Bi-Folding Doors

Bi-Folding Doors

Available in a range of opening configurations to suit any application, Visofold doors can be folded internally or externally and with the opening at the side (so the sashes all fold one way), at one end (to create a single entrance door) or in the middle (to give the option of a double door).

Visofold’s flexibility makes it the ideal choice for projects where large, uninterrupted openings are required, with the system providing maximum light and space to give unimpeded views.

The highly-versatile, easy-to-operate system is the perfect option for even the largest project, capable of opening up an entire wall, yet presenting a contemporary, elegant glazed façade when closed.

Visofold 1000 profiles feature a thermal break to deliver enhanced thermal performance and energy efficiency and security is assured by multi-point lock mechanisms on the main opening sashes, and shoot-bolt locks on the ‘floating’ mullions.

The doors can have either a low threshold for unimpeded access, or a rebated threshold for improved weather resistance.

Visofold 1000 doors are available in a choice of standard or non-standard colours, including metallic, dual colour and unique Sensations range of textured finishes.

Our systems have been designed to
not only withstand all that the elements can throw at them,
but also to deliver minimum heat loss and great thermal efficiency.


Kitemarked and security-tested to the PAS24 standard, Visofold 1000 slide-folding doors features a choice of internally or externally folding panels, which when open help to integrate the home’s external and internal living spaces, offering uninterrupted views.
