multiple Tracks: Unlike the standard two-track system for sliding doors, stacking doors may utilize multiple tracks. This design allows each door panel to have its own dedicated track, facilitating the stacking process.
- Stacking Process: When opened, the first door panel slides, followed by the subsequent panels. As each panel moves, it stacks behind the previous one, thus creating a wide open space without obstructions.
- Locking Mechanisms: Stacking doors often employ a multi-point locking system. This means there are several locking points along the door’s height, ensuring better security compared to a single lock point.
- Seal and Weatherproofing: Just like sliding doors, stacking doors also come equipped with weather stripping to ensure no drafts, moisture, or pests can infiltrate the indoors when the doors are closed. Some advanced stacking doors also incorporate brush seals to enhance this protective feature.
