Top-Hung vs Bottom-Rolling Patio Doors: Which Is Right for You?

How They Work:
In a top-hung system, the door is suspended from hangers which run in top track and take the weight of the system, while the bottom track typically serves as a guide rather than bearing the door’s weight.

Pros:

Smoother Operation:
Because the weight is supported from above, these doors often glide more smoothly and quietly than bottom-rolling systems.

Modern Aesthetic:
Top-hung systems offer a sleeker look, often appearing more "frameless" or minimalist, which is great for contemporary designs.

Less Maintenance Required:
Debris is less likely to collect in the top track, meaning the doors are less likely to jam or stick.

Cons:

Structural Requirements:
A strong overhead support beam is needed to carry the weight of the door, which may not be feasible in all homes (such as conservatories and orangeries).

Higher Installation Cost:
Installation can be more complex and costly, especially if retrofitting into an existing structure.

Our Soltaire sliding door hardware offers a top hung system which takes the weight of the doors from above. Catering for wooden and metal doors weighing up to 250kg each, Soltaire is an extremely high performing and robust system.

How They Work:
Bottom rolling systems work with rollers which are fitted to the bottom of the door and slide along a rail on the floor track that supports the full weight of the system. The top track helps guide the movement but doesn’t bear the weight of the doors.

Pros:

No Overhead Reinforcement Needed:
Because the door’s weight is supported by the floor, there’s less structural support required above the opening.

Easier Installation:
Bottom-rolling doors can be simpler and less expensive to install, especially in older homes or during renovations.

Cons:

Maintenance Required:
The bottom track can collect dirt, stones, and other debris, leading to jamming or operational issues if not cleaned regularly.

Slightly Noisier:
These doors may not glide as quietly or smoothly as top-hung options, especially if the rollers wear out.

More Traditional Appearance:
Depending on the design, bottom-rolling systems may appear bulkier or more conventional.
