The UK’s Most Popular Aluminium Bi-fold System
Smart’s Visofold system is the UK’s most popular aluminium bi-fold door range, with the latest addition, the new Visofold 1000 Slim, delivering a range of benefits for the fabricator, installer, and end user. Featuring new slimmer profiles, the sightlines of Visofold 1000 have been reduced by 10mm to 122mm, to make the glazed area even larger.

Design Flexibility
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 or in the middle. 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.

For installers, the Visoglide Plus doors feature Smarts Quick-Glaze Bead technology. The integrated gaskets are simply tapped-in on site, without the need to use a wedge gasket, making the installation and glazing process faster, more straightforward and more cost effective.
New Slim Vent
Our aluminium bi-fold doors now feature the new Glazpart bi-fold vent, designed to fit neatly within the head of the door sash for a cleaner, more efficient installation. Because the vent is integrated into the sash, no knock-on or extended profiles are required, helping installers achieve a streamlined finish while reducing installation time.
Available in black, white or grey, or sprayed to match any RAL colour, the vent blends seamlessly with the door system. It provides a simple, compliant and cost-effective ventilation solution without compromising the appearance of the door.
