Award-winning world first - high-end design in aluminium

The ONE Product family

One family, one unit. ONE is harmonised and offers all common opening variants - windows, patio doors, Fixed Parts and sliding doors.

Design line Avantgarde

Everything fits together

ONE is perfectly matched. A product family of windows, sliding doors, fixed elements, interior doors, insect screens and handles.

Minimalistically slim

All elements of various opening types and functions - such as fixed units, windows and sliding doors have a uniform frame look of only 5 cm - on all sides, outside as well as inside.

Uncompromisingly symmetrical

Inspired by the look of a picture frame - equally narrow on all four sides and not dominant in any way, but restrained in its effect, the ONE is the only window and sliding door system of its type with uncompromising symmetry.

Maximum freedom in choice of material

In addition to the elegant and proven Josko wood surfaces in wild oak, oak, spruce and larch, walnut, glass, brushed aluminium and genuine steel are also possible for ONE App. This enables ONE App to perfectly match almost any style of living.

Exceptionally beautiful combination

Since we develop and produce our products ourselves we are very demanding in being able to combine the new with successful products. This allows the ONE also to be combined with frameless FixFrame all-glass systems and thereby achieve aesthetic beauty that is hard to overestimate.

Suitable for seating niches

Seating niches are new It-pieces, because they combine living comfort with a breathtaking view. This new living trend is set centre stage with the ONE and skilfully reflects the framework concept.

Deep symmetry with all elements

Unlike conventional windows, ONE does not allow the glass planes to intersect between openable and fixed units. In addition, ONE has only a very small recess to the glass outside and inside.

Symmetry in multi-part elements

The continuous, slim symmetry of ONE is also evident in multi-part window and door elements. The picture frame optics typical for ONE are preserved: The division is exactly in the middle. Each sash is completely symmetrical, both inside and outside.

Windows & patio doors

Windows & patio doors

ONE has brought back the slim elegance of the windows: with modern triple glazing and thermal insulation ratings, which are suitable for passive homes - but with the minimal frame view of earlier architectural epochs.

This is the end of the period when the design of windows and doors had to subordinate to the function and the frame widths were different.
 

Details matter

A WINDOW SILL WITH A SENSE OF SYMMETRY

The beauty of the symmetry of ONE with the design window ALU DS2 fascinates at first glance. The designer window sill maintains all-round lean frame look of the ONE.

Design window sill

The design window sill retains not only the ONE symmetry. It also provides architectural finishing touches since it has no visible screws to the window frames. Well-thought out to the last detail.

Adaptable genuine wood interior window sill

With ONE, the wooden surface of the inner sill can be selected in accordance with the sash application, e.g. in spruce, larch, oak, wild oak.
 

Patio door with barrier-free threshold

Thanks to the  PVC material, the optional Isostep threshold  for the ONE patio door has particularly good thermal insulation and is designed for high water-tightness. The floor threshold is in black.
 

Sun shade- new design slat

Small Venetian blind packet with new slat shape C80 reduces the height of the Venetian blind packet when stacked up to 20% compared with the previous model and thus complements the simple and lean design language of the ONE.

Almost invisible insect screen

The first insect screen whose frames are the same width as the window frames. So inconspicuous that you think you are seeing the window itself.

Insect screen - 3-fold secured

Insect screen tenter frames are mounted at the upper corner. Strong magnets on the side and bottom hold it securely on the window frame. This way, the external window sill can be cleaned easily and quickly.

double glass bonding

Thanks to the special adhesive technology ONE windows are particularly resistant to cold, noise and wind. The glass panels are glued to the outside and inside tightly with the frame and thus create an increased burglar resistance and stability.

Strong structure. Slim design.

Although it has only 8 mm face width and 60 mm depth, the pilaster strip does not compromise on structure. This is ensured by a steel profile, which can optionally be powder-coated in the three interior colours and thus matching the interior colour of the window. For applications, the pilaster strip is always in the standard colour black.
 

Passive house compatible insulation values.

ONE has a very good heat and sound insulation. A core made of moisture and weather-resistant composite technology and thermally-separated aluminium ensures very good building structure and thermal properties despite its low system strength.

Sliding doors

FixFrame sliding door ONE S frameless

The slim, 5 cm ONE S frame width and the frameless look of FixFrame combine to create a harmonious whole. The barrier-free  sliding door ONE S  can be easily opened with one hand - without lifting. And that with a maximum sash weight of 500 kg.

Details matter

High-end glass design

In combination with the frameless all-glass system FixFrame One unfolds its full design potential.

FULL ACCESSIBILITY

Without the  slightest threshold, also called zero threshold , one steps out onto the terrace and into the garden. The boundaries between inside and outside disappear - without pitfalls and depressions
 

uniform handle design

Lean and shapely, the window handle is developed especially for the ONE, which is not only used for the windows, but also can be used for sliding doors, entrance and interior doors - everything cast from one mould.

Drainage

Did you know that 32 litres of water per minute flow off a standard glass wall (5 x 3.2 m) even during normal rain? That's 1,920 litres per hour. When the wind blows at the same time, it often presses the water up to 120 km/h against the door. Under these extreme conditions, the design drainage channel has proven its tightness in an independent testing institute.
 

Insect screen sliding frame

Insect screen tenter frames are mounted at the upper corner. Strong magnets on the side and bottom hold it securely on the window frame. This way, the external window sill can be cleaned easily and quickly.

concealed cable guidance

In our drainage shaft, the insect screen sliding frame runs up. Accessibility without tripping hazards. It also makes cleaning easier because dirt and leaves cannot get caught.

Sun shade - cable guidance - concealed

Why should you show the unsightly fastening parts when you can cleverly hide them under the drainage grate. Developed especially by Josko.

ONE S sliding door frame look

The  ONE S sliding door  reflects the lean frame look across the board. The barrier-free sliding door ONE S can be easily opened with one hand - without lifting. And that with a maximum sash weight of 500 kg.

Details matter

Symmetric perfection

A particularly beautiful symmetry is created when the sliding sash ONE is connected to the Fixed unit Blue. As all the elements of the ONE product family have the same frame width of only 5 cm.

Insect screen sliding frame

The newly developed insect screen sliding frame has the same visible width as the window frames. This provides you with an inconspicuous and elegant solution to keep annoying insects out.

Maximum freedom in choice of material

ONE Alu

Individually tailored.

Simple and elegant in design, the ONE Alu is available in three attractive interior colours:

  • RAL 9005 deep black matt
  • RAL 7016 anthracite grey matt (highly weather-resistant)
  • RAL 9016 white matt

NEW!
Upon request, you can now also chose from a wide rage of colours. For this, an additional Alu profile is snapped on the inside of the window frame, widening the visible width of the window frames  by a few millimetres t. For the fixed unit and sliding doors the visible width remains even the  same. 

ONE is available outside in many RAL, effect colours, powder coated or anodised.

ONE App

The freedom in choice of material and style.

For decades, you could choose only between wood, PVC or aluminium for windows. With ONE App, new opportunities are opening up. ONE's revolutionary App technology delights with beautiful surface applications for maximum impact.

In addition, the high quality wood surfaces in wild oak, oak, spruce and larch, walnut, black glass, brushed aluminium and genuine steel are also possible with ONE App.

ONE App also offers quite practical benefits: Thus, the decision for the individual indoor application is also possible upon request only after installing the windows. Damage to the application due to dirt, building moisture and construction work is avoided, as the App is only applied at the end.

These provide plenty of shade during the day and ensure that the temperature inside the house is balanced in summer. In the evening they primarily hold off curious glances.

With Venetian blinds and roller shutters Josko offers you the ideal solution. And because we develop and produce ourselves the sun shade also matches the integrated overall system and is carefully developed. Your advantage: No visually unsightly handicraft solutions from different manufacturers, no coordination of multiple contacts - everything fits together - in other words, a Smart Mix.
