Groundbreaking avante-garde folding sliding doors

The technology and design of Dutemann FD85 bifolds is a result of years of planning design and execution. Where standard openings call for three panels in other brands, these doors only need two, four becomes three, five becomes four.  You benefit from sliding-door sized panels with closed doors and the desirable functionality associated with a bifold. Sightlines of 105mm with a fresh flat aesthetic make these the thinnest aluminium bifolds on the market yet also coming at remarkable panel sizes of 1.35m wide. At the same time, these doors have formidable strength, durability and performance. Extensively tested and expertly-made, these are futuristic folding sliding doors.

Made to Measure

Perfectly suited for your home or extension

A perfect combination of latest-generation insulated aluminium and professionally applied powder coated colours creates visually appealing bifolds whether open or closed.  Multiple configurations and opening options with quality safety glass complete your look.

Custom-built bifolding doors

The durable powder-coated finishes protect the aluminium and add a modern look in your home.  Over 150 different colours let your imagination run free.  For even more choice, there are metallic and textured colours, anodised, matt or gloss shades too. Low maintenance colours that only need an occasional clean to look good for years. The handles and hinges also give you matching or contrasting colour options for these extraordinary bifolding doors.  You can then choose the right glass to meet your needs. Laminated for extra security, acoustic for a quieter home, triple glazing and even glass with built-in manual or electric blinds. Every door comes built to your sizes, colour, configuration and specification.
