THE NEW FD85®

The FD85® represents the completion of three-year project and the third product Dutemänn has brought to market with its aluminium extruder partner Alumil.

The FD85® project had three main design briefs, the product had to have market leading U-values, Innovation it had to move the bi-fold market forward and it had to meet all industry security standards.

The FD85® is a feature packed Bi-folding door system that is aimed at the more discerning home owner, architect or builder. These end users will be able to specify FD85® though our nationwide network of approved partners. Whether the end client wants great U-Values, great security or great innovation the FD85® has it all.

There has been great industry interest in the Quad-bolt™ system which is standard on and exclusive to the FD85®. Quad-bolt™ is one of the design features that both Alumil and Dutemänn are most proud of, this innovation will give end clients everywhere the added security they crave.

Initial field trials suggest that FD85® will be the “fitters friend” with its easy fit outer frames along with hinge and lock adjustment. The outer frame has been designed with corner setting blocks for quick, efficient and trouble free installation. Once the frame is in place it is a simple matter of installing the panels and glazing.
