Why choose a Visofold 1000
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.

OUR BI-FOLDING DOORS
We have two bi-folding products available, the Visofold 1000 and Visofold 6000. The engineering behind the Visofold 1000 and Visofold 6000 means they can be manufactured with much larger folding panels, allowing for larger glass door panels. The Visofold 1000 offers a more cost-effective option whilst retaining many of the features found in the Visofold 1000 and Visofold 6000. All our styles make a great bi-fold patio door to bring the outside in. Take a look at our bi-folding door collection:
