Smart Aluminium Bifolding Doors

Our Smart Aluminium Visofold Doors are one of the most popular home improvements we offer. They bring light and space into your home with large, clear openings. Folding the individual leaves to either side saves more space than sliding patios, and allows an entire wall to be opened at once.

Our range of Aluminium Folding Doors are made from thermally-broken Smart Systems profiles. They are one of the UK’s leading architectural aluminium system suppliers. The Visofold series of bifolding doors includes versions suitable for both domestic and commercial use, with a wide and versatile range of configurations.


Our Aluminium Bi Fold doors are manufactured from slim 60mm thermally broken profiles to ensure maximum glass widths can be acheived using the minimum number of panels. This allows for more natural light and unobstructed views of the outside world. There are no additional mullions required between the panels that broaden the sight lines so when panels are folding and sliding in the same direction, the width of the aluminium from edge of glass to edge of glass is just 132mm.

Handle Options

Lever handles operate the hook bolt locking system on traffic doors and provide external key access whilst intermediate panel shoot bolt locking is operated by internal fold-flat handles as shown. Handles are available in white, chrome or black finishes but can be supplied to any RAL colour at extra cost. Please note that the style of traffic door handles will differ when RAL colour handles are specified. ‘D’ handles (black or chrome only) are fitted to the hinges of the intermediate panels to allow easy opening and closing of the bifold doors.



Low Threshold Option

The Visofold 1000 aluminium bifolding doors feature strong, durable profiles and a choice of low or weathered thresholds. The non-weathered low threshold provides the opportunity to create flush floor levels between two living spaces by sinking the threshold into the floor and merging the two floor areas into one. This is particularly useful for room dividers or for doors installed between the main house and conservatory where they are often left open most of the time.
