Now with even more flexibility: thanks to its sophisticated technology, the Bi-Fold Door is the ideal solution for nearly all building projects. The perfect product for private living space as a classic exterior element, as a bespoke solution for wintergardens, as a multi-functional entrance for lobbies and as noise and weather protection on balconies or for façades. The Bi-Fold Door meets every requirement.
Its core piece is the new bionicTURTLE – the multifunction insulating thermal break scores with outstanding structural and U values despite its minimal sight line of only 99mm. 35 years of expertise represent endless combination options, the slimmest sight line and perfect functionality. For the aluminium version, Solarlux also offers matching window and door systems to give the facade a uniform design. These can be, for example, fixed elements, classic turn-tilt or tilt elements, model windows, skylights or even doors.
