What customisation options are available?
The Visofold 1000 Slim can be customised with various finishes, including metallic, woodgrain foils, and dual colour options. A range of hardware choices is available, including bespoke painted accessories to match or contrast with the colour of the doors. We also offer a lock mechanism with a domestic style ‘lift-up’ handle and an adjustable, one-piece keep.
What configurations are available for the Visofold 1000 Slim?
The Visofold 1000 Slim bifold door offers a variety of configurations to accommodate different design and functional needs. The doors can be configured to fold either internally or externally, allowing for flexibility depending on the space available and the desired opening style. The system can have the sashes fold to one side or be split to open from the centre, creating a double-door effect. This allows for different entry and exit points, which can be tailored to the user’s preference or the specific layout of the property.
The doors can be customised with various numbers of panels to suit the size of the opening. Configurations with up to seven panels are available, with a maximum width per panel of 1200mm, allowing for expansive openings that can enhance the indoor-outdoor living experience. Additionally, there are options for low thresholds for easy access, which is particularly useful where wheelchair access is needed, or rebated thresholds for enhanced weather resistance.
Can the Visofold 1000 Slim be used in both residential and commercial settings?
Yes, the Visofold 1000 Slim is suitable for both residential and light commercial applications. It can be used as an alternative to sliding doors in homes, incorporated into conservatories, or installed in commercial spaces like bars, cafes, and restaurants. This flexibility makes it a popular choice for creating seamless transitions between indoor and outdoor areas.
