Folding Sliding Door Benefits

The key benefit of aluminium folding sliding doors is that they fully retract, providing a wide open space, bringing the outside in. The doors are also an ideal solution when extra space is required as they can be used to partition large rooms into small, more comfortable, cosy rooms and when required can be opened, providing one large space. Folding sliding doors are rapidly becoming a more popular alternative to French and patio doors. A folding sliding door can offer a clear opening of 90%, as opposed to 40% with patio and French doors.

Aluminium frames are now widely used as an alternative to wood, it is stronger, can be welded, fabricated and formed with ease. Aluminium will not warp, rot or require varnishing and is easy to clean and is resistant to fire.


Rationel and Sunflex folding sliding doors are widely specified in domestic properties where rooms open out onto a garden or patio area, in swimming pools or for internal partitioning. Commercial properties such as restaurants and bars can create alfresco areas and offices and schools can benefit from the extra light created by the large windows. Folding sliding doors can be incorporated in any modern or traditional property regardless of shape or size. In addition to sliding folding doors, the company also offers curved and moving corner doors, patio doors, windows and blinds and commercial doors.

Rationel windows and doors are specified by many clients throughout Europe and products offer a comfortable indoor climate, light and superior functionality.
