Visofold 4000 Patio Door

Unique slide and fold dual hollow aluminium system. The doors which sit in a rebated frame have an external curved shape with internal beading. Bottom wheels and top glider are safely concealed within a dedicated floating mullion with the door leafs being joined by a butt type knuckle hinge. Suitable for domestic and light / medium / heavy duty commercial applications.

Visofold can be used in domestic applications as either an alternative to sliding doors, or to open up an entire wall as part of a conservatory; the system will make the most of a beautiful view or bring a garden into the home.

Used commercially in a bar, café or restaurant, Visofold can create a glazed screen that allows in the maximum ingress of light in inclement weather, and will also easily glide to open up an entire wall in warmer weather. Visofold doors offer a choice of opening configurations to suit any application. Choose to fold the sashes internally or externally, place the opening at the side so the sashes all fold one way, at one end, to create a single entrance door for easy access, or in the middle to give the option of a double door.
