Aluminium bi-fold doors are folding glazed doors that open by stacking panels neatly to one or both sides.
Available in a range of opening configurations to suit any application, the Visofold Slim 6000 Bi-Fold Doors can be folded internally or externally, to deliver a large, uninterrupted opening. This is an even slimmer-framed version of the Smart 1000 Visofold Bi-Fold Door.
It’s a flexible system which makes it the desirable choice for not only residential projects, but for light commercial projects too.
With its slender, clean lines, Visofold Slim 6000 provides maximum light and space, affording unimpeded glazed vistas, framed within a contemporary aesthetic.
Standard, or powder-coated in any RAL colour
Our Visofold range comes in four standard colours:
Or you can choose to have these doors in any RAL colour, and you can also specify having a dual colour, allowing for a colour outside and perhaps a white finish inside.
Dual-colour is a popular choice and reflects traditional frames where the outside is painted a different colour to the interior, allowing for greater flexibility in interior decorating.
Note: paint surcharge applies for non-standard RAL colours.
Your choice of hardware is an important one as it will have a significant effect on the overall look of your new doors.
We supply a wide range of high-quality options, from the contemporary stainless steel of our new Quantum range to more retro designs, all of which can be supplied in either matching or contrasting colours to your door frames, depending on the look you want to create.
