3-pane window, 3 tilt and turn in Rehau Geneo

GENEO is Rehau's other uPVC window system, with a core of glass-fibre reinforced plastic — Rehau calls it RAU-FIPRO — instead of the usual steel reinforcing sections in the chambers. That makes the profile just as stiff at 86 mm frame depth, and with Uf 0.86 W/m²K (version with thermal modules) it insulates better than any other uPVC profile we offer. The profile has 6 chambers, takes glass up to 53 mm and has been tested up to burglar resistance class RC3. The face of frame and sash together runs from 99 to 179 mm, and 110 to 214 mm on a French casement (figures given by Janwillem on 14 September 2026 from the Rehau data sheet).

Rehau's uPVC window with a glass-fibre core: 86 mm and Uf 0.86 W/m²K.

No pane stays fixed here: all three parts of this wide window turn and tilt.

Of the four 3-pane windows, this is the form with the most hardware: three complete sets of hinges, tilt mechanism and handle. In return, every pane can be ventilated separately and cleaned from inside, with no fixed glass anywhere that has to be done from outside. That makes this form a good fit for a room that needs a lot of air, or where none of the panes can be reached from outside.

The standard size is 2,400 × 1,500 mm, split equally between the three panes. If you'd rather have one unbroken stretch of view and less ventilation is enough, the 3-pane window with one tilt and turn sash and the 3-pane window with two tilt and turn sashes are the cheaper steps in between in the same width.
