"Spectacular Installation"
"Looks Stunning"


Use Visofold as 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.

With Visofold, create a glazed screen that brings maximum light to a room and also easily glide to open up an entire wall.

Visofold doors offer a choice of opening configurations to suit any application:

Choose to fold the sashes internally or externally. Choose to place the opening at the side so the sashes all fold one way to one end, which creates a single entrance door for easy access. Or choose a middle opening to give the option of a double door.
