Minimalistic Windows

The perfect synthesis of design, function, quality,
Energy saving and long service life.


The minimalistic window with only 70 mm construction depth (sash 80 mm). The frame/sash combination has a view height of at least 95/92 mm (outside/inside). The window is equally suitable for the use of double and triple glazing both in new buildings and for renovations up to 48/58 mm glass thickness.

A stable profile system with exclusively high-quality aluminium die-casted cleats for corner- and T-connectors guarantees perfect fit and the realization of large and heavy elements. Insulating bars and gaskets in VENTURA Low Lambda Technology (LLT) enable very low Uf values.

VENTURA V70 VV Ventilation Vent – motorized with concealed fittings

The VENTURA V70 VV is used for natural ventilation and SHEV systems. Basically, no fittings are visible. The 24V motors from German production can be inserted into the narrowest profile geometry. The center gasket level remains fully intact – the window is tight.

Professional window technology requires VENTURA components

The VENTURA V70 window achieves extreme tightness through the use of high-quality gaskets and fittings from Germany. Tested and certified with very good results at the Institute of Window Technology (Institut für Fenstertechnik – ift) in Rosenheim.

Calculation of Uf values by BAUWERK, Rosenheim (BFRC Certified Simulator)
  • Uf = 1,3 -1,4 W/m2K
  • Uw = < 1.19 W/m2K for double glass with Ug = 1.0 W/m2K and Swiss Spacer Advance
  • Uw = < 0,80 W/m2K for triple glass with Ug = 0.5 W/m2K and Swiss Spacer Ultimate

All calculated Uw values in the smallest profile combination with 95 mm view height in the standard size of outer frame WxH 1,230 x 1,480 mm.
Even smaller Uw values for larger elements.

Outer frame / sash section 2-glass 24 mm

Outer frame / sash section 3-glass 36 mm

Mullion 76/26 with 35 mm reinforcement / fixed glass

Mullion 84/34 with 70 mm reinforcement / double sash

Standard systems primarily increase frame insulation (Uf values) at the expense of ever greater construction depths by using ever wider insulating bars in mainly PA 66 material. Disadvantages of this development are increasing tolerances and the resulting lack of plan parallelism of the profiles, unclean mitres and leaks.

VENTURA uses higher-quality materials in LLT insulating bars with 40% lower Lambda values. The short 34 mm insulating bars provide a stable frame construction with only 70 mm construction depth.

VENTURA V70 achieves excellent insulation values in combination with LLT gaskets and this with a low viewing height of the glare frame / sash combination of only 95 mm.

VENTURA coined the term “Green Building Excellence” as a new ecological environmental standard. The low use of materials in each VENTURA system conserves natural resources, the excellent insulation minimizes energy consumption down to the passive house standard and the outstanding quality ensures a long service life.
